Question about Xerox XA7-192i 19" LCD Monitor
My xerox screen is just over 12 months old and has not had any prior problems. However now when i boot up my computer the screen is all white. If i turn the screen off and on again the xerox logo is displayed for less than a second and the screen goes white again??? Occaisionaly the auto button will bring everything back and it's fine again untill i turn the computer on again. Please Help!!
I had the same problem but fortunately I have two of these monitors so could fiddle with the menus on the working monitor until I could work out how to fix it on the one with the white screen problem. Here's what you do:-
With the monitor on and the white screen showing press MENU, then UP 7 times, then MENU and presto! Your screen will be back to normal.
What this does is change the input from ANALOG to DIGITAL (or vice versa!) either way this worked for me.

I have resolved this problem by replacing 6 x 470uF 25V and 1 x 220uF 25V radial electrolytic capacitors on the power supply board inside the monitor casing.
DISCONNECT FROM THE MAINS BEFORE ATTEMPTING ANY INTERNAL REPAIRS!
1] Remove single large screw holding elliptical foot to case.
2] Remove 2 x small cross headed screws at bottom of case at rear.
3] Sit monitor with rear of case on your lap and push firmly on the bottom edge of the glass screen (the edge with buttons on it). It is a tough job but eventually the plastic retaining pegs click free and you can slide the glass screen away from the monitor screen itself. TAKE CARE NOT TO PUT FINGER MARKS ON LCD SCREEN FRONT!
4] Remove 6 screws around edge of LCD screen frame holding LCD frame to case body.
5] Carefully lift using edge of LCD frame the LCD screen away from the case body and you will see 2 pairs of white plugs and sockets feeding the LCD and 1 large multi-way plug on a braided screened cable (covered by self-adhesive aluminium foil).
6] Using a marker pen (small tip size!) mark each white plug and socket so that you can replace each plug into its original socket when you have to re-assemble things!
7] CAREFULLY peel back the aluminium foil and gently, but firmly pull the multi-way connector out of its socket.
8] Place complete LCD screen in a SAFE PLACE!
9] Looking into case body you'll see a metal box cover. Remove screws to enable cover plate to be lifted off. Reveals psu and other electronics PCB.
10] Remove 4 cross headed screws holding small psu PCB in place and lift away. Note small PCB mounted plug/socket along one edge.
11] Locate and replace the 6 x 470uf and 1 x 220uF capacitors.
12] Reassemble in reverse order.
Voila, a working monitor! Total cost to me here in the UK was £2.61 including postage for parts!
Hope this helps anyone else with similar white screen problems!

A HP Pavilion had the same white screen problem. You can determine whether it is the computer or the monitor by connecting a known good monitor to the computer to see if the monitor works. If you have another known good vga cable, I would use that also in the test. As it turned out, the other known-good monitor worked and the HP did not. I am inclined to believe that as others have written that this is a hardware problem not easily fixed and it's cheaper to buy a new monitor.

Sadly this fix did not work for me, even after replacing the large 100uF 400V cap and the 47uF cap next to it in addition to the others! Any one got a spare backlight??
What may help others trying this fix is that when you come to remove the glass front after removing the two screws at the back it is much easier to lay the unit on its back with the bottom facing you. Then, whilst gently pushing the glass bottom, use a flat bladed screwdriver to prise the back cover downwards 1 - 2 mm at the centre. The glass will then slide up easily for removal.
Thanks anyway for the fix, and good luck to anyone else trying it.

I also have the same issue, Sad but I'm happy its fixable I kind of liked this monitor. But then again it was my only monitor I know no different.

Recommendation : never buy a xerox product ever again

I bought capacitors from maplin but they didn't have 25v - the assistant said they had 35v and this would be fine. put them in but becuase they are bigger the circuit board wont slot back into the plug - the top of the capacitors stick out too much with the bigger size... so need to find a smaller size

I have struggled with the same problem for weeks. I eventually found a site where the concensus was that it was a hardware failure and it would be cheaper to replace than fix. PC World help desk concurred and said that this kind of failure is not limited to Xerox screens.
I replaced it and the new screen works pefectly (so not an adapter / driver problem).
Not really what you all want to hear I know, but....
