Hello,

I have a LG TV, The model is: "Cf-21d52ex".

Unfortunately the TV standby LED just blinks when I turn the TV on and I have no AV, Just have LED blinking.
Can you guys help me out to realize whats the problem on the TV?

Thanks.

could it be an lcd????have a look at the smps and you will find(depending on model)split domed capacitors-several may need replacement ,if its the set im thinking of replace them with hi temp types rated at 25v dc(the two supplys affected are the 5v supply and 12v supply

That's a big inference to make from a blinking LED on a TV

Sad... So sad... Given the failure rate I'm really surprised more though isn't put into PSU designs.. Even with the added cost, I personally would eagerly put up the extra cash for the higher reliability.

Yes I found that the problem is a 100uF 16V capacitor on power supply unit.
I found the problem by a hairdryer lol.

What ESR does mean?
