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).

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.

sorry. Hope you still have a waranty. This is not an uncommon problem with the sony's. 99% chance that the panel went out. Could also be a balance board issue, but usually not. Call Sony for an authorized repair center
