Question about Rosewill R900J 19" Flat Panel LCD Monitor

54 Answers

Monitor goes blank less than a second after turning on.

I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up?

    Dell 19" monitor powers on fine displays image for a few seconds and then no image. Power light stays green no flashing. power it down and then back up shows and image and then goes blank again. same thing no matter how many times you trun it off and on.

    I have a Spectre DCL LCD model S1702D. It quit working, would keep trying to restart, but no video. After reading this thread, I opened the back, and replaced one bulging capacitor. Earlier posts said to replace the whole bank, I only changed the one obvious bad cap.

    This is your problem: Original cap was a 470 microfarad, 25 volt part. Since these monitors appear to be dying like flies, either they bought cheap parts, or the design is poor, and the parts are over stressed. I replaced my bad cap with a 470 microfarad cap (same capacitance value), but I put in a 50 volt part. The 50 volt part was too big, so I cut a small hole in the EMI shield for the cap to stick up through. There is another 25 volt cap in parallel, so it might be the next cap to blow. I have another 50 volt part to put in if this happens. If you put in the same part (25 volt), and the design is poor, you will blow those out too. you need to uprate to a more robust cap.

    Word to the wise. With 50 volt parts, this thing will be bulletproof.

  • Don Apr 19, 2008

    I have a Dell e771p Monitor and over the last few weeks I could not turn it off at the Switch, the led light would just remain on.

    I decided yesterday to pull the cover off and see if I could find the problem.

    It appeared that the Push Button was not touching the switch connector.

    I turned the retangle plastic spring loaded connecter over so that the contact would be made.

    I put it all back together and now the Monitor wont stay on, so I wacked a piece of sticky tape over the on/off button to hold it in.

    Not the best way to fix it but it works at present until I think of something else.

    Regards

    Flat panel monitor goes dark/black every 30 or 40 seconds.

    If I turn it off and back on it works for about 30 to 40 seconds.

    Now, as I'm using the keyboard writing this description, it stays on and works perfectly. I realize it's a settings thing but what?

    As long as the keyboard or mouse are active the monitor works.

    If I'm inactive it goes dark. Any suggestions?

    I have a problem that has been intermittent, but now occurs all the time, with my LCD monitor (AOS LM928, 19"). The screen goes blank on startup after less than 1 second on each display (motherboard, bios, XP, "welcome", desktop). The green monitor light stays on and the display will return, but just for the same period, whenever I turn off the monitor then turn it back on again. I have a Radeon X700 graphics card.

It's an LCD so the problem is most likely the back-light inverter board. Take a flashlight and shine it directly into the screen from the front. Can you see the image on the screen now? If the image is there but you can't see it without the flashlight than the inverter board needs to be replaced. This is a VERY common problem. Good Luck and let me know what happens, His Dudeness

OK PEOPLE I GOT THE SOLUTION TO THE MAG INNOVISION LT916S GOING BLACK AFTER ANY LENGTH OF TIME BEING ON!!! I JUST REPAIRED MINE TODAY! THE PROBLEM IS THE CAPACITOR BANK IN THE POWER SUPPLY PART THERE ARE 6 CAPACITORS I HAD A FEW LEAKY ONES "NOT GOOD" THE CAPACITOR SPECS ARE AS FOLLOWS 470UF 25V 105 DEGREES C MEANING 470 MICRO FARAD/25 VOLTS I HAD A VERY HARD TIME FINDING THE 25 VOLT ONES SO I WENT WITH 470UF/35V 85 DEGREES C THEY MIGHT NOT LAST AS LONG AS THE OTHERS DUE TO THE TEMP RATING HOWEVER, IM THINKING SINCE THEY CAN HANDLE UP TO 35 VOLTS IT SHOULD EVEN OUT AND HEY, ITS WORKING SO FAR SO GOOD!! THE CAPACITORS ARE FROM UNDER A DOLLAR A PIECE TO A COUPLE BUCKS EACH. THE CAPACITORS HAVE A BOLD LINE RUNNING UP ON ONE SIDE INDICATING THE POLARITY. BOLD LINE SIDE IS "-" SIDE WITHOUT BOLD LINE ITS "+" THE POWER SUPPLY BOARD HAS THE POLARITYS STAMPED ON THE BOARD ITSELF UNDER EACH CAPACITOR. EASY 30 MINUTE FIX IF YOU ARE LEARY ABOUT SOILDERING, FIND A FRIEND THAT KNOWS HOW TO. ITS REALLY NOT THAT HARD THOUGH AND YOULL HAVE SOME DECENT ROOM TO WORK WITH. I PROMISE WHEN YOU OPEN IT UP YOU WILL ALMOST CERTAINLY SEE AT LEAST 4 OF THE 6 CAPACITORS BULDGING AT THE TOPS MAYBE EVEN LEAKING BROWNISH STUFF. DO YOURSELF A FAVOR THOUGH AND REPLACE ALL OF THEM WHILE YOUR IN THERE "THE SIX BIGGER ONES ONLY" IF ANY OF YOU NEED FURTHER HELP OR ANY OTHER QUESTIONS ABOUT THIS PROJECT PLEASE FEEL FREE TO EMAIL ME AT BTLEE26@HOTMAIL I DAMN NEAR WENT CRAZY TRYING TO FIND A SOLUTION ON HOW TO FIX THIS THING SINCE I SPENT OVER 300 BUCKS FOR IT NEW. AND IM BY NO MEANS A EXPERT WHEN IT COMES TO THIS STUFF BUT I DO KNOW A FEW THINGS. AS IM SURE MOST OF YOU DO.

