First thing that needs to be checked is the convergence IC's. Those IC's are located in the signal board and are really hard to remove. You need an experience technician to fix it for you :)

Toshiba theatre wide HD TV model #51H84 will not turn on. Red light just blinks slowly. Help please


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

You need a new HV transformer. Usually you can just buy the transformer itself. It's a little black tower on the backside of the tv. If it's not that, it's the convergence ic's. There's two of them, given it's a toshiba, the part number is more than likely stk392-110.
