Chosen Solution
Hi all, While watching the TV, it will power off and the power LED will blink 10 times. Then we unplug the TV for a while, plug it back in and it works….for a while. It does seem to happen more frequently in warm weather but the correlation isn’t perfect. Have replaced PA and H boards and cleaned out all the fans but this has not solved the problem. Suggestions? Thanks, Charlie
@charlieopp this is one of those case where I’d be looking a the power (P) board more closely. Your new boards are of course new boards etc. Check the caps and traces for obvious damage. It is easily possibly that weak capacitors fail easier in higher temperature. Of course can’t rule out other components like MOSFET’s that have the seame behavior. You can always post pictures of your boards with your question. Use this guide https://www.ifixit.com/Guide/Adding+imag… that.
