took on this OLED now.
Symptoms. Hit power, white light shows briefly and then 5 blink red code. TCON issue per chart on first picture.
I'm thinking I have a power board issue though, which is one of the options
Now to check pin voltages from PSU to main and PSU to tcon
Pic 2
1 tcon on 12 -- 0v (when I hit power this goes to 3.1 stays for short time and back to zero)
2 bl err -- 0.16
