Question about Televison & Video

I recently purchased a 32''flat screen TV. There is a small white band that runs across the screen. Then starts all over again. Do you know what might cause that? I still get a picture but can see the band in the background.

    I'm not sure what the power point is and where it is located.

    i asked about the white band running across my screen continually and you suggested turning off the power point waiting 40 mins. and then turning it back on. this didn't solve the problem. any other suggestions?

Hi,

If I may offer an alternative possibility.... it could be interference/noise. If the white band appears in cable/TV mode then, possibly a noisy cable line. In some cases it would appear only on certain channels. If it appears on any other source other than TV/Cable such as your DVD or VCR, then it could be electrical. Possible sources of noise/interference are:

  • electrical from any of the other powered devices. Try plugging the flatscreen in another outlet. You could also try physically relocating either the flatscreen of these devices. These may include electronic ballasts of lamps, electronic dimmers, SMPS (switch mode power supply of any electronic devices including your DVD, VCR, try powering them off & unplugging them;
  • RF noises such as from the DVD, VCRs, Game Boxes, wireless telephones, wireless intercoms;
  • it is also possible to have RF/electrical intereference to be generated by neon lights, special aquarium lights or externally piggy riding in your incoming cable line.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

I hope you see these bands on cable view and you wont see them while watching dvd player.
Its noise of lose connection of antenna pin,
Please check antenna pin and cable. Perform auto tuning/ auto search in tv to minimize the noise factor.

If you just bought it then don't try to fix anything inside the tv as it is a hardware problem and doing so would void the warranty. Take it back and get a different one or have the place you bought it from get it fixed since it should still be under warranty if you just bought it.

let me know if you need anything else

It was hardware failure, there must be a defective on the parts inside the TV, and this is now not functioning as normal.. As you mentioned that it was recently bought and i just advise you to put the unit into warranty..

You're verical output IC is dead, this might because of a leaky capacitor on that section which causes the lines across the screen.
The processor shuts down the unit automatically to avoid further damage to your tube.

Send it to repair shop to isolate the problem. This is fixable.

My 50" Plasma has developed a band across the middle of the TV


All I can say is when you watch T.V. the plasmas run off of plasma gas and when you leave something on for so long it burns in the screen. I have the same T.V. and when watching like the weather channel it leaves lines but they go away. If yours are permanent then you can't do anything, but it may help if you go on your remote and go to "menu" then look for "setup" and scroll down with the arrows on your remote. Look for "screen burn protection" and select "white screen". This will make your whole screen white and it may take out the lines. If you let it sit white it won't hurt it. All one color won't hurt, the only thing that hurts is like bright white lines in front of a dark background. Just give your T.V. a break from time to time ESPECIALLY ON VIDEO GAMES. T.V. shows that are HD usually have their channel icons that move or are very dim and they won't hurt. Just go to what I told you and let it sit about 20 minutes, if that doesn't help, then the T.V. you have i believe comes with a 2-year standard warranty and if it's under warranty take it back if you have the reciept. If you don't have the reciept then call 1-800-SAMSUNG.

Hi, tubes getting tired, band-aid fix you can do is remove back of set and turn up(clockwise) the screen control( small black plastic control mounted on side of flyback transformer, do not turn the knob marked focus) until you see a whole bunch of white lines across the screen, then turn same control counter-clockwise until all the lines go away, try several different channels to be sure all the retrace lines are gone, you`ll get up to 1 year more use out of it, than she`s done, good luck, BMW Rider
