@chaturanga 6 blink error code for your Sony is an indication that it has a backlight / inverter problem. You'll have to take a look at the boards. Unplug the TV remove the back and check for obviously damaged components. Post some pictures of all your boards with your question. That way we can see what you see. Use this guide [guide|21499|commentid=417084] for that. You will need a multimeter to check a few things but ultimately it sounds like the error is coming from your inverter board
