Question about Toshiba 50HX70 50" Rear Projection Television

Toshiba 50HX70 - red blinks but TV will not turn on...

In the past when this has happened we have unplugged the set for an hour or so and then everything is fine. This time it does not help. The red light keeps blinking. There is no picture, no sound - nada. Do I need to call a repair man or is this an easy fix? (I am not technical by any stretch of the imagination). Thanks for any help.

Hi, you`ll need to call the tv guy then, you have a short in one of the power supplies, or possibly broken solder connections, either way the board has to come out and board repaired or parts changed, BMW Rider

I have had the same problem and after several trips to the shop I realised it was caused by humidity. The shop was air conditioned so the problem never happens there. A dehumidifier or air conditioner "solved" the problem.

Tv will not turn on

The blinking red light is telling you that the set did not start up due to an overvoltage somewhere in the set. Most likely the main power supply has a fault like a bad regulator IC or a component associated with it, or there is a fault in the sweep power supply somewhere. if you have no electronic repair experience, play it safe and call out a tech to assist you with this repair. Good Luck.
