Blinking power light toshiba tv

These 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.
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

TV turns itself off, then on automaticlly

The fan should run for a few minutes after shut off to cool the lamp down.

If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

Hi Daniel,

Please check if you can access the "error code operational check" to narrow down where the fault came from.
How to enter to error code operational check.
Note : The TV must be in shutdown and not have been switched off. When the TV is switched off, the error code automatically resets to 12 (no error).
Press the buttons on the front panel "Input/Device" and "Menu" at the same time and hold it for 5 sec, activate the error code mode. The LED light will flashes denoting a two digit error code.
Example : if the error code is 22, the led will flash two times pause and then flash two times and will repeat the error code for five times.

If you can't access the error code operational check , please let me know the exact pattern of the flashes of the led light and its color. Check if it will continually flashes green to give you the caused of the symptoms and best solution.

Good luck and take care.

Green led indicator light is off on my 62" toshiba

when you turn it off your light blinks because your internal fans are still spinning allowing the inside of the chassis to cool off, hence the reason you dont watch a DLP TV and then unplug it. DLP's are JUNK
