I believe that would be the IC270 that I changed. It, is a 52 pin chip and controls all the audio, video, vertical sync etc. There is a board for the audio-video input jacks, I noticed it wasn't setting all the way down so I checked and found one of the socket pins was bent. I straightened it out and re-plugged the board. THE SET PLAYS OK NOW. I think somebody tried working on the set before it came to me. I repaired a lot of Bad solder, changed out Ic270 and replace C432 100mf @ 200v cap. But it didn't play until I found the problem I spoke of. Did I fix any thing? What was it?
