I do have a Projection that has some hissing sound and I suspected it was either coming fbt or flyback transformer or the High Voltage Splitter. After turning on for 10 secs , it popped and it began to have no power. I dont no where to start specifically on testing but i have already check for any blown cap which I have seen one a 22uf ecap. Still trying to see any shorted trans. Just wondering if a 2sc5778 as well , does it really have a Voltage drop between emitter and base both neg and poss (rev position), i dont have a transistor tester so im using diode mode instead.
On the convergence board bound to the stk ic, 4.7ohms 1% tolerance seems to be on 4.5 ohms right now. Which is far from 4.65 ohms on tolerance rating. Just wondering if its needed to be changed. There is a crack as well on the HV Splitter. Its bound on the gutter for the lead going to the flyback. The gutters for the leads going to the crts seems fine.
