The customer says after 30 min or so it emits a hi pitched squeel, or singing that hurts their ears. He said the picture "jiggles" as well sometimes. I originally thought it was ferrite cores vibrating (he didn't mention the picture jiggle part the first timE it was here) so I "damped" all ferrite cores,fly,etc with silicone. Came back with same complaint. I ran it all afternoon perfectly with the back on it. I thought meybe he saw "christmas-tree" in the horizontal, but cannot get it to act up. This Signature (PLG2767H1)is a Zenith with one large module 9-983-2. No "fish caps" found yet. Any histories on this module? Phil -- Philip Bader Jan Phyl TV Inc. (estab. 1976) 3420 Recker Hwy.
