My tv just wouldn’t turn on one day. Had zero signs of life. Looking around on some forums and some other fixit sites, they suggested it could be the power board. I ordered one and replaced it. It worked for about ten minutes then the tv just shut off, dead again. Was hoping someone has a idea of what to do next. Any help would be appreciated.
I think you've exhausted the possible repair for your TV, the best resolution is to replace your TV with a new one. It's better to spend a penny to a sure and new working TV than keep on spending to try and repair the TV with no assurance of being repaired. Just giving my two cents.
