Facing TV Problems? Ask a TV Technician.
Hello. My name is***** can assist you with your question.
The first thing I'll do, is upload the service manual for you. This will provide a much more in-depth view of the troubleshooting procedures for the TV that you could get otherwise. Here is the link to that:
I honestly don't know what you mean by that. The only reason you would possibly need firmware is if the original part was replaced with a different version of that part. And even if that's the case, getting that firmware is impossible or nearly impossible. You would need special equipment to flash it. The way to diagnose this would be electrically.There's a very good chance that the logic board was not the only part that failed.
Is there a pattern to the blinking? Like x number of fast blinks, pause, slow blink, then repeat?
