Hi guys...

Wonder if one of you might have experienced this before;
kinda point me in the right direction.

Magnavox (Phillips) monitor. Has developed a bad habit -
have to turn it on several times before video will appear.
Power comes up (led stops blinking); and I can hear a hint
of high voltage, but no video.

After several turning off and on's of the computer it will
start, but is quickly getting worse. Now if I shut it down
I have to wait several hours for it to cool down before I
have a hope of starting it again.

I have several monitors, but this is the only one that plays
nicely with my all in wonder card.

Anyone run into this before? I'm thinking caps, but have
no esr meter. Could wholesale change them out, but...

Thanks in advance for any tips.

Ken

Model number?

I suspect it's a capacitor, either that or a solder joint. A can of freeze
spray will probably be your best bet, start around the power supply, let it
warm up so it's working, then freeze a small section at a time, don't frost
the hell out of it, just give it a quick spurt and cycle the power until you
find the one that makes it misbehave.

If you hear a crackle of high voltage but no picture it may be a PSU problem
as the first poster suggested or I think a good candidate would be a bad
solder joint on the CRT heater pins.

Hi...

Thanks very much to everyone who replied. Appreciated.

Unfortunately the monitor must have noticed I was writing
you guys... and got scared.

Took the durned thing apart, prepared to flow a bit of solder,
change a few caps on general principle, maybe do a little
percussive maintenance while it was running...

But ever since, it's worked flawlessly

Thanks again.
