Question about Toshiba REGZA 42WLG66 42 in. HD-Ready LCD Television
The yellow LED light blinks three times repeatedly; have tried all suggestions in the troubleshooting section of the manual
I found it!!
In my case, the 42HL167, the CPU pcb (most commonly referred to the SEINE PCB) is having issues booting and just isn't starting up.
My friend gave me his 42HL167 after this problem started after a power event during a storm and I managed to fix it by reloading the firmware.
I posted instructions on my website at:
Once I figured out some of the facts, it was a breeze...
I agree -- it seems like a design flaw. What cracks me up is that the places I called for a replacement SEINE PCB require the core (the bad PCB). Well GEE, why is that!?!? EASY FIX MAYBE?
It was. Too easy. Shamefully easy.

I had the exact same problem with my toshiba 42HL67. I bought SIEN board from ebay (the board with hdmi input connectors on it) and replaced it. It solved the problem.

Hey Im have the same exact problem with my regza 42hl67. I've had this happen to me in the past and i found that if i plug the the tv directly into an outlet, instead of a surge protector it would power on. But now that isnt working anymore. Is there any manual way to reset it other than just leaving it unplug.

hello the red blinking lights is a service code when this happens it means theres a power problem or a fualty circut. it happens alot with these new plasma and lcd tv's its very common since these units have built in protection and power loss a fualt or short will cuase this.
the tv needs service the tech will know what to look for according to the number of blinks.
hope this helps.

Try this fix from the toshiba website. Q. I have no picture or sound, but I have a blinking power light?
1. Try resetting the TV by disconnecting the power for 30 seconds and then plugging it back in. If this has no
effect, try moving the TV to a different power outlet that has been tested and is known to be good.
2. If your unit continues to fail, please contact our Customer Solutions Department at 1-800-631-3811 Monday
through Friday, from 8 a.m. until 7 pm CST for a local Toshiba Authorize Service Station Hope this helps you with your problem.

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.

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.
