You will need two STK392-560 Convergence ICs and you will also need two of the 3.5 amp pico fuses as Sonys will always blow at least two of the Pico fuses. You can get replacement ICs and Pico fuses at the fiollowing link and they provide free instalation instructions. Heres the link.

SOURCE: Front panel buttons and remote have stopped working.
Is the favorite channel menu a function that is normally accessed by a button on the remote?
If so, that button on the remote might be stuck.
If this is the case, the menu may at times pop up all by itself and other buttons on the remote and on the TV's front panel may not respond at all (it had happened on my remotes more than once).
Try to clean the remote control (the housing, rubber pad with knobs, circuit board) with ethyl alcohol, when you clean the housing, you should also clean the holes through which the buttons protrude, there might be some dirt that keeps the button stuck.
It may also be a stuck button on the TV front panel, so check these too.
Also, it could be something else, i just wrote the description of a problem and the solution which to me seemed most likely.
Hope you get it fixed.
