Question about Sceptre X9G Komodo IV 19" Flat Panel LCD Monitor

2 Answers

Unidentifiable capacitor? After opening up my monitor I noticed on the power supply side a capacitor that is slightly bulging, however the number on the capacitor was EJ(M)105(degree symbol)C (c)0424. A guy at Radio Shack said it wasn't a capacitor with those numbers on it. It looks like one so does anyone know what it is? Thanks for any help.

This trouble maybe power supply or inverter boards is defective.
first you can test the voltage of the multr,and then check which part is defective.From can find those parts
if you have any question,please let us know,we sincerely hope we can help you!
you can also check this boards whether suit you:

Re: unidentifiable capacitor?

What i would suggest is taking those numbers going to your favorite search engine and entering them. Alot of times search engines can give data concerning hardware parts just by there manufacture number. This will give you a foundation to find what that particular part is and also maybe a replacement part. A word of caution about working with capacitors. Even after power has been off for several hours they can still hold a deadly charge. If you have a volt meter I would use it to test the part before even thinking about it. Capacitors are nothing to mess with unless you have proper knowlege on how to handle them and discharge them.

I have SVA VR 15A Flat Panel LCD Monitor . but not be on, his problem is a i attache to VGA Cable with PC and on it , but first time he is on only 3 second and then ,end the his screen display but power...

The power supply has a bad capacitor. It's 4700uf at 16v, electrolytic. You'll notice it from the slight bulge in the top that may be very apparent or barely visible. Replace it with a LOW ESR cap of at least the same voltage rating as the original if not greater. Simply de-solder the old one from the psu board using a soldering iron and some solder wick, insert the new capacitor, polarity correct, and you should be fine.

The capacitor will cost about $2.00 not including shipping. Here's a link to Mouser. Don't buy this capacitor until you've verified the value and voltage from the one on your monitor power supply. It's alright to use a slightly higher (up to 10%) value of capacitor and the voltage doesn't really matter as long as you're over the rated voltage of the unit you're removing.

Don't do this if you have no experience, the voltages are high enough to hurt you and you may regret it. This monitor is worth less than the cost to repair it but if you're set on it fine.

What are bad caps

you will noticed if the capacitors at the power supply board is bad if has bulged to its casing or blown up. but sometimes even with out sign of bulged but its leak, you can determined this by using a capacitance meter.

That is s typical problem with monitors usually it results from power fluctuations. That means that the capacitors in your monitor have been burned out. The capacitors in your monitor have the ability to hold down the power long enough for your display. When you switch on the monitor, the power is kept in those capacitors so that you can see the display. Faulty capacitors will only hold down the power for a maximum of 8 seconds depending on how bad the capacitors. Here is the solution, open up your monitor using a flat-sharp object starting from the bottom splitting it out working your way to the top. You will notice finger-like structures that hold down the covers together and make sure you do not break one of them.. When you open it identify the circuit board where the power supply is connected, that is where the capacitors are located. Check for leaking or bulged capacitors, those are the faulty ones. Go and buy a new one and replace the faulty one.

Display for a few second

That is because your monitor has faulty capacitors. Capacitors in your monitor have a job to hold down power as it comes from the source long enough for a proper display. The only way to get around this problem is to open up the monitor (You can get a computer technician to do this for you if you can not do it by yourself). Or you can get a sharp - flat object and start opening (splitting) the two covers apart from the bottom of the monitor. You will notice finger-like structures that are holding the covers together. Make sure you do not break any of those. When you open it up, then check the circuit board where the power supply cable is connected. Check for any bulged or leaking capacitors. When a capacitor is bulged or leaking, it only holds power for at least 2 to 8 seconds then looses it. Buy the same type of capacitors and replace the faulty ones. Make sure you note the polarity of the capacitors before replacing (+ and -). This will definitely take you out of your trouble

When i'm on my tft it show the disply suddly sceren goes on dark .

That shows that your monitor has failing capacitors. Capacitors in a monitor are responsible for holding down the power from the supply so for a proper display on your monitor! What happens is that when you switch on your monitor, the capacitors hold power enough for a normal display on your monitor. This means there are failing capacitors in your monitor. The only solution to this is to replace bulged or burst capacitors. You can get a Computer Technician to do this for you or you can do it for yourself. Open up the monitor using a sharp flat tool (knife or anything like that) starting from the bottom, working your way round to the top. You will notice the finger-like plastic clips that hold up the two sides together. On the circuit board where the power supply is connected, that is where you are going to find the capacitors. Check for any bulged-head capacitor. Replace the capacitors with the same type of capacitors (for example 1000u 10v). Make sure when replacing it to note the plolarity (+ or -)

Monitor was ok one min. then power supply died the next. is there some sort of reset button?

No! unfortunately there is not, if the monitor is dead chances are it is one or two bad capacitors in the power supply that usually have a slight bulge on top indicating it is open.

Monitor flicers when starting up takes 15 minutes bbefor it comes on. monitor aprox 3 yrs old

This a common problem in the Samsung line, there are usually bad capacitors in the power supply and inverter board. They tend to bulge slightly at the top indicating an open situation, your description is typical of one or two bad caps in the power supply section that need to be replaced.

I have a samsung Syncmaster 932bw and turned it on and noticed a real bad flicker ran all the tests i could find other then your flashlight test cause i dont think it pertains to my certain problem. after...


The flickering picture usually indicates that the power supply is failing. The most likely cause of the power supply failure like this is capacitors either drying out or bulging from over heating. We have a page on our web site at: This article wexplains what capacitors are, what you will need to look for to identify the failures and which brand and series to get tof rht replacements. In most cases you can open the monitor and look over the power supply and see obvious bulging on the capacitors that are failing. If you replace them you should be back in business. If you have additional questions just let us know.

I hope this helps, if so please rate our solution.

When power is applied to the lcd monitor vx922, then green light ON and the screen shows dispay for one second and then screen shows dark screen permanently

If obtaining the capacitors is a problem you can purchase a replacement power supply from the Viewsonic store. I just performed the repair on my VX922 and it works Like a champ. The replacement power supply is Part Number B-00003993 PSU - Supply (ADP.INV, FSP043-2P101 90"264V GP) according to the invoice. The total cost shipped was about $35 when I ordered it on AUG 5, 2009. It was quite easy to do and took 30 minutes. The monitor is working like a champ. The capacitors where in fact swollen but that led me to believe that other components may be suspect hence the decission to go with the entire supply based on the minimal cost and lack of availability of capacitors. Tools needed were phillips screw driver set, nutdriver for removal of VGA and DVI locknuts/capstands, cuticle scraper for removal of internal connectors and monitor case clips and a "Bennifiber" measuring scoop (to seperate the monitor case halves without scratching). Be careful when removing the aluminum insulating tape holding the connectors and planar boards down or it will tear. If you have "aluminum" duct repair tape it will suffice as a replacement. Also you will need to remove the tape on the sides to gain access to the screws mounting the cage holding the power supply and inverter assembly.
