TV won't turn on red light blinks and screen flashes then turns off

"My 3 year old Toshiba - Model # 49L420L was having the same issue tonight :

ISSUE : Black screen, Red light on the tv indicator, when I tried to turn it on, it would flash the Toshiba logo and then show a black screen however sound was coming out still.

Note : Unplugging the TV, modem etc did not fix it.

HERE IS THE THING THAT FIXED IT -

- I unplugged my TV

- waited 30 seconds

- after the initial 30 seconds (while it was unplugged) I held down the power button for 30 seconds

- I plugged the TV back in.

- I held down the power button again for about 15 seconds + / -

At this point the screen started to turn on by itselelf and went back to its typical green 'sleeping' screen saver and it worked just fine after!

Hope this helps everyone!"

"HERE IS THE THING THAT FIXED IT -

- Waited 1 minute

- During this 1 minute press the TV manual power button ( not from remote)

- While pressing the power button. Plugged the TV power back in and power on the outlet.

- Keep pressing the down the power button again for about 15 seconds + /

At this point the screen started to turn on by it self."
