Question about ASUS Computers & Internet

My ASUS (VW190) LCD monitor shutdown for 1 to 2 seconds after turning on with full image then the LED indicator is still in blue color. Once I press the power button off and on, the screen displays again with full image then full black out after 1 to 2 seconds. What could be the cause of this and anyone knows how to fix this?

SOURCE: Sceptre X9G Komodo IV

I have a 19" Sceptre Comodo display. After 3 years it got the problem everybody complains about. Took it apart yesterday.

There are 4 capacitors in a row on the power supply board (it has a socket for the power cord and is covered by a metal shield. The caps are barrel-like things standing upright on the side opposite to the power cord socket.) Two of them are 470 uFx 25 V, they are next to each other. In my case, one of them popped up and another one was bloated. I pulled out the power supply board (make sure you unplug the power cord and press the power button do discharge the high voltage caps before messing with your monitor) after disconnecting all sockets (mark'em!). I assume that you have new caps handy (I paid $2.10 for a pair at a local electronics store), they must have the same capacity and voltage rating. Now grab a soldering iron, remove old caps, and put new ones in. You must observe polarity! (Usually "minus" pin is labeled on the cap's side. Mark down "minus" and "plus" pins location of old caps and put the new caps in exactly the same way! Otherwise, you can blow the caps.) If you are not used to work with a soldering iron, hire somebody or buy a new monitor. Check the quality of the work (no shorts, solid contacts, etc), assemble the monitor back and may be it will work (did for me). If it does, you put one monitor less into the city dumpster, be proud to get a working monitor for less than $5, and force you mother-in-law to take this shiny new replacement display she just bought back to the store.

Of course I do not guarantee that my procedure will work for and you can use it at your own risk only (i.e. I am not liable for any damages).

SOURCE: blinking monitor power button and flashing image

I buy and sell these monitors (Dell E17FP) the problem is with the transisters (Q739, Q740, Q759, Q760) they short out and the monitor will just blink on and off. You have to desolder them and test them with a simple battery and light circuit. The reason they blow is because of the dirty solder joints by the transformers. If only on pair of backlights work the problem maybe transisters Q751, Q743. I home this answers your questions.

SOURCE: When I press the power button LG displaying chars for 1 second

Had the same problem, turned out it was due to a faulty capacitor on the inverter board, 680uF 25V (105 celsius rated). Simple to fix once you have the unit dismantled and the correct replacement part. Two screws hold the shroud on, but you need to be careful with an (old) credit card levering it off.

Unit is now working fine.

Monitor picture comes on for only 1 second and then it is blank (black) Color bars appear to be OK (for that second) when running the Self-diagnosis function.


timothy henr, Do you understand how the new screw-in, curlie-Q, energy efficient, CFL light bulbs generate white light?? You will when you find out just what makes the WHITE fixya background on this web page you are looking at!!! Black screen of death can strike at any time!! Do a reply when finished with your research of repair video clips at YOUTUBE. Your search terms are: "lcd monitor disassembly" and "lcd monitor repair." That should get you started. Your unit could have a "switch-mode-power-supply" that detects a problem with itself or another circuit and goes into "full" or "partial" shutdown mode. You should be able to tell the difference if you shine a bright flashlight 1 inch from screen when it goes black!! Partial=still see win-desktop. Full shutdown=no see desktop!!! What wil you do??? Fix or just trade up for new display?? 12fixlouie

The screen flickers on for a fraction of a second and goes black. The light at the bottom says its on and I tried using a different monitor on the same computer and it works great.


natehoop, Ok, we know it is BLACK!!! Now connect it to a fully booted known-good pc with WIN-desktop being displayed. Then point a flashlight 1 inch from screen and tell me if lcd panel is BLANK, or if you can see very, very faint image of the desktop?? If you see image = power supply in partial shutdown mode!! If you see nothing = power supply in full shutdown. Unit suffers from "Black Screen Of Death" You should watch some repair videos over at YOUTUBE first to learn about the CAPACITOR problem. then come back here and do a reply stating if you will attempt a diy repair or other option. 12fixlouie

Hannspree HF229H will not stay on


railbird56, Common problem for ALL BRANDS of "cold-cahtode-fluorescent-lamp" back-lit lcd monitors! Here are your options!!! Cheapest to most costly!! 1. Warranty repair. 2 DIY repair???? 3. Local or distant repair. 4. possible old + cash swapout with Hannspree for refurbished same model?? 5. Trade-in for new wide screen. My best guess on your monitor (no history) is that the unit's SMPS is in partial or full shutdown mode during it's black screen moments. How much do you know about "electronic ballasts" "switch-mode-power-supplys" and how to repair them?? 12fixlouie

