60" projection tv went black

Possible there is a damage due to the power outage as there can be problems in the main power supply- SMPS- or if this seems intact as the clicking noise shows then some OUTPUT DRIVERS can be short. A good check on the main board is important as a fried board can only be replaced.

Suggest unplugging for 15-30 min to allow capacitors inside to discharge and reset and systems from the outage. Then plug in and see. It could be the power supply or a burned out bulb from the quick pulse of loss of power also.

Is your TV's indicator light ON? Did you try turning it on from the remote as well as from the TV's control panel?
If your TV's indicator light doesn't come ON, it could be that the fuse inside has blown due to the power fluctuations. If indicator is ON, your TV's internal power supply seems to be fine, you may have to take it to your technician.

Toshiba model 57H93 worked perfectly last night. Turned off and went to bed. Turned on this morning, and nothing, it won't turn on. Checked all cords and cables, pushed reset button, and still won't turn on. What could cause this to happen?

Audio Protect (7 Flash): When DC voltage is detected at the speaker or
woofer outputs, IC3604/pin128 (TV-micro) goes low and IC3604 turns off
the main power (AC relay turns OFF).
Troubleshooting Tips:

Unplug the tv press power on and plug it back in.
some of these units have a reset clearly marked on the back.
connect direct to wall as the surge protector may now have issue.

It is a great chance Jeff that your Power Supply Board (specially the FlyBack) could not hold the voltage requirement to let your TV set on. When local Power Utility supplier is shutdown for whenever reason, this kind of situation occurs. Voltage spikes, voltage outage, voltage drop and dimming are common things. You could replace the FlyBack and then check out if the TV stays on. This will cost you from $60.00 to $80.00, but it will not guarantee that it was the only component that suffer the shutdown. I really suggest you to replace the main power board (from $175.00 to $250.00 - with core exchange). It is something you can do on your own and I'll recommend you to check on the following site (my favorite to buy parts): http://www.vancebaldwin.com/ SithPitt
