The three blinks of the red light (that repeats) indicates a failure of the power supply board in the set, and in most cases requires replacement of this board to fix the issue.

That said, was this something that you're looking to repair yourself? Or looking to see what it would cost at a shop?

Myself it I could do it.....
TV Technician: Aric, Technician replied 6 months ago

Okay, I need to know if that light starts blinking soon as the set is plugged in- or after you press the power button?

Soon as I plug it in....
TV Technician: Aric, Technician replied 6 months ago

Okay, unfortunately this means the issue could be the power supply OR the mainboard. The layman's approach is to purchase both boards and replace one at a time to see which allows the set to power up- and send back the offending board (the power supply and mainboard work in tandem to allow the set to power up). I'm pulling these boards up now.

Actually that model number is ***** right. What's the model number off of the sticker on the outside back of the TV please?

The power supply (most likely culprit) and mainboard are both at the link below for purchase, but are showing as currently out of stock:

http://www.shopjimmy.com/toshiba/55tl515u

You can try using the part numbers shown on that page to scour used sites like eBay, or TV Parts Guy to see if they become available, but otherwise it appears these are hard to track boards.

Alternatively, if you're not comfortable with this type of work, then at a shop this is $275-$350 parts and labor, which is typically not cost effective as a brand new 46" LED Smart TV starts at around the same cost. However if you'd like to inquire on repairs, or seek a 2nd opinion, you can use the link below to locate a shop in your area if you'd like:

Other than that, I'm sorry for the bad news and wish there were a quick fix.
