I have a little problem with my laptop. When I try to switch on it after any
cool nihgt it runs on ~2 sec and automatically switchs off. What is the

Thanks

Hello, Looking to get my favorite monitor back up and working away again.
I had been using it non stop for a few years, and just before I had to move,
I went through a period of about a week where after it would be on for maybe
an hour, the blue gun or signal would just drop out. I ...

Ok, I was pissed. A roof leak dripped right into the slots on my
Prinston EO500 while it was on, in standby. When I discovered it, the
screen was compressed and severely distorted. It was clearly in dire

Anyone have any suggestions for repair or info about this system that

Good evening,
My son has my old 98 GMC  pickup with the "standard AM/FM Cassette
player radio which was a factory install. Most of the buton lights
have burned out and he is trying to get at them to replace them. I

This set will not power up. When you first plug it in the led blinks 10
times, then the relay clicks and holds for 10 seconds and then clicks
again. Then the led blinks 4 times. Thereafter as long as its plugged
it does a repeating sequence of 4 blinks. Trying to turn it on during

A lot of nice radio/test/computer equipment from the late 70's through
the 80's and even the early 90's had the "feature" of battery-backed-up
configuration settings. Often this was done thorugh NiCads soldered to
the PC board (often in those little plastic modules). Over the years,
