Advent tv
in [Repair]

From: Theodore B Bowen II on 28 Jun 2005 17:00 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

Possibly the yoke is "singing" a bit? Tom

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. I.
