TV made a very loud snapping noise and promptly died. Took it apart and found one little resistor on the power supply board was blown to bits. Hopefully I can just get someone to tell me which resistor, capacitor, or whatever it is I need and solder a new one on, but since this one is blown to bits, I don't know which one I need. What I do know is that this is a Sony "G" power supply board and the number on the board where the resistor is blown is (C613). Am I possibly wasting my time only to watch the resistor blow again, or is this just a simple defect in the cold solder that I can fix myself?

Re: resistor on power supply board
First, first C613 means that it is a capacitor, not a resistor.And It seems to be a electrolytic Capacitor.If it has burst, then it's can will be inside. just search. the details of the Capacitor will be on it. most likely it will be a 10mfd 160V capacitor. Check and replace.

ZD3 is a 18v zener. Also check the surface mount resistor on the back of the board that is attached to ZD3, I think it is R9. Should be 10 ohms. This resistor sometimes opens when the diode goes short.
Tv power supply board it is causes and the problems.That the board where the tv power a/c cord plug into it.Take the tv aparts,check the tv power supply board carefully for dying and leaking capacitors components parts.These dying and leaking capacitors components parts are alway bulges ups or puffing ups onto it tops.U have all the tools and know basic electronic?Yes,than u must changes all these dying and leakages capacitors components parts are bulges ups or puffing ups onto it tops.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish tv power supply board for the replacement.As soon as the tv have a stable power supply board is it alway supply correctly voltages and current to the tv.These clicking noises will stops as tv turn on or the tv putting on standy power.

I assume it was the power supply that you replaced? It is very likely that a fusible device on another board has gone open circuit to protect any damage due to the initial problem. Again I assume you have a plasma TV in which case there will probably be a problem on the Y or Z sustain boards which may also need to be replaced as this may have been the reason for the other board to burn up
