Re: TV will not power up
Check for a reset button in the back. If a reset button is not present. Unplug the unit and take the back off. Look for a blown fuse on the motherboard. If the fuse is blown, replace it with a fuse with the EXACT same rating. Hopefully, the set will come back to life. If not and it blows again, it will need servicing as there may have been damage done to the power supply. You may be able to make a claim with your insurance company or the power company to get it fixed if the power surge was caused by the power company.

Always check your plug first to see if it came unplugged from the wall. If plugged into a surge suppressor or other device between wall and TV power cord unplug from device and plug directly into the wall. If still no power make sure wall receptacle has power by using a tester or if none available plugging in a lamp. If no power at wall check for power switch on the wall. You should never plug a TV into a receptacle that works off a wall switch.
If you determine TV is plugged into a working power source and still no sign of life then the power module may be the culprit. You didn't say which model but most have a separate replaceable power module. It is not recommended to replace yourself, however, because you risk injury from shock. If you want to try it yourself get an inexpensive line tester to check the internal circuits. You will need schematics because it is unlikely modules are labeled.
If you find a bad module you can check with a company called ModusLink PTS, Inc. TV Board Repair and Replacement to repair it since you cannot replace most parts these days.
Some will say a surge protector will save electronics. I can tell you they may not help at all. A power surge is extremely fast and can over ride the surge protector. If you think you can repair this TV, I would certainly remove the back cover and inspect. Occasionally the only problem for repair is to replace the main fuse. Remember, this happens rarely. Most cases after a surge the TV will need to be inspected by a TV tech. Almost anything, in a power surge will damage the TV. There is no certain area that will not be damaged, expect it any where. Thanks for asking and show all hands of support!
Was the TV plugged in to a surge protector? It may be fried if there was a surge in power, sometimes there may be a fuse you can replace in the tv, other times the TV itself may be a goner, best to check with the company that manufactured it or the store where you bought it
I hate to tell you that this happened to me last week and mine is 18 months old. after calling toshiba and going through all troubleshooting, nothing worked. they referred me to a service center near me and the repair is $466!!!!! I have lots of power outages so they can seriously damage a tv (the motherboard to be specific). Mine is the 42 inch 535U. get a surge protector for your cable and ask your electric company to install a power shield on the meter or a surge arrester.. good luck.
Surge protectors aren't perfect... If the surge was big enough and long enough then it can cause problems. Most manufacturers have on-board protection as well. That's not perfect either. Often the surge does nothing more than confuse the microprocessor (computer) that controls all aspects of your television. The fact that the red light is blinking means that your set is trying to protect itself. This can happen for one of two reasons. Something in the set has failed. Usually the power supply inside the set possibly also a trouble in the scan section of your set. These are normally a shop repair. The other thing is when the microprocessor is confused it will do nothing further until it's reset. To reset the processor simply unplug the set from the wall and wait 10 minutes. Plug it back in and if it works then happy viewing. If it doesn't then you will need a repair.
If is a failure caused by a failure in the grid that delivers power to your set then you are usually able to file a claim for the repairs. Contact your local power company. explain what happened. If it's their fault then usually they will pay for a repair. I know the PG&E does.
There may be some fuses internal to the TV. You must be confident about you eletronic abilities. A tech can tell you more. Household insurance or your local power company can aid you in the cost of repar and/ or replacement.
That is why you are seeing more power protection. These units require more protection than a computer. After all they cstt morel
contact the power company to see what they will do for you they are responsible for power damage also the surge protection should have replacement warranty. may just be blow caps but take to a service center to have it looked at better yet have a service person come to your home to look into it.
