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.

50HP95 Toshiba Plasma TV No power but blinking power light


I had the same problem with my 50HP95 Toshiba Plasma TV. It would not turn on. I read online that if you unplug a connection on my TV and it turns on, it is a bad Seine board. I could not find this Seine board anywhere online. It was either out of stock or no longer available. The TV is just 5 year old. Why would they discontinue parts for it? Then I saw a video on You Tube where someone unplugged a connection in the back of his TV to fix problem. I decided to try it. I took the back off, unplugged a connection numbered PJ63A and the TV works again. So far so good. I downloaded the Service manual for this TV to find where PJ63A was.
I also called Toshiba Tech Dept. to find out if there was a chance I can cause further damage to my TV. They had no idea.

Toshiba plasma 42hp95 tv will not turn on red led lights blinking


The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

TV will not come on.


Might not be the exact same problem as you - I simply turned the TV off one night and it never went back on. Just had the LED red light in front flashing. Was about to give up hope and kick it to the curb when I decided to try the Solution posted by CheapTech: http://www.fixya.com/support/t101749-tv_turned_itself_off_turn_back

It WORKED. Plain and simple, it worked.

How to bypass seine card? 50hpx95


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.

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.

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!!!
