Hello,

I have a ~6 year old Sony CRT tv and recently it started giving me
problems. About a month to two months ago it started to shut off
after a dew seconds of turning on. I left unplugged for a while and
it worked normally again. Recently it started to happen again. This
time, it won't stop shutting off. It is always a few seconds after I
turn it on. The picture doesn't show, but sound does. I have tried
to leave it off for ~24 hours.

I read on the web somewhere that it could be a dust problem. They
said to leave it off for a few hours and then try to remove the dust
around the large cable going into the tube. I tried that, with no
results.

I have been looking other places and read that it might be a HV
problem. I am a ME grad student and have a little experience with
electrical systems. I would like to get it fixed rather than buying a
new one because of my tight budget. Does anyone know what the problem
could be and if it would be reasonable for me to try to fix it? Or
should I hire a technician? Or is it not even worth doing that (too
costly)? I most likely have access to all the equipment needed to
test it. Thanks

Jeff
