Question about Philips Magnavox 51MP392H Rear Projection Television
I have an older 51" magnavox. the left side of the screen looks waved and rainbow colors not aligned. it has a very distink "wrinkle" all up the left side and it has started to wave along the bottom now and up the left side.
I bought this tv used, don't really want to pay a bunch to fix it, but i sure can't replace it. so i thought i would see what you think.
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
Where I got all my parts that worked:
Suburban Electronics http://www.suburban-elect.com/
Manual Library you should find all you need here:
What you need:
(2) STK392-120 OR STK392-150 IC chips
(12) 6.8 Ohm Metal Film resistors
set of star screw drivers
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux
BTW if you don’t plan on trying this and are going to throw out the TV, I still need a IC convergence board for a 51MP392H/17 TV I'm fixing, I'm willing to pay S/H and buy your IC board that’s not been tampered with. Edwinkraus@hotmail.com

It looks like your convergence amplifiers have gone bad, this is a common problem. If your set uses the STK329-110 or STK329-xxx series of amplifier both of them will have to be replaced. There is a lot of information on fixya about how to do this yourself, but you have to be careful in removing and replacing the amplifiers and the associated bias resistors.
I hope this helps
