Just been given a lg 50pq3000 plasma with a typical plasma fault where the tv just continuously clicks I have checked the boards for any obvious faults but failed to find any when I plug the tv in the red light comes on for a second then just keeps clicking are there any known faults with this set? No light from the screen etc

I've unplugged the ysus and still the same and the same with zsus and the same again with the main board so this has pointed to the power supply board i will get pictures and voltages and post them later

Check diode D352 on the power supply board it may be short circuit.
