Blinking of power light is fault indication. From the number of blink that occur at one time switch ON, you can get an idea about the faulty circuit side. These are called blinking codes. To know more about these blinking coded, visit the site. It has details about blinking codes to many brand TVs. Pull up older posts. If you check the site in Timeslide option, which can be selected from the dropdown list at the top left side of the display window, it will make search easy.

SOURCE: Power LED blinks red

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

If the front power light is blinking three times then your TV has a problem with the convergence. You can get the correct replacement parts and full step by step photo instructions from www.TvRepairKits.com

SOURCE: My tv will not come on. The power light blinks 3

YES, IT is short protection and 98% chance one of the resistors that protect the convergence circuit is bad.

Good news here:Set is fixable and total parts cost will be under 25 dollars (seller I know on Ebay).

If you want to confirm this: with set unplugged, remove back cover and locate the two heat sinks with fins that have two of the STK-392-110 convergence chips---look at all the light blue resistors in front of them---I bet you find one white in the middle--gone.

Set detects no voltage and a short and shuts down--3 blinks code.

I have start to finish, step by step instructions for this repair that tell everything you will need and how to do the repair--the instructions are based on my own experience doing this repair in these sets hundreds of times.

If photos and info here help and you want the step by step (I can not give my email here.....)rate this solution as very helpful as I am doing this here for free.

cd48042.jpg Chips look like this but metal in your set will be silver.

protect resistors in front will be light blue in color and most will be marked 2.2 which means 2.2 ohms is value.

Why won't it turn on?


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.

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.

Heard a pop , bulb blew out , replaced bulb , it worked for two days , now red light blinks three times pauses then three times and so on , tv won't turn off light won't turn off unless I unplug...


3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

I have a toshiba 42HL167. Love it but recently when the power is off iget a repeating blinking yellow light. Blinks 3 times pauses blinks 3 time pauses blinks either 2 or 3 times then stops for 25 seconds...


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...

Sharp lc-22sv6u won,t power on. no green light.


Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.

My toshiba 42HL167 won't turn on


Try this fix from the toshiba website. Q. I have no picture or sound, but I have a blinking power light?
Models: LCD-2007
REF:FAQLCD00090
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.
