When i turn the tv on there is a white bar on the screen

Select the input channel for your Fire TV - Turn on your TV and select the input channel for the HDMI port you used to connect your Fire TV. You should then see a loading screen with the Amazon Fire TV logo 4.

TV SCREEN TURN WHITE

Okay- the three cables (red, white, and yellow) are called RCA plug connectors. They are commonly used to carry audio and video signals.
Plug them into your Xbox according to the color codes- red cable connector to the red socket (jacks); then white to white, and yellow to yellow.
Now connect these leads to the RCA input jacks in the back of your t.v. - maintaining the same color code connections (red to red; white to white, and yellow to yellow)
The RCA input jacks on your t.v. should be labeled with an input number, to distinguish itself from the other inputs, like HDMI, S-Video, and such.
After plugging in your Xbox to the wall outlet or surge strip, turn it on.
Turn your t.v. set on.
With the remote control that came with your t.v. set, open the menu bar, scroll to... and open the "External Output" menu.
You should see a list of [however many] inputs your particular t.v has. Scroll to the input number that the 3 RCA cables are attached to, and press that number as the default video screen.
Exit the prompts and your Xbox video screen should be displayed.

What you are describing is a burn. The 4:3 aspect ratio black bars are the culprits. The best way to get rid of them is to display a white screen and let it sit over night and hopefully they will be gone.

Try to keep still images off the screen as they will burn.

The senser bar can ONLY be used if it is ON TOP of the TV OR BELOW it.

I removed the HDMI cable and connected with component video and rca audio. No more white screen.

Picture quality looks good. I don't know if it's as good as HDMI, but then I don't need to reboot the TV three times to get to teh on-demand menu... Grrrrr....

I am trying to contact Toshiba on this as well. I have seen several reports of this problem on the web.

my Panasonic CT-36SL145J won't turn on

Thin white dashes on top of screen is PERFECTLY NORMAL. It is nothing wrong with the TV, it is the broadcast. What you are seeing is the very bottom of the timecode running. It doesn't happen all of the time or all channels. It usually happens with old 4:3 commercials predating "Digital TV." This is mentioned in your Users Manual. You should be able to adjust the horizontal/vertical position in the menu settings.

look behind your vcr there switch there [test signal]on and off turn to off the black and white bar will lost.
