Tv was dead no vvidei no sound after checking found that power supply capacitor and horizontal deflection output transistor was defective i lost that tr no part no please tell me what should i do?


Hello
There are few models of Sony telivisions which uses transistors in vertical output section. It will be a matched pair of PNP and NPN transistors. According to Sony schematic which I have with me used 2SB6494(PNP) AND 2SD669A(NPN) as vertical outputs and 2SC2383 as vertical drive, 2SC1364 as vertical oscillator. Just try to get the orginal numbers or find its equivalents from data book. Ok.

Sony KP 53S65 Rear Projection TV


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 solution1.gif 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.

Standby timer light blinking, tv will not turn on


Check out Ceramic Capacitor C514 by the horiz. output transistor (burned/shorted?) My question is how do you find the specs of the capacitor and where do you buy one?
