Sony KD-55AG8 boot loop - help!

Sony KD-55AG8 OLED – Shows Sony Logo Then Black Screen, then Boot Loops

  • Model: Sony KD-55AG8
  • Type: OLED Android TV
  • Approximate age: 7 years old

Symptoms:

The TV powers on and displays the white Sony logo normally After the Sony logo disappears, the screen goes completely black The TV appears to continue booting and will restart and get stuck in a boot loop The front LED remains solid white

Sometimes the boot loop will pass and I can hear Android startup sounds I can hear sounds during the factory reset and firmware recovery processes There are no red flashing LED error codes

Troubleshooting Already Performed: Power reset (unplugged for several minutes). Factory reset using the physical buttons on the TV - green LED, then back to boot loop USB firmware recovery/reinstallation using the latest firmware - update bar gets to 30%, then boot loop Disconnected all external devices Confirmed the Sony logo displays correctly every time

My current suspicion is the main board - any advice would be greatly appreciated!
