monitor flickers and dies in cold
The cost to repair is going to likely be very close to replacement cost of a
low end 17" monitor. I see many 17" monitors on sale new for under $90 all the time. $200-$300 will get you a top of the line flat screen (not LCD) 17" monitor. David Rob wrote in message m... Just recently my 4-year-old 17" Relisys TE786 monitor has started acting up. The picture would randomly just flicker off and on to a black screen. It took me a while, but I think I've discovered that it does this when the air conditioning is on. As the room and monitor get colder, it flickers on and off more, finally it gets to a point where it the pictures flicks off and doesn't come back on, even though the monitor is still getting power. Eventually, the picture goes black, then it clicks a few times and I get a white screen with vertical bars which usually means the monitor isn't getting input. I wanted to change the VGA cable, but it's soldered inside the monitor; it doesnt' just simply unplug. So I assume I either have a faulty cable, or a cold-sensitive part inside my monitor. Is this going to be something expensive to repair? People in another group told me it'd be cheaper to get a new monitor, but I can't really afford two or three hundred dollars for a new monitor at this point. Thanks for any advice, Rob |

It could well be a cold solder joint. But, unless you really, Really, REALLY, *REALLY* know in your heart-of-hearts that you're "qualified" to open it up and attempt the repair -- _don't even try!_ Over the years I've located and repaired several cold solder joints in (various brands of) monitors here on my own home lan.
