Question about Philips Magnavox 51MP392H Rear Projection Television

2 Answers

Magnavox 51mp392H/17 All the print is doubled and there is a rainbow of green and red at the bottom of the screen. I tried to adjust the convergence manually with no success. I saw in another listing that it could possibly be this part stk392-150 but when I looked it up it was a semiconductor. Could it be a convergence amp. and if so what is the part number.

    Is it hard to change the convergence on the 51mp392h? What tools will I need? Where can I buy the parts at reasonable priced? Thanks for any help

    My screen tends to get green lines across it and an arc of colors at the bottom. Adjusting convergence did nothing. I was told by a local repair shop that it would take $300-$350 to repair, but they didn't tell me what the problem was. Is this something I could fix myself for less?

    Magnavox rear projection screen TV model #51MP392H/17 has red convergence problem. I can manually move the red convergence left and right but not up and down. I have already installed the new convergence amplifiers #STK392-120 and still not any better. What,where and how do I check for another problem and how do I fix this problem. Thanks for your time

Yes,semiconductors is the term used to describe transistors,diodes,intergrated circuits(IC's)etc...the correct generic part# for that model is STK392-120 which is an intergrated circuit (IC)which in that TV works as a convergence amplifier.The specific Philips part# is 932212344682. There are two of them you need to change both. Also check the two 6.8 ohm resistors nearby if they are burnt or discolored.

Magnavox tv model 51mp392h/17 words on the bottom are double one set is red other set is green

Thats caused by failed convergence ICs and the 6.8 ohm resistors. You can get the repair kit called the DPTV305 -DPTV345 & MAG01 chassis convergence repair kit which fits your model. The kit has the components and the CD with repair instructions and its available at the following link top of the page.

My screen has a wave in it/red convergence won't adjust

You have convergence output failure. The output ICs will need to be replaced and possibly a small component like a resistor or two as well. Expect to pay a service company $350-$450 to resolve this.
