Question about Philips Magnavox 51MP392H Rear Projection Television

1 Answer

Magnavox 55'' Projection - Sides come in and out

When I first turn it on for about 20 minutes the sides cycle in and out, about 1 per second, about 6 inches in. Oddly, it especially happens with white or light images, but a dark image will stop it. After about 20 minutes of use, it stops. I'm guessing it is some sort of power supply regulator, or convergence issue.

Sounds like Convergence issue.... I have some pictures of the bowing picture TV on the link below...

I'll post you my general message which is for a similar Philips Magnavox 51 inch TV, you'll need to check the manual verify the correct IC convergence chips and resistors, the manual link is below as well... usally the IC's are STK392-120's or 150's and the resistors are 6.8 ohm 12 of then...

anyway read the general post below it will get you headed in the right direction.

51MP392H/17

Actually I have this TV and you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted
pictures on, check out page 3

Turning off by itself


This TV probably needs the convergence amp IC's replaced. When they go bad the TV will not turn on.Call a good TV Tech and tell him you want the IC's upgraded to STK 392-150 instead of the original STK 392-120 and check all resistors in the circuit for proper value. They could be burned or open.
