    Hi Launa Sparks-Hunter, thinking about hdmi control devices plugged into tv
    like a dvd player
    or a x-box
    or a play station
    try powering these devices down for 1 minute
    then power back on

SOURCE: Electricity went out in town, tv won't turn back on.

On this type of problem, the first thing I check is the AC line fuse on the power supply. Follow the Ac plug wire to the power supply board and where it plugs in, you will find the fuse. If: Then: It checks bad. Replace it. It goes out again. Call a Servicer. It is good. Check for the five volts that goes to the Main PCB. No five volts, change the power suppy (SMPS) Five volts is there, more than likely the Main needs replaced and SMPS. For a Samsung Servicer in your area: 1-800-SAMSUNG

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.

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!!!

Hi...

Main power supply is overheating. Try getting it dusted out first then check into getting it serviced

My toshiba tv picture turned black and now it won't work. How do I fix it?


Sounds like main digital board is faulty. There is no start voltage comes out from it to the back-light inverter board to start functioning. If you wish to get some details; check the site linked here. Pull up older posts.

Model 55ht1u


Hello!
Sorry, but I couldn't find any mention of P'n'P in this model's specifications.
Looks, like it just not equipped with that. Look at your Toshiba's remote control: if you don't see any PiP related buttons, it just not there. Definitely, has only one tuner, not for 2 tuner P'n'P broadcast. Some TVs must use external signal source for this feature, like an extra set top tuner box or DVD recorder with it's own ATSC tuner.
you may check TV's specs at: http://us.toshiba.com/tv/lcd/55ht1u/ .
good luck,
thanks,
Alex.

My Toshiba 55HT1U volume not working when playing games


I believe you have connected your computer to the tv? Please note that if you connected via VGA or DVI it is a video only signal. You will need a seperate cable for sound output . Connect the audio out jack of your computer to the headphones port of a tv using a 3.5mm to 3.5mm connector like this

TOSHIBA 55HT1U only shows 480i resolution instead of 1080p ( Cable TV) shud be at least 720p


Your set will automatically be in the correct resolution. If your set is broadcasting in 480, then that is what it is receiving. I would check your cable or satellite box to verify they are putting out the correct resolution.
