When tv is unpluged and pluged back in it wont power on and no lights blinck

Unplug the tv from all devices and unplug from the wall power source. After about 15 minutes, plug ONLY the power cord back in and see if it turns on. If not, than you will need to do a factory reset. With the tv pluged into ONLY the wall outlet ( no cable, DVD or internet connection) Hold the UP arrow on the remote than press and release the POWER button on the tv. This will reset everything and the blinking red light should stop. At this point you should be able to turn the TV on and off.

I unpluged mine and the light was still blinking when it was unpluged. I thought that was weird. So I pluged it back in and just heald the power button in untill the light went out. It went out within ten seconds. I pushed the power button again and the tv went on. WOOHOO!!! Just needed reset, I guess.

can you see image even the word hello keeps blinking?

Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV.
The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.

If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

If the issue continues to occur, service may be required.

Thanks for using Fixya.

Unplug for a minute, when pluged back in light should blink for a few then go out, should be able to power on after that!

power in the tv has nothing related with the DVD. The tv has to have raster (white screen) even without signal (cable, DVD, others) if the tv alone is just having the led flashing and neither sound nor video (black screen) The tv has a short circuit in some of the boards that are part of the tv system. the blinking is part of a protection when the tv was created in the factory. Refer to the technician to repair this problem.

I have a toshiba tv and it will not turn on. There is a flashing green light that comes on, but there is no picture or sound.

hold the menu bottun for 10 seconds
after press power

see if that works
