Re: Sony Bravia KDL-46EX723 - 4 blink code



I have the same exact problem. Or at least I did until I bumped a pin with my multimeter. I was just going to replace the LD board and/or the BATV board based of of what I saw online.

I assume we check pin 7 (BL_ERR) to pin 1 (GND) correct? When looking at the BATV board and CN6002 is in the top left corner. What is the pin layout. Is 1 at the top or bottom?

I was getting about 3.61V one way and 0.00V the other way.

I understand what most of the boards are BATV, T-CON, LD, G4B...
