    Do you hear a chirping sound?

    Which board did you replace before? Was it for the same problem or a different issue?

I hate to say this, but this is why I've been trying to tell people here not to fix these sets. This is EXACTLY why I don't repair Magnovox any more. They just don't hold up to repairs. Those sets can have a bad small signal board or a power/deflection board. I'm sorry your having problems. Sound like the power/deflection board is working since you say it powers up. Some of those sets have a "daughter board" that plugs in on edge of the signal board "SSB" that go bad all the time. All the video and sound go through it. Just cut your losses and don't spend any more money on it. I hope it's something simple for you, but I'm affaid it won't. Good-luck.

    If that is a 64P8342, the part# for an SSB moduel is 3139 127 25871 and cost around $200.00 or more. VERY common failure part. This will cause exactly what you describe. Will also cause all sorts of funky systoms as well.

If the lamps have been ruled out then it MAY be the Ballast that powers the lamp, no easy way short of replacement of that board to know, You might want to contact Sony to see if this is a known issue in their database for this model.

I have a Phillips magnavox P960349102 model#PTV835. I have power no picture or sound. How do I fix this?


Have power/deflection board rebuilt. Probably will not last long from my experience. In reality this model is too old for a good, reliable fix (like CTC167 in RCA is too old for a good fix, and Hitachi pincushion circuits).

PHILIPS 60P8341 PROJECTION TV NO PIC NO SOUND


Thats the DPTV 300 series phillips HDTV its definatly worth fixing. How are your troubleshooting skills. Sounds like either a problem in the LSB or SSB circuits boards. On our website we have replacment circuit boards for that model. Our prices are less than half what others are getting. Let me know if you would like me to post a link, we also have the service manual for your model.
