Have TV Questions? Ask a TV Technician
Hello, and sorry you're having problem. This issue is not a synchronizing problem per se- the clicking is caused by the Mainboard, which sends the turn on command to the power supply board. It's a hardware failure on the Mainboard that causes this. I assume you're looking to repair the set yourself?
If so, there's two options. Since the Mainboard is very rare, the only source I can find it showing in stock is around $175 (link below):
Alternatively, there is a repair service that will repair the board for closer to $55, and if you're comfortable removing the part and sending it out, then you can send it out to the link below for repairs:
If you need further assistance let me know. Please do not forget to click at least a 3 STAR RATING, at the top of the page for my efforts. That is how the site credits me for my work.
