You are probably experiencing primary stages of a convergence IC failure. This repair is composed of replacing two output IC's and alignment. Standard repair is around $350

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.

I heard a pop on the Toshiba rear projection TV (model #62hmx84) and immediately lost the picture


Sir the problem of your unit is the lamp try to replace it it is much better to use a gloves and wash your hand after replacing the lamp because this lamp contains mercury. follow this steps.
1. Unplug the unit to main ac outlet. Remove the bulb housing cover from the back of the TV. Using a screwdriver, carefully remove the cover to reveal the old bulb. Using a cloth, remove the bulb from the TV by first unplugging it from the wiring harness. Carefully rock the harness back and forth until it comes free from the bulb. Push in the bulb slightly and turn it a quarter-turn to remove it from the bulb housing.
2. Install the new bulb. Do not touch the new bulb with your fingers, as any grease or fingerprint from your hands will damage the tiny mirrors in the bulb. Instead, carefully handle the bulb using the cloth. Insert it into the bulb housing and secure the door. Test the unit. Plug in and turn on your Toshiba TV and make sure that the new bulb is installed properly and that the image looks crisp.

3.
Reset the lamp time counter. Each Toshiba TV comes with a lamp hour meter stored in its software. If you do not reset the lamp timer, the unit may stop operating when it gets to a certain time (refer to your manual because each Toshiba TV is slightly different). To reset your Toshiba lamp timer, turn off the TV, wait 10 seconds, hold down the "on," "menu" and "input" buttons on the remote at the same time, and turn the power back on. A yellow light should appear in the bottom corner of the TV indicating that the lamp timer has been reset.
Hope this help good day and best regards.

Unplugged my 32LV67U to vacuum behind it and now it will not power up. Yellow LED keeps blinking and I waited several minutes but tv will not power up. Worked perfectly until I unplugged it. Called...


That wall outlet may have frequent surges so try another wall outlet see if it turns back on. If it turns on be sure to use a surge suppressor and never plug the TV directly into the wall outlet. The AC surges will kill the power supply of the TV in short time. See if there's a kill-switch near the ac adapter of the TV if there is turn it on.Get a surge protector/suppressor then try plugging it back in the wall. If still no power then the power board is already damaged, you can send the board too me and I'll repair it for you or seek your local repair center.

Toshiba 50hp95 will not respond and has flashing red power light. It seems many people have this problem, what's the solution? We have tried all the Toshiba suggestions.


My 50hp95 had the same problem; the red power light is flashing and the tv will not turn on. I unplug the power and plug it back in and the TV clicks, but the power light continues to flash red. My problem was a bad Seine module which you can bypass if you do not need to watch HD off air programming. Since I get my HD from the cable, I can bypass it. All you need to do is remove the back panel from the TV (unplug the TV first) and on the main circuit board unplug the white connector labeled PJ63A. The main circuit board is the one in the center of the TV and the PJ63A connector is the bottom white connector on the left side of the main circuit board (the label is printed in white on the circuit board under the connector). Once I plugged the TV back in it worked immediately.

Tv won't stay on


i have seen this before and it may be the front power button being stuck and when your remote turns it on the stuck button turns it back off again. I have an older mitsubishi that will not boot up right sometimes and i have to unplug it and plug it back in fot it to come on. I used to pick up broken tv and fix the power buton and resell them
