Sony bravia TV KDL46EX720 Red LED blinks 4 times, what is this error code?
Error code is a failure on the LD board can cause TV to shutdown as a safety feature or / also main logic board, the boards costs about $50-100 at Shopjimmy, Amazon, Ebay, Rivervalley electronics. Note refurbished boards you receive at times can be bad so it's important to order from someone that offers warranty. The average cost to repair from a TV tech is about $200-$300. good luck model manuals check here- http://truemanuals.com/sony/index.php
