Question about Toshiba 50HPX95 50 in. Plasma HDTV

Open Question

Toshiba HPX 95 series

I have 2 Toshibas 42 and 50 the power light started flashing on both of them within a week. I Assumed it was the seine card, and read you can bypass this module. The 42 now boots up and I can get into the installer mode, but when I go to exit it will not power down. So I hold power it resets and then says "NOW BOOTING" and will not come out of boot mode. The 50 I bypassed and the red light went off and the green flashes three times which I heard was the D board, but the screen will not illuminate like the 42. Any suggestions? Need help please I have researched this one and cant find the solution aside from bringing it to "THE MAN"

Turn off set, unplug power. Remove back cover. On brown circuit board left of center, unplug connector PJ63A. Plug in power, but don't electrocute yourself! If you no longer get the continuously blinking red light, hit the power button. If it comes on, the SEINE module is bad and must be replaced.

My Toshiba tv model 32LV67U hdmi connectors are not responding. Other than that the tv works great. Can this be fixed? If so, how and how much will it cost to do so?


I googled the seine board number and it sells for $95. If the TV is fairly new I would write to Toshiba about the problem. I am a bit old school and do not expect certain equipment to fail prematurely. Even if the warranty ran out it is worth telling them how you feel. Maybe you can get a discount on the part or some other compromise on the repair if your communicate effectively with Toshiba. Good luck. ( I think I will check all my HDMI ports now before my the warranty on my TV runs out.)

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. :-)

Flashing yellow light on power button


It sounds like the seine board. I replaced several of these. Exteded warranty would be nice in this situation. Hope you have one.

Power ligh blinking no picture no sound


I had the same problem, it is usually the SEINE module. this unit is about 350 to 400 and they only come refurbished. You can bypass this module which is what I did and it worked sweet, and I have 2 hpx 95s they were both the same problem. This module is for HD off air only so if you are using that then you need a new one if you have cable or satellite save the money and remove the back of the TV and disconnect the module. Give the TV about 3-4 mins to reboot and HELLO TV.

Red light flashing. TV wont start.


Bypass the SEINE module if you know how. If you use off air HD you will have to get a new module.

TV turned itself off, won't turn back on


I had the same issue with my 42HP95 after about two and a half years. Same symptom, red flashing power light, reset doesn't work and most of all, the last day of the Ryder Cup starts in 3 hours. Any other time (with exception of SuperBowl Sunday). I frantically searched the web for like symptoms and came across someone that posted the fix was to bypass the Seine Module but I had no clue what that was! So what do you do? Tear off the back of the TV and look for something that says Seine on it... Right! After that failed and 500 screws later, I decided to look for a Service Manual online. Nothing like RTFM (Google it!). I paid my $11.99 for a download Service-Manual.Net and found what appeared to be the Seine Module (SEIN). Through a little trial and error, here is what I came up with. The pic below shows the location of the said Module in the red rectangle.

78c6772.jpg I ultimately found that if I unplugged the connector from the module (in red circle) and put it in the cable management loop (other red circle), the TV would power on and has been working ever since.

According to the post I read (grains of salt) the SEINE Module is only needed if you are using coaxial type (rabbit ear) antenna. I personally don't know but it works for me. Granted, this is my experience and may not work for you but for $12, I am a happy camper. BTW, what a Ryder Cup!!! USA USA USA!!!
