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

Xerox XG-91D 19 in. Flat Panel LCD Monitor

\015 Hello, recently my Xerox 19-inch LCD Monitor screen just went black. When I power it up the blue power light will be solid for approx. 5 secs and the screen will light up greyish-black, then the screen loses all light and the power LED flashes. I think it's a communication problem or something? I'm trying to remove the rear case to check the inside, but I actually can't figure out how to remove the case! I removed the base and took out two screws from the back of the unit, but don't know where to go from here. I notice 4 female screw ends into the rear center of the monitor, but I'm not sure if they're a part of the removal or not. Thanks for any help you can give me!\015\012\015\012Problem not resolved\015

Hey rg213 I had a similar problem with my screen over the past week. This is "solution" is annoying but has been 100% effective every time I wish to use the monitor.

After your computer has started to boot and the Xerox logo flashes continually, reach around to the back of the monitor where your power supply plugs in. Slowly, and carefully start to pull out the power cord from the monitor until the screen lights up a bright white. Let it sit there for approximately 4 seconds then completely unplug, and replug the power cord back into the screen.

I should note that when you're pulling out the plug from the back of the monitor the screen will not light up until the plug is about 3/4 of the way out of it's socket. You should also be very quick when plugging the cord back into the monitor. If you wait anymore than 5 seconds (In my experience) the monitor won't power on.

This leads me to believe that it's actually our power supplies that are going bad and that maybe by buying new ones it will completely resolve our issue. Alas, a new power supply is not in a college students budget. I hope my unorthodox solution works for you :)
I concur replacing the bulging 470uf's and 220uf's on the psu pcb does the trick, when your xa7-19i 's blue power led flashes intermittantly on powerup, you can imagine can't u the psu feedback circuit going u good? no! ok! u good? no! ok! etc
The caps in the output of a smpsu have to have a high ERS rating or something ie they are dealing with pulses of power and it wears them out :-) They get hot and sweat......
