Question about Toshiba REGZA 42WLG66 42 in. HD-Ready LCD Television
Not my solution but a copy from another problem. Rate me =]
"The problem is with the signal board. Basically, it is not allowing the power signal to go from the on button from the set or the remote to the TV. I am having the exact same problem with my 42" LCD Regza. Currently, if you are under warranty, Toshiba does not have these in stock. They will not have them available to send until early January. My TV has been at the repair shop since December 4th. I am very upset as I won't be able to watch the bowl games in HD. If your set is still under warranty then call Toshiba help line at 800-575-5469. You will need the model number of yout TV that is listed on the front of the owner's manual. They are:
The first number will be the giveaway as to which model you have. It is the size of your set. They will ask you to try a hard reset. (Hold pwer button down for 5 seconds until you see the yellow light go solid and go off.) This will most likely not work. If it does, you are lucky. I found that if you unplug the TV for an extened period of time, ie overnight, ity may come back on. It will eventually give out completely though. Better to get the problem addressed with the manufacturer. If you are not under warranty then I do not know what to tell you. Right now I am searching the internet to see if I can find this part to maybe purchase myself. Only if it is not too costly. If I find anything I will post here for all. If you have any questions, feel free to email me a email@example.com and I might be able to give you more details on your problem. Good Luck.

Down load this firmware file p/n 2007SEN069 from this address http://www.tacp.toshiba.com/customersupport/model_firmware.asp?model=26hl67. The instructions are here also. Un zip to a blank sd card. I'm not sure if the set will boot to the card or not.
I finally got the tv to boot by constantly plugging in the a/c power and unplugging the power until it filally booted and was able to turn the set on.
Remove the sd slot cover from the lower right rear of the set, and insert the sd card with the unzipped firmware. Monitor the screen and follow instructions. Do not remove the card until the set powers off.
This fixed mine, hope others benefit from this repair.

I followed the steps at the following link and it worked for me. I have a 2007 Toshiba Regza 42HL67, but the firmware applies to many models as documented in the readme file at the location found via the link below. I used a 1gb SD card formatted FAT16, copied the unzipped files and folder to the card (wasn't sure if it required the top level folder or only the files under the top level folder so I copied both to the root of the SD card), unplugged the TV, inserted the card, plugged in the TV, waited 2.5 minutes, unplugged the TV, removed the card, plugged in the TV, yellow light flashed 3 times and went out. I turned on the TV and it has worked normally since last night.
