i had just serviced a sony projection tv model KP-46S15. i had to replace 2 bad ic's they are stk392-010, i powered up the set it ran for 10 - 15minutes before smoke came from under the ic's heatsink. the bank of resistors had burnt up. trying to figure out what caused it.
the timer light flashed twice before i replaced ic's.
its the "D" board sony number is 1-665-347-11
resistors that burnted where r1623,r1625,r1627 and r1629
hope that helps

I cant understand what you're asking or what your stating. Could you please use some punctuation, and I would be happy to assist you.

I'd probably swap out the whole D board at this point. Who knows what all was cooked on it.

yea i should but having a hard time trying to find a "D" board for a 13 year old sony.
i picked up 2 stk392-040 ic's to replace the stk392-010's. i doubt sony has parts for those older sets anymore, but i patched the board again and have been testing caps near the jungle ic's. the guy who owns the set doesn't want to buy a new one.
he told me that he would pay whatever the cost to get it running

make sure you check your traces on those solder joints around the chips. Is it possible you could have bridged something on accident?

also, those resistors were probably what made it fail the first time. They get hot on this TV and change values.
