Frequently Asked Questions
Q: My TV makes a ‘tic-tic’ sound and doesn’t start; is this the part?
A: A ‘tic-tic’ sound usually means the power supply is failing to start. This could be due to a faulty STR IC or a short on the secondary side.
Q: Does this require thermal grease?
A: Yes, absolutely. Proper thermal contact with the heat sink is required to prevent the IC from overheating.
