42hl67 has a continuous blinking yellow light in 3 blink intervals, how do I fix this?

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details of many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

Hi,

Here is a whole list for you :

Mitsubishi Blinking Codes :

Constant Green - TV is Powered On
Constant Red - Lamp Failure
Constant Yellow - DMD temp is very high
Blinking Yellow - Lamp cover is open
1 Red Blink, 6 Yellow Blinks - Color Wheel Failure
3 Red Blinks, 4 Yellow Blinks - Lamp Failure
3 Red Blinks, 6 Yellow Blinks - Exhaust Fan Not Working
3 Red Blinks, 7 Yellow Blinks - DMD Fan is not rotating
5 Red Blinks, 7 Yellow Blinks - Ballast Problem
6 Red Blinks, 6 Yellow Blinks - Lamp Missing, Bad Cable between lamp and ballast

And the Lamp cover must be here somewhere in your TV :

blinking yellow light usally means the motors are not engaged so find the levers to reengage motors

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.

The 4½ minute interval can be changed to 1½, 2½ or 3½ minutes as follows: Press and hold the Lock button until the light blinks (about 10 seconds). A single blink indicates the the time is reset to 1½ minutes. Repeat the procedure and the light will blink twice, resetting the timer to 2½ minutes. Repeat again for a 3½ minute interval, etc., up to a maximum of 4 blinks and 4½ minutes.

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.

one of the cartridges is dead and must be changed. buy new one and the problem will be solved.

How many times red light blinks when TV lost picture? There would be interval of 3 seconds in red light blinks so count pause to pause and let me know.

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:

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

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.
