My Regza is less than 2 years old and it suddenly turned itself off. I cannot turn it back on and there is a yellow led light flashing. What could possibly be the problem? Is there a fix for it?

More likely to have somting shorted out in the power supply or in the backlight inverter board. Right now the 5vdc standby power supply is working but not the rest.

Toshiba 46 inch regza yellow light blinks and picture wont come on but I have full audio


Most likely the power supply board needs to be replaced. It could also be the T-con board or less likely the display itself.

If you don't know what you're doing, DON'T OPEN THE TV UP TO FIX IT, THERE ARE HAZARDOUS VOLTAGES ON THE POWER SUPPLY BOARD, EVEN WEEKS AFTER THE TV IS UNPLUGGED!

If you don't know how to do it yourself, find some local Electronic repair shops, get quotes, try to find reviews on the shops.

What's your problem? won't turn on..... yellow/orange light continually flashes three times...


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.

Recently I purchased Toshiba REGZA 47 XL 700 E is LED. Is this TV LED ?


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

Wont turn on but yellow light is flashing


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.

See Fixya tips and tricks:-

While the model of your set is slightly different, the checks described generally still apply, as it is very similar.
