Hi,
Sounds like there is a short on the power board or the power board has gone faulty.
Look on the power board to see if any of the capacitors are bulged or if there are any other components burnt out.
The TV is going into protect mode because of an over current, which points to a short on the board or a component has gone short circuit.
Thanks

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.
To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

Hi,
There is a power fault with one of the PCB's inside, contact Sony if you are still in warranty, if not contact a Sony service center as it will need an engineer to open it up to repair it.
Thanks

it sounds like your back light might be going out. You might be able to fix this by installing a new backlight inverter board.
