Hi @meowmix7878 ,

Try a power reset and check if this resolves the problem.

Disconnect the power from the TV.

Press and hold the TV's Power On button for 30 seconds and then release. (the button on the TV not the remote control).

(If your model has a Power ON switch and not a push button, just switch it on for the 30 seconds and then switch it off)

Reconnect the power to the TV and switch it on to see what happens.

What is the model number of the TV?

@meowmix7878 describe this “Toshiba comes on the screen then it shuts off “ in a bit more detail. We need to know if your TV turns off or if the display just turns off. You do want to remove the back from your TV and check the wiring. Possibly something came loose when you moved, but it is also possible that this is a power board issue. We would need more information and actually see what it does. Post some pictures with your question 在已经存在的问题里加入图片 for that.

Remember that Toshiba is another one of those Silent Black Helicopter companies that absolutely refuses to support our right to repair and it will be difficult to get information about any repair. Hence more reason for pictures and good descriptions.

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!
