As long as the part number for the power supply is the same, yes you can. the thing is that even though if they look alike it might not work, that's why you need to check to part number, remember, they need to be the same one... you'll be able to findit on the back of your power supply

Power light blinks 3 times but it does not come on


Thats caused by issues on the deflection board. It can be the power caps CP150, CP120 and CP114 or it could also be the Flyback and HOT tarnsistor or several other items all located on the deflection board. Often its easiest to just replace the deflection board on that model. You can get the deflection board from www.tvcircuitboards.com

My r61wh76 does not turn on. what could be the problem


With that model its common for the Deflection board to be the problem when it doesnt power up. It can be the Power caps, Flyback transformer or several other items all located on the deflection board, so its usually best to replace the deflection board . You can get the deflection board PSB-260 from www.tvrepairworld.com which comes with installation instructions.

Sounds like bad capacitors in the power supply. check for bulging caps or replace the power supply

Replaced convergence board, fixed problem, and now want spare.


The usual order of probability I have found is:

Semiconductors
Electrolytic caps
Regular caps
resistors
inductors/trnasformers

Static testing OFTEN will not reveaal the failure.

Power light blinks - and now the TV won't come on


Most likely the power supply and/or related circuitry has failed.

RCA P61960 projection screen. no picture, no sound. tries but shuts off.


It will depend on the Chassis number you have but it sounds like a bad Deflection module or a bad Convergence power supply module. The Convergence Power supply module is on the left looking from the back mounted above the deflection module. On newer models the picture tubes can short and put these sets into shut down mode ( Three Trys). Start by unplugging the CRT modules off the neck of the tubes one at a time. If it doesn't come on you have eliminated the tubes. There will be a Red and Black set of wires from the deflection module to the convergence power supply module. Unplug it. If it fires up then it's the convergence power supply module. If not it will probably be the deflection module. The flayback transformer is a common problem along with several bad caps towards the front of the board. Let me know if this fixes it.