    TO THOSE THAT DID NOT HAVE THE SAME CAPACITOR PROBLEM THAT I HAD, IVE BEEN TOLD THAT IT MAY BE THE INVERTER, AND UNFORTUNATLEY I DO NOT KNOW WHERE TO GET THEM OR HOW TO FIX THAT PART, AT LEAST GIVE THE CAPACITORS A VISUAL FOR SIGNS OF BULDGING AND/OR LEAKAGE. LIKE I SAID THIS WAS THE PROBLEM FOR MOST OF THE PEOPLE IVE RECIEVED EMAILS FROM. ALSO, TO GET THE FRONT BEZEL OF THE MONITOR OFF, UNSCREW THE SCREWS ON THE BOTTOM PART OF THE BEZEL, GENTLY PULL THE BOTTOM PART OUT FROM THE BODY OF THE MONITOR AND WORK IT UPWARD TWARDS THE TOP. IVE HAD A FEW PEOPLE ASK ME HOW TO GET THAT PART OFF CAUSE ITS A LITTLE TRICKY TO REMOVE BUT WORKING IT UPWARD SHOULD GET IT OFF OF THERE GOOD LUCK EVERYONE!

Temporary get you working fix. These back lights work similar to a striplght in your ktchen where the need a starter but in ths case an electronic starter in the nverter board. Now I have one of these monitors that flashes on at startup . You may find that if you repeatedly plug/unplug the Dc power jack a few times in very quick succession it will spring into life This mimics the electronic boost the starter gives the fluorescents on startup. warning this is not a solution to the problem but something you can try to get you working. I recomend you get the inverter/ fluorescents repaired. also you will probably find that it wont subsequently light up after power save mode switches off the monitor. This info may be of some help to someone to get them out of the "doo doos" but not recomended long term.

Your computer is probably fine. More than likely the inverter board for your LCD has gone bad. The inverter board powers the back lights in your LCD. If you will take a flash light and shine it directly at the LCD you will probably see the display very dimmly. You can purchase the board and swap it yourself or you can pay someone to do it. Either way it will be cheaper than buying a new LCD.

LCD COMPUTER MONITOR symptom: you turn power on, but the screen goes black after a few seconds. Usually happens after a year or more out'a the box (and beyond the warranty). Most likely, you've got defective capacitors on your power supply (invertor) board. Mine were bulging out their tops; this happens when the DEFECTIVE wet electrolyte drys out, gets very hot and creates gas that tries to escape. The result is drastically reduced capacitance, and ultimately a blank screen.

I ordered 7 new caps on Ebay for $5 and replaced them myself. Monitor works fine now, good as new. I've since learned there is a rash (tens of millions) of bad caps out of Taiwan that have made there way into tons of monitors and other devices. The caps for my $300 Gateway FDP1960 19" LCD Monitor were the 470uF 25v 105C type, and the 220uF 25v 105C type. If you're a competent hobbyist or tinkerer, you can do this repair yourself. In addition to your soldering iron, you'll need a solder suction tool.

After you unplug the power cord (!) and remove the screws on the back, you split the case with a screwdriver (scotch-taped to prevent mucking the finish) by prying/inching along the perimeter bottom and sides. It requires some unusual force to open, but that's how they're made. (If you're reasonably careful, it will snap back together, later, after the repair is made).

Once the case is open, you follow the obvious by removing screws, the screen, cover, and then finally access the power supply (the one with all the bulging caps). As always, be sure to unplug the thing before opening!

    Hi, I got the same problem. And this is the way how to examine where the problem is. You have to check that if you can see the image on screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons (Power on both cpu and monitor), there will be a minor problem. Like mine, I can see window image using flashlight and check lamps inside. Some of them were broken and it is very easy to replace but take longer time to order and shipping. If you cannot see any icon on the screen. I would say that there are some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or dark spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

I agree with rifleman the inverter board has gone bad due to 4 or 5 bad capacitors. If you know what you are doing you could replace them yourself saving the cost of a new inverter board.

