Could be a fault code or the TV is receiving a firmware update over the air.

Your on the right path, sounds like something gave out on the power board

Toshiba Regza 37in - 37HL17
TV will not turn on - Yellow power ind. Light blinks three times...
Fixed with a firmware update (hard to believe, but true). Search Google for a file named: 2007SEN069.zip (don't worry if the page you find it on doesn't mention the 37HL17 - it worked fine). Unzip the file, and copy the 3 folders and 3 files to the root of a small SD card. The SD card MUST be 2GB or less in size (I used a 1GB card), and it MUST be formatted with FAT-16 (not FAT-32). Mine was pre-formatted as FAT (FAT-16). The SD port is on the back of the TV behind a cover plate near the power cable. You do NOT need to remove the back cover of the TV, just the small cover plate (1 screw). UNPLUG the TV; remove the cover plate; insert the SD card (prepped as explained above); Plug in the TV; Watch the yellow lights blink, then turn blue, then go dark; UNPLUG the TV; remove the SD Card and replace the cover; Plug in the TV; Yellow lights will blink a few times (this is normal); when blinking stops, turn on the TV and you should be good to go. :-)
Pictures attached are from a Toshiba software upgrade bulletin I found online.

Yes and NO your tv is a LED. To be exact it is a LED Backlight LCD TV. An LED-backlight LCD television is an LCD TV that uses LED backlighting instead of the CCFLs used in traditional LCD televisions. It is not a true LED display but is called "LED TV" by some manufacturers.[1] The use of LED backlighting has a dramatic impact, resulting in a thinner panel, less power consumption and heat dissipation, and a brighter display with better contrast levels. You can go to http://www.regza-asia.com/pdf/LEDTV/XL700/47XL700SPEC.pdf and look at the complete specs for your tv

If the tv doesn't reset after being unplugged awhile, there's an internal problem, and the unit will have to be serviced. Make sure the cable input isn't loose, and that the cable cord is good. Aside from that, there's not much you can do. Some cities have mobile TV repairmen that will service the unit in your home, and it's much more convenient. Look in your Yellow Pages under TV Repair.
Good luck, and hope this helps.

Hi,
TV needs back light inverter board replacement as discussed in chat session, required board is available with shopjimmy.com
Thanks.

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.

Yes. The Yellow LED blinking 3 times is a normal boot-up, but if it keeps doing it -- it needs the firmware "update" (which is more like a reload because it got corrupted.) The problem is, no one talks about how to do that. (there is a PDF and firmware on toshiba's website, but it lacks some crucial details.)

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:

http://www.benjammin.net/www/pages/techtips/Toshiba-Regza-42HL167.html

Once I figured out some of the facts, it was a breeze...

Here's how I fixed mine...

Look inside the back of the TV just above the power cord - there are two small LEDs, one green and one yellow (no need to open the case - you can see them through the cooling slots). In my case, the green LED would light for a few moments after plugging the TV in, then the yellow one would light and stay lit.

Go to the Toshiba site and download the latest firmware upgrade.

Copy the firmward upgrade to a SD memory card using your PC (SDHC cards larger than 2GB don't appear to be supported by the TV, so use a smaller one). I copied *both* the zip file as downloaded from Toshiba, and the contents of the zip file. That is, I expanded the zip file and copied the contents to the SD card as well.

There's a metal cover over the SD card slot on the back of the TV. Remove it (a single screw)...at one point, Toshiba has directions on the firmware download web site.

Unplug the TV and insert the SD card. Plug in the TV again, and in my case, those little LEDs stayed green. I saw none of the instructions on the TV screen - rather I just let it sit for about 10 minutes, then I unplugged the TV, removed the SD card, and plugged the TV in again. Viola - the TV works.

I'm thinking perhaps Toshiba uses a type of memory that requires battery backup, and if the TV is unplugged for an extended period of time, it's necessary to re-flash it.
