Question about Toshiba 42HP95 Television
I recently bought a plasma Toshiba and it's been working great, but after watching the TV for about 4 hours continuously on the third day, the TV turned itself off, and the power light is blinking red. When I press the power button, it won't turn back on. The model number on the tv is 42hp95 incase that helps at all. Any ideas?
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.
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!!!

Wow, thank you Cheap Tech. My husband was a doubting Thomas when I showed him the picture and read to him how to fix the TV. I will add though that we first unplugged from the wall only then the white connecter. When we plugged the TV back in it still blinked. My husband got mad and said call the repair man. But I went back and read where someone unplugged the plug from the back of the TV and the outlet. Voila !!! We let it set for a few minutes and plugged in the plug on the back of the TV first then the outlet and held the TV in an upright position and the TV came right on. So please others who read this........
1. Unplug the outlet first, then the back of the TV, then the white connecter, let the TV set for at least 30 mins.
2. Plug in the back of the TV first then the outlet. Stand TV up then turn on.
You just saved us hundreds of dollars. Thank God for the internet and great people like Cheap Tech.

Cheap Tech is THE MAN!!!! Thank you so much for your assistance - especially for those great photos. I paid big money to have a tech come by to solve the problem. After lots of pointless back and forth and many dollars later, no solution. Fortunately, I was able to negotiate to get all of my money back. At any rate, I am very grateful to you for taking the time to help others with this problem. Thank you thank you thank you.

Ok here is the deal. I was about to order a new Philips from Dell. 2ms 120Hz 1080p for 850 - but still.. 850, financed. I thought I'd give this solution posted by CheapTech. I popped the cover off, and unplugged the SEIN module. My daughter was like 'that's it' ... I guess so lol. I was not optimistic. I figured I had at most a 15% chance of success, given the 6 major components plus the SEIN module. But I was pleasantly suprised that ... it worked! I recommend anyone who may be down and out to try the fix posted by CheapTech.. it worked for me!

Ok guys i have the same problem. mine just shut down and wont turn on. plus the red LED flashes. I sent mine to the shop and they told me the Y SUSTAIN BOARD PCB needs to be replace. This shop is a toshiba registered shop so im assuming they are reliable. Now the problem is toshiba doesnt make the replacement parts anymore. So the shop called me and told me they cant fix it that i have to call toshiba myself and make some sort of bargaining deal. unfortunately I didnt buy the extended warranty that suck real bad. regardless the tv is only 2 years old. As far as i know toshiba should have replacement parts for atleast 7 years and this is by law. So I guess if they have more complaint about this dilemma for sure its a recall. more complaints the better. so guys start calling!

I have the same problem. The 42HP95 is only 18 months old, with average viewing of 20 hours per week. I can't get it to turn on, just keeps blinking red.

Thank you, Cheap Tech! My husband would not believe this could work and was ready to charge up the credit card for a new TV, but I decided to undo all 40 screws (about 15 minutes) and pulling that plug actually worked! Our old Toshiba has worked fine for years, but yesterday that dreaded flashing red light started and it wouldn't come on. I tried blowing out the fans with a can of air and tried turning the set off for 24 hours, but those tricks didn't work. So I finally took the back off and pulled that plug you suggested and HOORAY! The TV now works again! Thanks, also, to everyone who commented that it worked for them, too, as you all motivated me to tackle those screws by myself, a middle-aged woman. So happy!

Thank you CheapTech for your solution to my problem of the blinking red light on my 2005 Toshiba 42HP95 plasma TV! The simple unplug of the Seine Module has corrected the problem and the TV will now turn on! Awesome!!!

I'm having this same problem... but with the 42hl196... tried looking for the extra bypass plug but can't seem to find it anywhere. If you have any ideas please help!!

I did exactly what was suggested here, and got 3 blinking green lights. Got irritated that the problem wasn't solved immediately (microwave generation >.<) started reading other forums. One suggested waiting half an hour. By the time I was done reading, I decided to hit the power and TV came on! Anyone want to help me put this monolith back on my wall?

Hey thanks! My Tv was bought in 2005 and I woke up this morning to that dreadful blinking red light. Nothing would fix it so i decided to do a search. Read your solution, took back cover off and bam! My TV is fully functional! Again thanks for everything!

TV gave out this morning and after reading your advice it's working again. Amazing. Thanks so much for posting this and adding the pictures to show exactly how it's done.

Well sounds like you might want to get rid of the TV or the cats. That said... if you have a Toshiba 42HP95 I would be willing to purchase the base. I lost mine after mounting it to a wall but recently moved and can't find the base. [email protected]

Same thing happend to me, and the local repair shop said it would be $500 for parts and labor to replace the SIENE/SIEN/SINE module...
I had listed my broken TV on CraigsList and someone was kind enough to send me a link to this article! It worked like a charm, and came just in time because I was about to sell it cheap for parts...

CheapTech - thanks for the reply post. The issue with my board was that it controlled the cable card board which we used instead of an external cable box. We still have the ticking from the power supply - am just waiting for the Samsung prices to drop a little lower and the TOSHIBA is off to the curb!

Technician just left the house for the 4th-5th time. He replaced the power supply (with remanufactured) and Y sustain board. Nothing. Replaced the power supply (this time with brand new), Y sustain and processor. Nothing. The only other possibility was the 2 remaining boards which are part of the plasma screen. The screen costs more than the TV is worth so they won't repair it. I have the service contract with Best Buy, so he hands me a receipt and tells me to return the TV to the store and exchange it for a brand new one.
Solution? Always buy the service contract on TVs. Toshiba stopped making parts for this model, but Best Buy was able to get some.
