A friend of mine has a Philips 9P6031 C102 big screen TV in his basement, and the convergence is shot. I'm trying to find out what parts he'll need for it, but Google has failed me. Maybe somebody here can point me in the right direction?

There's a good chance that it needs the STK IC's on the convergence board replaced. There are also some low ohm fusible resistors that have probably opened when the IC's failed. Don't buy the cheap Chinese knock-off IC's that are sold by various parts houses. They will likely fail in a short time and cause more damage than what you had to begin with. You should be able to get the originals from Tritronics or MCM.

I mainly need to know what STK number to get.

It probably came with STK392-120 chips from the factory. I would use -150, or -180. Even better, order kit X480293 (about $35.00) from someone that sells Hitachi parts. The kit has 2 STK394-160 chips, which are even better. It also has a handfull of resistors, which may help you if the resistors on the board fried. If memory serves me correctly, the resistors that fail are usually 6.8 ohm, and grouped in sets of 2 in parallel, making 3.4 ohms. I have used 3.3 ohm in place of the two 6.8 and the convergence only needs a slight touch-up.

Be sure to get the heat sinks clean and shiny, then put a thin film of heat sink compound on the IC's. Those chips run pretty hot

Okay I have this TV's convergence board. It has two STK392-110 IC's on it.

My plan is to order two new STK392-110 IC's, as well as test all the resistors. I think the caps are okay, as they're all Nichicons, but I'll test a few of them as well.

Good luck.... If the caps are bad and need replacing, you may need to set it up again, which as we all know can be quite a hassle.

I've yet to see a failed Nichicon, especally in a TV that's really only seen a few years of use.

Still, I AM going to check the ones by the IC's. None of them look like they've seen any real heat though.
