I have KV35S26, I replace Q601, Q602, R607 and Q502 severial times. I bought four sets from Electronix Online SONY POWER SUPPLY KIT (80-113 ) already.
First time: 4 weeks ago.
The TV dead, no power, After I replace Q601, Q602, R607 and Q502 ( all of them are damaged), it worked for 3 weeks. sometime it shutdown ny itself, but I can turn it on again. But one week ago, I can not turn on it anymore.
Second time:
After I replaced Q601, Q602, R607 and Q502 again, they all be damaged immediately. I saw a spark around C610. I found C610 is short. all Q601, Q602, Q502 and R607 are damaged.
Third time:
I replace Q601, Q602, R607, Q502, C610 and C609. I am sure Caps and resistors around Q601 and Q602 are right. After i turn on the power, the TV got normal for 5 seconds, then dead again.
Now i suspect that Q502 short causes Q601 and Q602 short. Do you have any suggestion ? If I need to check to flyback, could you give some detail direction. The soder joints for T501 ( HDT ) looks good to me.
Thank you very much.
