Re: tv has soun but no picture


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 my parts that worked:
Suburban Electronics
Manual Library you should find all you need here:

What you need:
(2) STK392-120 OR STK392-150 IC
(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.

Hello, all of a sudden the tv made a fizz out sound

Souns like bad HV transformer. Remove thedeflection board and send it to PTS for rebuild. At this point there are also other components that have failed.
