Sony KP 53S65 Rear Projection TV

You have a bad capacitor, its location number is c514, and it is located near the horizontal output transistor. i just finished 2 of these sets, the cap values are 390pf @ 2kv. best of luck to you.

I don't know if this will help you but I just experienced a similiar problem with a sony kp-53s35.
It turns out that a fluid leaked out of a rubber boot on one of the guns( I have no idea what the fluid is or why it is corrosive), down to a circuit board and started to desolve a jumper wire. when it had eaten away enough of the wire, the residue or solution was conductive enough to cause an arc to a ground bus bar that ran along the circuit board. The TV still worked but would crack and pop like firecrackers inside.
I was able to increase the distance to the ground source by bending the bar away. Then I scraped and scrubbed the board with contact cleaner to remove residue and replaced jumper wire.
Has worked fine since.

Did you get this TV repaired? What was the cost of the repair? My neighbor has the same tv with the exact same problem. Before calling a technician, I'm trying to find out if they should just scrap it and buy a new tv. Thanks for any help.

The unit has a bad crt Itis a known problem Callsony to see if they will authorize a part coverage on the crt
