Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Computer monitor becomes distorted after boot up.


Hi,

Download and install the correct driver for the monito as well as the deiver for your video card, if the video is onboard, you may need the motherboard and AGP driver as well.
You will probably need to boot in Safemode to do this.
Good Luck.

Blank screen for 15-20 minutes at startup


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!

Yes - 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.

But - 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!).

Good luck!
