Re: Re: Power supply issue, I've got the same exact problem
Glenn Ray Posted Aug 27, 2004, in response to:Gary Gendron
I've got the exact same problem. I replaced Q601,Q602,fusible resistor, 2SC5148 power transistor & the flyback. It powers up and I get good picture for 3 minutes, then the picture goes dead. If I cycle the power, I get the picture back for a short time. Q601 & 602 are HOT. What's next?

Well, not exactly the same problem... Since I haven't replaced the flyback yet. I ordered a cheaper non-OEM part so I am not sure if it will last (then again the original didn't last, did it?!)It sounds like something in the HV circuits are still partially shorted but don't know what. I finally got a schematic (lousy copy)so I'll be probing deeper if my cheap flyback fails. Sony replaced the original flyback with a new part # but it is $150 as compared to the $23 non-OEM part.
Wait and see... good luck.
