Hello,This sounds like a capacitor malfunction. Check the capacitors on your power supply boards (there should be two of them one is the AC input board and the other is the main DC switching powersupply). I have seen this before and every time it has been a series of dried out and bloated capacitors, effecting voltage regulation.Check for bloated capacitors and replace them, then check the voltages at the test points to make sure they are within specifications.You will need a multimeter, and the schematic for this TV set.I hope this helpsThank you,Shuttle83http://www.electron-age-technologies-llc.com

I bought my 46" samsung


The Capacitors on the Main Power PCB are failing which is why it's taking 3 attempts for them to charge before the TV will switch on.

These could be replaced for a few $ if you know someone with the technical ability and equipment.

Failing this it would require a new PCB at around $120 + fitting.

Will not turn on just clicks and red light off and on


The cycle clicking comes by following reasons:
Power supply defective.
Mainboard defective.
Other boards defective. TV needs to check to isolate correct problem.
As far as I see, the 46" LCD has common problem of the power supply.
