Hello there,
I have followed your thread with great interest.
I having the same problem with my Sharp 40" TV.
The TV runs for a few minutes, then turn off,the triangle blinks 2 slow and 1 fast.
I measured this device PC7703 with my Fluke and with reference to the other optocoupler and I didn't find any differences.
Did you have to replace also the PC7703 or adding the 68k resister solved the problem.
(By the way R7029 measured ok, 81.8k)
Please advise
Regards
Nataf
