If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
?Check the cables, connectors and connections.
Take it to a repair shop.
It sounds like there's a problem with the monitor itself. It may be that the lamp in the computer is dying, which would explain why it keeps going out. Other possibility is that the monitor isn't receiving power properly either through the cable or inside the monitor itself.
If your're not the kind of person who wouldn't mind opening the monitor up and hopping in there, then I recommend you take it somewhere it can be diagnosed like Best Buy.
this is capacitors problems inside the monitor. If you have some tools , screwdrivers, soldering iron and some experience, open carefull the back of your monitor after to unplug from the outlet. you will see in power supply board a capacitor who which the top has changed . replace that capacitor.
Ok, another words, monitor powers up for few seconds and shuts down by itself. If green LED on the front panel turns off as well or stays on? If stays on, then inverter turns into protection mode because of old backlight lamps. If it turns off in same time with an image on the screen, then there are some bad electrolytic capacitors in the power supply.
It sounds like your resolution or refresh rate is out of reach for your screen.
Restart your computer (even if it will be manually unplugging the power cable)
If you have no display while your computer starts up; you might have a hardware failure. Swapping your screen out, or plugging it into another computer (that works) will confirm if this is the issue.
If you can see the computer starting up you can press F8 (on your keyboard) continuously just before Windows can start.
Select "Safe mode" so that you will have the basics of screen settings.
Now you can go to control panel, display and click on the Settings Tab at the top. Change your settings to a rather default "1024x768" resolution and change your referesh rate to nothing more than 75hz under the advanced icon.
You have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts, replace any that look like the pictues and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

Could have blown some capacitors inside the monitor. I just fixed one today that had no power, the blue ring around the power button didn't even light up when plugged in. I open it and found 3 bulgingcapacitors on the power/inverter board. They were all 25V 470uF rated capacitors. Went to radioshack and found 2 35V 470uf, got them at $1.29 each, then I found 1 50V 470uF out of a dc car power adapter for an ipod, it was as close as I could find. Replaced the 3 broken/bulging ones with the new/salvaged ones, put it back together, plugged it in and the blue light came on when I pushed the power button. Plugged it in to my laptop with vga cable, and it works great.
I have a Xerox XA7-19i. It has the same problem as described by many
others - intermittent fault with the display that manifests as a white
screen when the monitor is first switched on. After a few trys of
switching on and off, the monitor works fine until left off for a few
hours. Recently, the problem deteriorated to no light from the panel,
and a flashing blue power light.
I HAVE SUCCESSFULLY REPAIRED MY MONITOR:
I opened up my monitor and removed the power supply board. I de-soldered every electrolytic capacitor, and replaced them with new capacitors of the same uF and voltage rating. I put the monitor back together again and switched it on - it worked perfectly!
- these monitors have been built using sub-standard / under-rated
electrolytic capacitors. After two years of use, the power supply board
was unable to supply enough power to the logic board and backlight,
causing the above-mentioned problems.
The repair cost me ~ GBP
15 (USD $30). It is not a difficult fix, but one only to be attempted
if you have electronics knowledge. Careful, kids! you'd be playing with
the power supply of a mains AC electronic device. That stuff can kill.
- I saved myself (and the environment) from having to throw out a
monitor and buy a new one. If you have a faulty xerox monitor and are
getting no love from Xerox customer support, find an electronics geek
and ask them to replace the electrolytic capacitors on the power supply
board. (but be careful to get the right kind of capacitors, and to get
the capacitor polarity correct. If you have any doubt as to you ability
to do this, don't bother trying!).
