We have a toshiba projection tv model #57hx93, we lost power to house, when power came back on the tv will not power up, have checked breaker and reset still will not turn on, any ideas?

SOURCE: 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.

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!!!

I would have an electrician check to see if you have a grounding issue. Especially at the outlet that you have the power strip supply plugged in, Check to see what kind of your circuit panel is going to trip for electrical arc or electrical short. Newer panels should have both. Older just for electrical short. Have your electrician make sure your wiring is entirely copper, if it isn't and it's aluminum. Have him make sure the outlets are aluminum rated, and not designed for copper. Defintely check grounding. Good Luck

If the circuit breaker was tripped, more likely the fuse inside the TV power supply might also be blown. If that is the case there might be a short circuit in the power supply components, more likely on a diode or transistor/mosfet.
Contact these website to see if they have the parts for your plasma.
Good Luck.

SOURCE: Won't power on...

The TV probably has an internal short, most likely in the power supply. If you open it, you will probably find the main fuse is blown (which is why it didn't trip the breaker again. Don't bother replacing the fuse until you find and fix the short - you'll just blow the new fuse and probably trip the breaker again.

SOURCE: there is no power going

delicate circuits have been damaged before the fuse could blow it will need to be repaired by a service pro
