Panasonic 55VT50 12 red Blinks

[Glitched]

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!

I'm not 100% sure about this but,
SOS: 0C
0C hexadecimal is 12 decimal, so I think it refers to the error code which ties in with the blink code you see on the front led.
Found this regarding blink codes but do not know if it's applicable to your model.

Panasonic TV Blink Codes for All Panasonic Models

Panasonic Plasma TVs have a built in circuit for fault diagnostics. If a fault occurs on one of the internal
circuits, the firmware in the TV will detect it and output an error in the form of a blinking LED lite.
The exact error is represented by the number of blinks in each series of blinks. By using this fault error code,
you can diagnose the problem with the TV without even opening it.
First, be sure you are counting the blinks correctly – it is very important to correctly diagnosing the problem.
To do that, turn the TV OFF, and then back on and count the number of times the LED blinks.
Repeat the process to confirm, and then look up the error code on the table below. This will very quickly diagnose
the problem and tell you what board needs to be replaced or repaired.
