Question about Philips Magnavox 42MF521D/37 Television

1 Answer

Magnavox 42mf231d Ok well i'm part of a large group of disgruntled consumers who purchased this plasma TV. Bought at Home Depot in 06 for $1400. It died last night. Have sound but no picture. Spent the evening reading hundreds of other peoples postings on having the same problem. Also found out there is a class action suit against Magnavox for this problem. So I called them and got the run around. Out of warrenty not our problem. Talked to some phone jockey and got nowhere. Said no recall is in the works. He said that there were no service centers near Philadelphia. And that there was nothing he could do to help me. I even offered to send it to him to get fixed and he said they couldn't fix it! If they can't fix it who can? Told him I have always owned a Magnavox but will never again! I have found alot of people talking about replacing burnt out capacitors on the power supply. I would like to find more info about replacing them and if it works or not.

You may have a weak power supply. This would indicate one or two capacitors that are weak or bad. This model may be about 4 years now and this is a good indicator as these capacitors need replacing. The other problem may be the infared board in the TV that receives the signal from the remote may be a problem as well. I would certainly investigate my first thought. The latter is kind of rare. Thanks for asking and show a few hands of support.

My Magnavox 42" plasma TV purchased from Home Depot also went out last night.....No picture only audio. What a shame! looking for a posible solution


power supply board - check the fuses first --- remove all cords and power cord -- wait one day then connect -- if this doesnt work -- you probably need a new power supply board without looking at it - can order online at partstore.com