My monitor will not stay on and goes black after a few seconds when I reboot it. I'll turn the monitor on and it stays on only for a few seconds but I can see all of my programs for those few seconds.


maryfoldesi1, Your monitor power supply is going into shutdown mode becauce it has detected a fault within the unit. A technician will need to evaluate it. Before doing anything visit YOUTUBE to view vid clips of "LCD monitor disassembly" and "LCD monitor repair" Also read more of my responses to other owners that have BLACK SCREEN problems and find out all your options you have open to you. You did not tell us if you can still see the Win-desktop AFTER it goes BLACK. Is it also BLANK or can you still see a faint image on lcd panel if holding a bright flashlight 1 inch from screen? lmistyrel on aim.com 12fixlouie on fixya

The panel initially displays and then goes blank


johnerm, Good going John! At least YOU tried doing a swapout to another KNOWN GOOD pc to prove out that the E153FP is indeed the culprit!!! Now for the hard part. Do you have a bright flashlight? Reconnect E153FP to pc with WIN-desktop as the displayed image. then and only then turn on E153FP and note the time it takes to GO TO BLACK SCREEN. Is it 1, 2, --5,---20 seconds???? Now point at different angels about 1 inch from screen a bright flashlight to an area that "should" have a desktop "icon" showing. LOOK very closely!! If you SEE a very faint image of the desktop the units "switch-mode-power-supply" is in PARTIAL SHUTDOWN mode. (still has +5v or +3.3v to supply vga/lcd interface board) If you SEE NOTHING, then SMPS is in FULL SHUTDOWN mode. Get back to me, 12fixlouie with your SMPS flashlight evaluation and pay a visit to YOUTUBE fyi search and view video clips of "LCD monitor disassembly" and "LCD monitor repair" to see if DIY interests you! Also try www.ccl-la.com/badcaps.htm run by another tech on fixya nickname "buddymc" fyi. If this was of some help, rate this response on fixya. 12fixlouie aka louie12fix or lmistyrel @ aim.com

My Samsung 943N LCD monitor will work for 1 second and then goes black. When I choose the extended desktop option, for example, it will flash my desktop on the monitor for a second and then go black. I...


becky_bitz, Do this first! It is only a "rude&crude" evaluation of the state of the monitor's "switch-mode-power-supply" Reconnect 943N to a fully booted KNOWN GOOD pc that has WIN-desktop showing. Then and only then, turn on the 943N and note what happens. After the screen goes BLACK, shine a bright flashlight at the lower left corner to try and see if the WIN-START button can be seen or other desktop icons are being displayed even though the LCD panel appears to be black! If you see a very faint image the SMPS is only in partial SHUTDOWN and is still powering the VGA/LCD interface board to display the images. If you see NOTHING, then SMPS is in full SHUTDOWN mode. In either case, your monitor's SMPS is trying to save itself from a catastrophic, nonrecoverable failure.(smoke,fire) Becky, fear not the those last two words. In fact your words "work for 1 second" means that the 943N is a good candidate for repair even if to keep as a working spare! To help in your decision making process you should pay a 30 minute visit to YOUTUBE and search out and view some of the longer video clips of "LCD monitor disassembly" , "LCD monitor repair" and also visit some websites you find here on fixya. www.ccl-la.com/badcaps.htm , www.lcdparts.net , www.badcaps.net are just a few that will point out what is causing your "cold-cahtode-fluorescent-lamps" to fail after 1 second. If you still need help then do a comment to your original post and I will try to help you. lmistyrel @ aim.cm or 12fix louie on fixya. If this was of some help please rate on fixya.

Starlogic 20 inch widescreen monitor screen keeps going black


This is probably a back light problem. Take a bright flashlight and while the monitor is on, point it at the LCD and try different angles, etc. If you can see an image, it is the back light, probably the back light voltage converter unit in the lcd. It could also be the back light bulbs.

If you don't see an image with the flash light, then it could be the main logic board.

Monitor image comes up, then blacks out, power still on


Hello David,

This is very common problem and is heat/age related, but It can happen to monitors that are no more than a year old. It is usually bad capacitors on on power inverter board. I just fixed two monitors with this problem. This problem is common across all brands. Look for several radial capacitors in a cluster on the power inverter board. If some are bulging or have a slightly domed top, they are the ones that are bad. I usually replace all the capacitors in this small cluster because some may be marginal. This is easy to do if you have a bit of electronics skill.
