please switch outlets and attempt to turn the tv on. If this does not work, please schedule an in-home diagnosis from a company like Home Depot or Geeksquad. They might use a multimeter to check current flow through some of the tv circuits to determine whether the power outage damaged any of them.

My flat screen tv cuts off and on while the power but is on what should i try before i buy a new one .... I have a ...
Feb 3, 2011 - TV/VCR/Stereo Troubleshooting/Toshiba TV power outage - no power... we had a power outage (they're calling rolling blackouts due to power grid ... but I admit I'm now afraid to turn it off for fear it won't come back on again.
May 27, 2015 - My toshiba tv is flashing but won't turn on with remote or power botton on tv itself ... dang this worked for me but after a minute it stoped working.
pull out the plug or just turn it too off for 20 minutes and plug it back in/turn it on. when power goes off the compressor will click and keep trying to restart. this also happens with AC s turn off and let sit usually fixes most of these
Pull the plug and with the power disconnected hold the power button on for 60 seconds. After at least the 60 seconds plug the tv in and try to start it. If it works great if not , hold the power button in the on position for a count of 20 with the tv plugged in . If theres still no Joy try power with one of your volume buttons at the same time . One of these should provide a hard reset for the tv.
Tries unplug,replug an hour later,let the tv reset itself back to factory setting.After,turn on the tv,go to the menu,go to sound on ur menu go down to reset the sound.The functions should go back to normal,not than.Ur tv Tuner signal board have a short,in the power outage occurance.
This TV might have been affected by the power outage even if it was not ON at that moment. There is a standby voltage still present even when OFF and connected to the AC line.
There might be different failures on this TV:
1. The power supply might be defective after the power outage.
2. The main board could also be defective since the power supplies for today's TVs are not well regulated and once the voltage getting to the power supply increases, the standby voltage voltage will also increase damaging voltage sensitive components like the microprocessor or memory circuitry.
