Check that the fans are working correctly.
If a fan that cools the lamp is not working then the Lamp light will blink.
Have you checked capacitors on power supply board of TV and did you find any leaky/ bulged/ swollen capacitors on power board?
I understand, there are few other supplies on power board, did you test those volts?
OK, power supply board provides 16V, 6V, 12V and standby 5V supplies. Please check these volts to confirm they are available and constant.
You can check these volts at connector CN811 of power supply board as pin configuration would be stamped near the connector for expected volts on each pin of connector.
Sure, please find attached picture of CN811 connector pin configuration which will help to check volts for each pin.
