Green power light blinks

I keep my apartment quite cold at night (about 55 Fahrenheit) and mine won't display when cold. It just sits there blinking its green LED every 3 to 7 seconds. After I have turned the apartment's heat up (67) the monitor will display an image when it reaches the new room temp. Weird huh? It seems like the LCD needs a minimum temperature to operate. BTW: My LCD is about 2 1/2 years old.

So it sounds as if the monitor is not getting a strong signal and keeps reseting. Is your spare monitor a LCD or CRT?

open it up... whats the worst that could happen... see if the caps are fine... if they are bloated exchange them... if you need help doing so hit me up at abelino24(at)sbcglobal(.)net... I've repaired like three of these in the past few months.. its always the capacitors. they either get really hot and bloat or don't function if it gets too cold... so the solution if to get the right caps at 470uf / 25v and 220uf / 25v... hopes this helps...

These XeroX screens were made with a bad screen power supply screen, there are a 2 dc/dc converters for screen illumination, as they get hot, they don't work, and they get real hot soon, this was a really bad design, because this converter driver are a small SO-8 mosfets N and P in a single chip, and they are unable to handle that power for long, sometimes they go half way bad and you only see half screen illuminated, sometimes they both go bad and and there is not illumination at all on the screen, and sometimes they get hot and power suppy goes to protection and the blue light blinks till mosfets cools down, I had a few this monitors fixed in my repair shop and they kept coming back till I found a way to mount a heatsink on top of this mosfets....
