Hello!

I have a 55VT50 that turned off and started blinking 12 times. I unplugged the speakers from the A board and turned it back on and everything worked great.

Few years go by and now the TV will randomly turn off after about an hour and will blink 12 times. I went into the service menu to check any issues but I don't know what any of it is or if it shows any issues. Here are some pics.

I'm assuming I will need to replace and fix the A board but wanted to check here first. Any help or guidance is appreciated. Thanks!...
