hi minnie,
Thank agian, i had the diagram and i already checked the possible components like capacitors, transistor n diodes according to the diagram;
i repace two cap. try on the tv problem stil the same e994 blown. so i suspected the ht trans(t702) faulty. when i removed the ht tran n at the sametime replace e994. then i ON the tv without ht tran; all the green led lights are ON for few second off, protect light blinking, but e994 is ok.
now i want to check the ht tran, is there any way can confirm ht tran faulty? where can i buy the ht tran?
Your asistance is appreciated. thanks again.

Paid them off more than a decade ago, still working great, still earning their keep. Their scope and variac are the ones that get the most use these days though. _________________ You're over there, I'm over here. |
