Hello,

I'm not a TV expert unfortunately, but I do know some electronics from my job. I would be grateful to anybody that could think of what could be causing the trouble below;

My RCA 169PEB chassis went down due to a blown H.O.T. and a burned HV splitter. I ordered the repair kit (CTC169-KIT-PTV from Tritronics) and replaced the parts. It powers on now and B+ is about

142V. I get an image and sound, but the screen seems to vibrate and horizontal lines are seen. Also, the sound seemed to mute itself after set being turned on for a few minutes. comes back on when I turn volume up or down.

I thought perhaps an experienced technician has seen this before and could point me in the right direction.

Thanks

Thad

Go over the solder joints - they may have caused or contributed to the original failure!

If it was made with lead free solder, the joints will all look "dry" anyway - look for a sort of grey/brown ring round any of the solder fillets (as well as obviously cracked ones!).
