Replaced stk's only worked for 10 minutes

Hi,

This is my first real TV repair, and so far I'm enjoying it-- except the whole not working thing... Meh, Details...

I did some searching in the forums but couldn't find anything that quite fit what I'm experiencing. I replaced the two STK392-110s in a Panasonic PT-47WX53G after experiencing convergence issues. It was better than ever for about 10 minutes and then upon switching to an HD channel the issues returned. Now it's worse than before.

Oh and before you ask. Yes, the layer or heat sink compound I put on them was a work of art. Nice and thick (but not too thick) and perfectly even, so if they burnt up there's something more sinister going on than just that.

I've read a bit about Pico Fuses, and Resistors but wanted to make sure it wasn't an even bigger problem like some kind of power management malfunction before I spent any more time crouched inside of this thing.

I guess I'll just keep beating it with this foam Nerf sword... See if that helps.

Thanks!
