Re: xerox xa7 19" lcd monitor

That means that you have a defective inverter board.

The inverter is a small power board that power up the LCD backlight lamp, determining light intensity, when it is like that, the inverter is defective and must be replaced.

When I power off my LCD monitor, the screen goes all white, but once I turn the monitor back on it goes right back to displaying whatever it should on the screen. Or when I shutdown the computer it also...

If this has happened to two monitors on the same computer, then i dont think the problem is with monitors, i think the problem is with the graphics on the computer, i suggest uninstalling the driver for the graphics card in device manager and then restart the pc to see if that makes any difference. The divice manager in in the properties of my computer icon, just right click and choose properties, then device manager.

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 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!

White screen on xerox xa7 19i

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.

Screen goes blank also.

I too have an LCD Xerox - it worked fine for a while, then kept going blank and going onto standby. Unplugging and reconnecting from both pc and power seems to reset it. It hadn't happened for months but started again the other night when it occurred to me that I had just downloaded MS security updates - I've removed the ones that I downloaded just before it started happening again and the problem seems to be solved. Hope this helps someone.

Lacie 19" Electron Blue - Black screen with a brilliant white line across

I have 2 of these monitors and have this problem. I was so frustrated turning the monitor off and on until the white line disappeared that one day, I punched the screen. And it worked! So now whenever this happens (about once every other day) I use my palm and smack the lower left corner of the monitor until the white line disappears. I like the color on these screens so I don't want to replace them until I have to. I will NOT buy another Lacie though.
