Hi ,
I have this
Sharp TV 81FF-57E

This TV fault started with intermittent turn on and off while on standby;

then stuck on standby with orange led on .

LOPTR BUH1015HI was shorted . I tried changing this but the new part shorted immediatly as well . I can't find any other parts faulty . I checked Q603 Q604 and C604 and other caps and Ds but all ok .
there is 140V at the collector pin of the loptr ( after removing the transistor ) but only 0.2 V at the base .
Any help please is appreciated .
thank you
