Having problems with your Xerox XG-91D 19" LCD Monitor ?

Faulty Monitor? I bought one of these Xerox flat panel 19 inch monitors to replace my convention Sony unit about 4-5 months ago. It has worked just fine until about 7 days ago. Are there any known problems with these Xerox units? I turn my computer off during the day, when I am at work. I also turn my computer off during the night when I am asleep. At those night times I also turn the 'blue power button' on the monitor off as well, as it will flash annoyingly in the room if left in the 'stand

\015\012 I layed my on a clean towel. Like they said remove the stand first. Then the 2 screw's on the back side near the bottom. Then push the glass down about a 1/4'' .It took a couple of tries to get the glass to push down. Then lift the glass off the front of the monitor. Lay the monitor on it's back. There are 6 screws that hold the screen in place. Gently lift the screen up, on the right side are 2 sets on wires to disconnect. On the upper left side there is a small ribbon cable gently unplug it. Then you can lift the screen out. Now you will see a metal cover over the power supply board and the other board. There is about 6 scews to remove and then the metal cover will come off. The power supply board is on the right side. In order to remove the board you need to remove the screw holding the green ground wire down, It is on the lower left side next to where the black plug in, for the power cord plugs in. Now you need to gently pull that black plug up and pull the wires towards the right to get them out. On the power supply board there are 4 screws holding it down, also on the upper left side the board has a 6 pin connector where it plugs into the other board, gently pull it up. Now the board is out and you can take it to radio shack to get the capacitor's for it. I replaced, all 6 of the big ones and the 1 small one. I had to go to 2 stores to get all 6 of the big ones. Radio shacks item # for the 6 big ones is 272-1030 and the one small one is item # 272-1029. I also bought a pencil sodering iron and some soder they suggested. I spent $25.00 to fix my monitor. After reading the posts on here i figured i could do this. It took me about half a day to do this work. I also copied the posts to Microsoft Word on my computer so i could print out the posts to help me with doing this work. I also saw a few posts where some of you were asking for more help and directions on how to do this. So this is my way of thanking the people who already posted about fixing their monitor.

\015\012Thanks again for the post from Xeroxfixed posted Mar.16, 2008 and guest posted may 8, 2008 with out those that monitor would still be sitting in a box in the house collecting dust. Now it is on my wife's desk and she is happy to have it working again. We bought because she really liked the glass front on it.
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!
