Question about Xerox XG-91D 19" LCD Monitor
I have also fixed my wife's Xerox monitor Thanks to all the posts on this website !!! I just fixed it yesterday. It was fairly easy.
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.
Thanks 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!).

If capasitors are ok, but you have this turn off after few sec. problem it may be coused by the backlight bulbs or inverter drivers. You can detach driver chip pin 2 - protection. And it will let you use it for a while :)

I have the same problem where the screen displays for 2 to 3 seconds and goes blank. I replaced the 6 470uF and the 1 220uF capacitors. No help... still does the same thing.

Unbelievable 7 capacitors later and my monitor is as good as new - Thank you guys - very helpful information.

Thanks CRONLARRY i did exactley what you said with my Xerox xg91d . i ordered the capacitors from radio shack using the part # you posted. screen came right on! works awsome.
i got my xerox xg91d from "Goodwill" store for 10.00 !!! it didnt work when i brought it home.

I replaced the 6 470uf 25v and 1 220uf 25v capacitor as detailed
everything works fine now no problems at all doing the job, hope it works for others.
Thanks to the guy with the solution,cost me 1.20p plus postage for capacitors.

I decided to follow the advice posted here and went to radio shack and replace the ccapacitors in the power supply. Unfortunately that didnt work for me although this time the monitor would stay on for more that 30 seconds but it would flickers some and dim down before the screen going black. so i finnally gave up on it since i replace all the capacitors. I decided to throw it away but not before have taken the whole thing apart, i mean the whole thing apart. I came to the conclusion that the problem is not on the power supply itself but the fluorencent light bulbs that illuminate teh backing of the lcd glass..lik ei mentioned before my moitor started flickering with the new capacitors installed, (somethign that it had not done before) when i took the screen pannel aprt i found that the light bulbs had the common black area regular fluorenecent light have after time of use.
there are 4 of this light in the monitor two at teh bottom of teh pannel and two at the top. and they get connected to the right side of the power supply to the pink and white wires.
So when your acreen goes black doesnt mean that there is no signal, if the power light isnt flashing (which is one of the ways the monitor let you know there is no signal coming in, the other one being the message on the screen).
in my opinion you should buy a new monitor and avoid this one (shame cos it does look beautiful) even if it a gift.

I had the same problem, dead p.o.s. I enjoy this monitor, it’s one of the few on the market that are completely flat on the face. Great look! I own two, one used off ebay, repaired. Land fill, no fukin way. Found a fellow who can fix the power supply on ebay, $40.00 . I found a fix here on Fixya. Went to radio shack, better to order on line their inventory for these parts is itty *****, the same size capacitors, only $10.00. Inside in the guts of the power supply the capacitors were bulging and leaking.
Pulled them out and amateur soldering popped in the new ones, replaced 4 of the 6 big fukerz. Harest thing was getting the cover off, slight pry and slide up. And whalla! Good as new. Got 5 years on this one XG-91. Suk me Xerox for cheep o Partz! Burn the fuckerz that don’t make things to last!

Sent it for a fix no Luck, thou I dont think the guy had a clue what to do with it. Any way it cost me money.Turns out the guys a thief. He dissconnected my wires hoping I would buy a monitor from him.
Any one know where I can report peaple like this?

DONT BUY XEROX PRODUCTS!

God this company is crap like there products , they just dont work

At last I have someone else who has the same problem as me. I thought I was going mad. I have got so fed up with going through a cycle of turning it off and then on and then off......
It started with the monitor turning itself off to standby mode during the boot-up cycle. My Compaq logo would appear then the monitor would go off; the XP logo would then display and then the monitor would go off; then the XP user login screen would appear briefly before the monitor then turned off again. I found that the trick was to keep turning it off and on until you were able to load MS Word, then the monitor would stay on.
Unfortunately, I now get nothing other than the brief magic words 'NO SIGNAL'. I have tried hooking it up to my Laptop but only get the same message.
I have also heard that it could be the capacitor on the Inverter, but as my Xerox if now two years old I will have no choice but to buy a new monitor (definitely not Xerox).
I think its fair to say, STAY CLEAR OF XEROX Monitors.

This seems to be more common nowadays.
I have seen 6 HP screens suffer this & have been sent back to factory. All 15" ~ 2.5 years old & died within 3 months.
I have heard it could be a capacitor on the inverter if its any help.

I had the same problem, only my screen stayed a white color, thought it was drivers, so downloaded new ones. The problem was with the monitor, then I looked and saw my warranty (joke) was nearly up, like in 3 weeks. It took me forever to get the people at Proview Technology to get back to me, it cost me $58.00 to ship it insured ground to them, and it took them a month to return a monitor that smells moldy in a beat up box. I'm not even sure if it was my original monitor. I purchased a Staples 19" flat screen monitor with a 3-year warranty for around $200, it is the best buy I've had. I paid $398 for the Xerox monitor with a lousy 1-year warranty. They are scam artists and do treat you like dirt. I don't know how long this monitor will last, but I have it hooked up to my old pc, which I only turn on once in a while.

My monitor did that also. The turn on then off 2-3 seconds later. now it never turns on no matter how much i cycle the on and off button. Untill i unplug the monitor and blow dryed the top (has vents at the top) for about 2-3 minutes then pluged it in right away turned it on and bam! works. So yes it is with out a doubt the warm up issue. Im not turning my monitor off now since i know it will repeat the problem
Posted on Oct 03, 2007
I am also having EXACTLY the same problem with my monitor, and as you state the only solution I have found is to repeatedly turn the monitor ON/OFF till it kicks in.. Once its on, unless my PC goes into hibernation it works fine, only when i turn it off/on does it stop working. Like you state this is problably a fault with the unit as I am running of a packard bell unit running SLI 6600 GT GFX cards, which i considered to be the fault in the system till i checked them out. Im digging out my reciept and going in for a replacement unit or different model as it is REALLY annoying when you cant get an work done because you have to spend 15 minutes cycling your monitor

Warranties and customer support Xerox have the worst reputation for customer services, I ignored this advice at my cost. Faulty goods= invoked my warranty after 6 weeks old, I have waited over 4 months for my replacement, yes they collected the faulty unit, and left me with no monitor or refund. Sick of phoning and emailing, having to take a legal route with them now, so be warned. DO NOT PURCHASE XEROX MONITORS...they will treat you like dirt, liars, conmen and treat customers with 0 % respect