I am having sorta the same problem with this same monitor. The only difference is taht mine stays on for about 30 mins then shuts off. The green light is still on, but if you turn the power on and off it will come back on for about 3 to 4 seconds then goes blank again. If you let it sit for about 5 mins it will work for around 20-30 mins. I dont know if it is the invertor board or whatever you said earlier i was just wondering if it was the same thing. Because I would rather pay 90 bucks instead of 300 for a new monitor it just makes sence

The problem with most benq moniors is that the inverter fails. The solution is to replace 2 2sc 5707 transistors and 1 fun9024n mosfet. there is also a fusible link that is open circuit. The reason they go bad is because the formers are dry jointed. also heatsinking the transistors gives it more reliability.

I was given an HP pavilion f1503 with the same problem. Turns on, goes black. Using a flashlight I was able to see my desktop once it loaded. I opened the monitor and found cold solder joints on the coils. I very very gently sanded them and re-soldered. While I had it open I touched several of the "cold" joints with the iron. Let them cool at room temp, put back together, and started it up. Works fine now for almost a year. Its not always a bad inverter. Cold joints appear gray instead of silver (solder) and are EASY to fix.

Posted on Oct 10, 2009

  • taway Nov 06, 2010

    Actually this monitor is still working fine. Solder joints need full contact to conduct and these were badly soldered and cracked. Very lightly sand them off and resolder and almost 2 years later this monitor is still working fine. But not all similar problems come from cold solder apparently. I was lucky this was mine because it was easy to fix.

Hi, I have two 19" Zerox monitors and i'm slighty annoyed, because its only just been over a year, (literally 7 days) and one of them is playing up. Its more and likely going to be the inverter board, but if your desperate to get the thing on, try this, turn it on, then as soon as you get a picture press and hold the menu button down and it will miraculously flick/brighten up, like its ignited. Do try it a few times though, but its worked for me. Will have to get it fixed, looked for prices for inverter boards average £15-20, but hard to find an xerox one. I think it shouldn't cost more than £40 max to get it fixed or D.I.Y it.

Replacing the power cord has worked for me in the past, but turning on the monitor and holding down the menu button did the trick! No soldering for me :)

I just posted a fix for the blank screen after seeing XP.
All I did was to press the "Auto" button twice and it reconfigures itself to auto fix itself back to normal.

Try this on yours. It worked on mine and I was ready to chuck my monitor (literally) on the bin. Was also ready to pay a technician to look at it for me.

I was told I had to pay $40 just for them to look at it then I will have to pay if they're going to fix it. I heard him mentioned coz the parts are not the normal parts he will have to look online for a fix.

So, I took it back and did the search myself online and found it.

Hope this helps you.

I had the same problem with my LG monitor. it was on the inverter board - a 680uF, 25V electrolytic cap. The top had "mushroomed? and when I removed the cap it only read 178uF, and had high ESR. Since I was in there I replaced the other 680uF cap, several 1,000uF caps, and 2x 470uF caps. Most of them were reading other than labeled. The monitor has been working fine since. I got the caps from Mouser Electronics on line - the parts were here within 3 days, and it took about 15 min.s to change them all.

If the computer turns off, you may have a power problem - newer Intel boards have an extra power connector that needs to be connected to the board, so make sure you've done that - your power supply may be on it's way out - try substituting a new one If the computer remains on but fails to boot, you may have one of a host of issues - check to see that your hard drives, add-in cards, your graphics cards and memory, are well seated and connected well (push them in firmly) - make sure that your mobo jumper for RAID are set correctly - try resetting your CMOS by changing the jumper, starting, then changing the jumper back (refer to your mobo manual) If your computer stays on and boots fine, your monitor may be broken. Try another monitor to check

I have a Compaq FP 7317 and have the going blank after time issue.
After much reading an some play inside i havnt solved the issue entirely.
But i have found if i turn the bightness down to 0% the screen will stay on fine.
If i increase the brightness to 20% it will work for about 1 to 2 hrs.
Ive tried to check for dry joints but only a quick visual will go more in depth with my multimeter to see what i can find.
Hope this might help someone as atleast i can use the LCD now

Common LCD problems & probable causes:

Blanks out, Dark Display - Defective Inverter , Lamp, Controller board

Flickers / Lines on screen - Controller board, LCD panel, Power supply

Dead - Power supply, Controller power circuit

Dim / Darker than normal - Weak lamp

Display blinking - Power supply /inverter board

Dude. Push either the + or minus button between the MENU and AUTO/SELECT buttons. The + selects the DVI input and the minus selects the VGA. I suspect you are currently mismatched.

