Resolved Question:

My Sony bravia turns on and then immediately shuts off. The standby button starts blinking red 13 times before it do I fix this so the tv turns on? I've already tried unplugging the power cord but that didn't work.

Thanks for the question. My name is Dan.

- What's the full model number? This would be on the back panel.

Kindest regards,

Ok, thanks. The 13 blinks you're seeing is indicative of a balancer board (aka inverter) malfunction. The inverter is the circuit that supplies power to the CCFLs in the screen... but there's a chance it could be the CCFLs themselves, too. It's tough to tell for sure which is at fault without electrical testing or replacing the balancer. If you want to replace it yourself, you'd be looking at about $120 for the part... ordering number would be 1-789-838-11 ( If you want to take that route, let me know... I can send you some replacement instructions. Else, you might consider contacting a technician. You'd be looking at $50-$75 for some diagnostics... but that would be put toward the final bill should you decide to have it repaired. Total bill should run $250-$350, unless it's the panel... then repair wouldn't be cost effective.
