It sounds like one of the convergence Ic chips is bad---you will need to locate and replace both of them and look for any damaged parts around them; there usually are two pico fuses in this area, one for each IC. The fuses do not look like glass fuses--they usually are green or orange in color and will have the amperage marked on them and on the top of the circuit board.
A lot of times when the convergence ICs blow, there are also problems
with resistors on the board (talking from Hitachi experience), or the
If the other problems, like blown resistors, are not repaired, the ICs
will blow again right away. If the ICs are your only problem, then
replacing them may work http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html
