I have a Toshiba TP50H50 rear projection TV. The power light blinks, but the set will not turn on. I have tried resetting by unpluging the set, but that didn't help. How can the problem be identified and repaired?

Projection TV`s have integrated protection circuits
built into the circuit design, these circuits turn the
power off automatically when a fault has bin detected this
is in order to prevent a more costly repair, these circuits monitor
power supply , vertical and horizontal deflection
over voltage, or x ray, and also faults with convergance cercuits.
Diagnosing these faults require test equipment and a good knowledge of electronic repair techniques, and also a repair manual.

When you turn it on it might go on then turn off or it might not go on at all the power light blinks won't shut off unless you unplug the TV.j


The blinking LED is the Fault code for your set. Its shutting itself down into protection mode to stop from further damaging itself. Kinda like a fail safety. My fix instruction differ for rear projection than that of PDP or LCD but its the same. Just a dif set up inside the set.

My toshiba TP50H15 color tv comes on then off and the light blink


The flashing power light on those Toshibas is usually caused by capacitors on the power board having failed solder connections. I have fixed them before by removing the power board and resoldering the capacitors. If you have experience with soldering and electronics it is an easy repair. Most shops will recommend replacing the entire board since their labor to repair it would probably cost more. Toshiba put out a service bulletin on this issue which a good technician should be aware of. (If memory serves the capacitors are C109 and C110.  Since your TV still turns on you probably haven't blown fuse F860 which often blows when these capacitors act up.)
If you would like further help with this please post a comment back here.

Toshiba 50H50: No picture or sound, red light blinks


On alot of these Toshiba TV sets, there is a fuse called F860 that will blow and the light will flash because of bad solder connections on C 810, and C 809, on the negitave terminal. I have seen many of these boards condemed by non-authorized Toshiba repair shops. Good Luck
