I have an advent Q328A that I bought from best buy about in 2003. I have had
it sitting in my spare bed room since early 2004. Now I try and plug it up
to use it and I get a high pitched squeal. Any ideas what might be causing
this? It is not effect by the volume, or unplugging the video/sound cable.
It takes about 2 minutes before it starts and turns off when I turn the tv
off

short in horizontal deflection or one output of the psu or
flyback/LOPTX ...who knows? get it to a tech if unsure.

No, it sounds like the TV works still...likely 15.734 KHz squeal from
the horizontal section is my guess. Possibly the yoke is "singing" a
bit?

Ah, hadnt thought of that. If the set is Ok, it is probaly something
vibrating in sympathy with the horizontal frequency - some coil with a
loose core near the LOPTX, say.

Or something is self-oscillating because there's excessive rust... or
something damaged by heat or humidity.
