Hey iFitIt Community, Recently had my Sony Bravia KD-55A1 tv stop working. Any ideas on what might resolve this? (or How can I troubleshoot the electronics? To check which board is failing ) PROBLEM: While I was watching Disney+ the whole TV frozen and was totally unresponsive. After unplugging it and replugging it in it still was unresponsive - just leaving us with a black screen and no sound. WHAT WORKED: (to get the TV with green light at bottom, but still black) Unplugged tv from power. Then holding the “On” and “Volume -” buttons together (on the TV itself) while plugging it back into power. All we get is a green light at the bottom, which is apparently supposed to mean that Android is resetting. TROUBLESHOOTING: I’ve tried the following things to get the TV to work but none has: Holding power on remote for 30secReplacing power cableRemoving all connect devices (including hdmi)Going into self diagnostic on remote (Using buttons Display, 5,vol -, power on)Leaving it unplugged for several hoursHolding power button on tv, then plugging back includingTried shining a flash light at tv (not sure if it works with OLED)Turning the volume up all the way (in case its just the picture) Unsure what to troubleshoot next. Any advice?
Back light has gone. Probably needs a new board as something has Probably blown. Google the make and model and ‘back light circuit board’ and see if there is a replacement part for it. Good luck.
