I read your post and I wanted to know if you did it yourself. I opened the tv and it doesn't seem possible to do by myself. I am also having dificulties finding the smart power IC F9222L. Can you help, please?

first off mike, dont worry about breaking the glass.. its thick and very strong.. second, yes its the capacitors and i called a shop and they wanted somewhere in the neighbourhood of 100$ just to look at it.. i just finished replacing all the capacitors on the board for 30$ for parts and another 30$ for tools (desoldering iron, soldering iron). I put the TV back together and it works like new, so if you can find the capacitors, swap them out yourself, it will save you big money
It sounds to me that you may have a power supple problem. There is not an easy fix for it. From different sets I have fixed with similiar problems, I found that the start up transistor and start up transformers may be bad. Although there are ,many possibilities, you'rs sounds familiar with sets we get in every day. If you are going to work on the set yourself, start at the strat up transistor and go from there.
