Facing TV Problems? Ask a TV Technician.
I'm sorry, it is not possible, red power light can blink from 1 times to 14 times to present an error code 29 times is not possible so please recheck.
Just for example, light would blink 7 times, pauses for 3 seconds and again blinks 7 times...
then it must be 1 time it is blink ...blink ... blink ... it does that 29 times and stops
OK, so no change in blink pattern after power board change, is this correct?
Also, do you have multimeter and can check volts on power board to troubleshoot the issue properly?
