    The tech manual on this one says that there are a few different yellow blink codes. A fast blinking yellow light after restoring the AC power (or after power outage) is normal, and in an ideal situation should STOP blinking after a while at which point the TV is 'booted up' and should power on.

    Is this blinking light a constant 'fast blink', and if so, does it stop blinking after a few minutes of being plugged in... or is it blinking three times, stopping, then blinking 3 times again?

    If you post an exact model number I'll look it up in the database to see if there have been any other recent instances of this problem with this set. Model number will be on a tag on the back.

    Have you tried unplugging the AC power for about 10 minutes and retrying?

SOURCE: Doesn't power on - Amber LED Blinking

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.

SOURCE: TV auto shut off-power indicator light blinking-won't turn back on

You could have gotten an electrical surge that put your set into a shutdown condition and unplugging the set and letting the Microprocessor reset will fix this problem if it dosent blow out the main power regulator as you still or might I say have a regulator IC problem. IF THIS PROBLEM HAPPENS AGAIN MORE THEN A FEW TIMES WITHIN A SMALL TIME FRAME I WOULD HAVE THE SET LOOKED AT BEFORE THE REGULAOR BLOWS SOMETHING OUT!!!!

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. :-)

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.

Picture loss after picture begins to flash. blue and yellow light


Most likely the lamp is dying. Try replacing the lamp before calling a repair tech. What does the Owners manual say about the blink lights?

Blinking yellow light ,no picture or sound.


You have done all you can do. If you had a power outage, when the power came back on a it surged and probably caused a Power Supply problem or something in the micro controller to fail. Either way it 's not good. I would call Toshiba and let them guide you to a Service Facility that can check it out. Depending on your Homeowners Insurance, repairs could be coverd or unit be replaced depending on cost to repair.

Power problems problem on


I would try a power drain:  Unplug the TV's power cable so the TV is not grounded to the house.  Then press and hold in the TV's own power button for one minute to drain the capacitors. Plug the TV back in and see what happens.  If the TV will still not turn on, I would say you have a problem with the TV's mainboard as a dead power supply will not light any LED's for you.
