Stupid tv!


Sounds power supply board is bad in your TV and most probably replacement of all electrolytic capacitors in power supply board will solve the issue.
Take TV to local TV repair shop for repair.

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.