I recently hooked up my desktop to a wireless router and everything was fine until I shut down my computer to move it to another location. Once I did that the monitor would not work...same problems as listed in all the other posts. I am not an overly computer literate person but I tried everything that I knew and finally for some reason I tried a different power cord. (only the power cord to the monitor, not a new strip plug) THAT FIXED MY MONITOR. Not sure why the power source would have been the issue, but using another cord worked.

It could also be possible there are supression coils in the circuit of the inverterboard they are not good cleaned before soldering in factory and the time to soldering was not long enough so it is sometimes that will work and sometimes not that is by the most lcd monitors a point to always give an extra attention most times they are mounted with silicone take it out scrape the ends clean because sometimes there is too much insulating lacquer and solder them back again, this has been replaced with all the good will in the world an underestimated problem, I have repeatedly experienced the capacitors with Fujitsu Siemens and Acer is beautiful is not always enough

Your LCD or LED panel is suffering from backlight issues. If the monitor says its on but you can't see the image, try to shine a light on it. If the image is somewhat visible, then your backlight needs to be replaced. Call your product's company customer support, and don't try to fix it yourself unless you know what you are doing.

Check your inverter board if any leake capacitor. you can replace should work your monitor

Posted on Aug 28, 2009

I solved my problem of LCD monitor (AOC LM928) continually going blank in less than a second, effectively by simply removing the strip around the front of the monitor!

I have concluded that my problem, which had progressively got worse over 15 months or so until it was permanent, was that one or more monitor buttons, probably either the power button or the auto button, was pressing permanently against the switches behind (through the plastic component between) continually triggering display cut-off.

Posted on Jul 14, 2008

I just fixed my dell 17 inch LCD monitor by replacing 1 of the bad (leaky) capacitors. fixing it myself = $1.70 dollars.

Posted on Nov 26, 2007

I have seen the problem on my brand new Dimension E520. There is an issue with the ATI drivers, so you should make sure you have the latest versions before you resort to getting the soldering iron out! If you started seeing the problem after a Windows patch update, suspect the software first.

Posted on May 30, 2007

Most likely the LCD has gone bad, or backlights I sould say. Cheap if you work in a place where electronic things are laying around.

Posted on Apr 17, 2007

Solution #4 was the fix for my Benq flat screen, the parts cost me about $3 at Radio Shack. Thanks for the help.

Posted on Mar 08, 2007

The power supply board inside your LCD monitor has 6 bad capacitors. If you remove the power supply board, look for the bad caps that are buldged up on the tops. These caps are all standard values that you can get at any electronic parts store. Less than $10 and about an hour of labor will do it.

Posted on Feb 28, 2007

If you see picture on LCD when shining to the panel with flashlight as someone worte in first solution, the problem is in the inverter board as has been written. You may try to change electrolytic capacitors on the inverter board, there usualy are only few of them and they are cheap. But you need basic skill with soldering. If doesn't help you have to change the inverter board.

Posted on Jan 30, 2007

I had the identical problem; in my case, and I'm guessing in yours, the flashlight test fails, i.e., the problem is not the backing light. I recently gave the monitor away to a gentleman who claims to have found the problem: the monitor is overheating and automatically shuts off for safety purposes. He says that he fixes these monitors by opening them (this is difficult) and then finding the loose connection causing the problem and resoldering it (somewhat less difficult).

Posted on Jan 12, 2007

Also check the connections to the backlight tubes. Mine had a dry joint on the pink wire. Monitor runs then inverter shuts down as the tube currents are unbalanced.

Posted on Jan 11, 2007

Sounds like Rifleman may have the answer. I too have this issue and have not been able to figure it out after all sorts of testing, etc. Off to track down a flashlight. :P Thanks!

    My monitor is doing the same. It goes blank after the first few seconds. But the light stays blue on the monitor. Can I just buy a whole new monitor to fix the problem?

×

I have the MultiSync LCD1700V monitor and it was on for about a half second then off. Tried the flashlight - No go. Turned on and off several times - No go. Then did something off the wall - pulled the power on the back and replaced it - BINGO it works. Analyzing this I found that I had problems inserting the power plug and must have dinged around with it several times then inserted it before it came on. Has been running for over a half hour with no outage. GOOD THINGS HAPPEN!

Generally, when the monitor powers on, then goes blank very fast, it's usually a power supply problem. I have two LCD flat panels that had bad power supplies, both work great since I made a Mollux connector adapter for it. These are easily made from a Y connector, or any adapter that plugs onto the Mollux connector on your computer's power supply. However, since this takes 19 Volts DC, there may be a problem with line voltage, or amperage to power the monitor.

When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.

Change the monitor and check if the PC works. If it works then the problem is with the monitor, you will have to send it to repair. If not then, the problem should be with the power supply, check whether all the cables is kept intact.
