A nice little Control IC but when they fail ithey take out a lot of components around the power supply especially the output FET rather catastrophically for the power board.
I would look elsewhere for your fault because if there is a flashing light, the microprocessor has power and that comes from the power supply.
Look for open circuit fuseable links.
Hope that helps.

Did you check if 24v supply is coming to the chip ( through a fusable 10 ohm resistor ) ?.Look for dry solder on the sync chip ( 24 pin or 40 pin IC ).

Can you please check for any jammed buttons on the remote and/or control panel? Try switching on the TV manually, while removing the batteries from the remote. If you notice same problem, the area to be looked into is around the system control area: like dry solder, leaky/dry capacitors and this should be done only by a qualified service technician.
