Yet another clicking PSU (BN44-00162a)caused by failure of QX801 and QX802. Replaced all failed components including SMDs. TV now comes on fine but QX801 and QX802 (FQPF11N50CF)running very hot at over 100c after 30mins running TV tripped off. After a few minutes I switched it on and works fine again. Does anybody know what temp QX801 and 802 normally work at? Also any idea if this is the normal working temperature why the power supply would have tripped off without causing any damage?
