Question about Sony KP-43T70 43" Rear Projection Television
Oi? You mean thermal grease? No thats not the source of the problem in fact I think your problem is not related to the ICs itself. I suspect that you have bad capacitors in the convergence or deflection circuits that have to be replaced? If you are handy at working on electronics I suggest you take a look near the heatsinks(where the ICs are) for capacitors that are bulged or cracked at the tops. If you find any then they will have be replaced with those of exactly the same specs. That should do the trick.
