回答“Blinking red light 5 times Sony Bravia 55" tv”SOLVED I had the same problem of 5 blinking lights and when powered on it showed a white screen. When I opened the back to check. It was very very dusty. So I vacuumed the PCB and all other connectors. Some places were still very dusty so took a soft toothbrush and cleaned the PCB near the tcon and other chips. I believe my problem would have been dust particles causing some kind of conduction at high humidity and causing cross talk short circuit between the connectors. I live in Mumbai and it happened during rainy season. Today is day 5 and no issues. TV is working perfectly.
