Hey I've been working on a Sharp LC-C5255U
Symptoms were, once plugged in only the green LED light starts blinking continuously. If the power button is held down for 5 seconds the green led turns red.
Then Press the power button again, red led turns orange, and the TV would turn on (backlights on) for about 2-3 seconds and shut back off and the starts the green blinking LED again.
Opened up the TV to the CCFLs and found that one of them was not lighting on. Switched two of the lamps, but the same initial position did not light on, so the CCFL's are actually good.
I switched the ballast caps to compare the ccfls but no change.
Switched the transformers and what do you know! the position of the CCFL that is off also switched, so concluding a bad Transformer on the inverter board.
So heres the question, I'm guessing its pretty hard to find an exact transformer component to replace so thinking of other options. Is there a way to bypass the transformer like i've seen with the lnt-4066f samsung lcd tv by jumping a wire where the bad transformer is?
