Union Electronics, near Chicago, also has them, the version they use has an extremely low failure rate, unlike those of some other suppliers, which are much less expensive, but not as reliable. My guy there has been very good with whatever parts I have needed.

I have alot of offset blue and yellow in my picture. I tried convergence from the front but it didn't help...what can I do to fix w/o alot of cost in these tough times..?


Hi,
This problem is related to the convergence, but it requires replacement of IC STK from one of them who control convergence, check both and replace faulty IC STK from new one and your tv work fine again. You can buy the convergence IC's from the link click here.
Thanks for using fixya.

After replaced stk IC's, check if any resistor look brown or born, if yes, replaced it with 6.8 Ohms. If you have questions? noetvs@embarqmail.com . Good Luck !!

What is the correct part number?


The question is old, but this might still help someone.

I had to replace mine on the 55" model, and I went with the STK 392-150's. The cause of failure is normally overheating, and with mine they did a lousy job of applying thermal paste to the backs of the ICs. (as you can see in the pic, so I'm sure that is why they failed). Depending on where you buy them, you can probably find the 150s or 180s online for the same or lower price anyway, so go with the higher power rating since that means they will likely withstand more heat for longer. But make sure you buy a good thermal paste and apply it evenly and correctly. Mine is working great now going on 3 months, I used Tuniq TX-4 paste. BTW, I'm a lousy solderer but I removed the old and soldered-on the new chips by hand. It looked pretty rough but ended up working perfectly. Anyone can do it!
