This may be some kind of local interference form a close by device. Check around the set to locate anything that may be causing some sort of interference with this LCD set. I would also reset all control settings to the default setting and if the problem persist, you may have a main logic board issue.

Hi and welcome to FixYa,

May I offer an alternative suspect?

To my understanding a Protron PLTV-32 is an LCD HD Ready TV unit. A common problem with this particular model is the power supply adapter. Insufficient power delivery can be manifested in many ways including one as you have just described.

Adapter specs:

  • Proton PLTV-32 LCD TV
  • power supply M/N LU32A1A3
  • Input: 100-240V 50-60Hz 3.0A Max.
  • Output: +24v-6A---12V-3A.
  • Ac adapter connector to the flat Tv screen needs: 4 Pin Din Plug.
Pls check likewise if the blower/fan in the adapter is working. It may be a heat related issue. Alternately, it can be a capacitor in the primary side of the power supply.

Proposed course of action would be to use a voltmeter (DVM/VOM) to check for the presence/absence of correct voltage at the 4 pin plug. It may be necessary to open the power supply for an ocular inspection. Capacitor would have physical faults when defective; blister, splits, oil leak, bits of brown paper, bulging to or bottom.

If you are considering a DIY (do-it-yourself), this would require familiarity with electronic circuitry and components, use of a DVM and a soldering iron as well as safe practices when working with electricity. It may also be to your advantage access to a Service Manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable with a DIY, perhaps your best bet would be to seek the services of a qualified professional.

Good luck and thank you for using FixYa.

    There are two types, a wand or coil type.
    Both work the same way.
    A bit of advise first though, if you wear a watch take it off before using the coil as they emit high levels of magnetism and could damage your watch.

    TURN THE TV OFF!!!!! and unplug it.
    Plug in the degauss coil.
    Put the coil to the centre of the TV screen.
    Press the red button on the coil (or any other activation device)
    The coil will start to hum, slowly move the coil in a circular motion whilst moving the coil slowly away stepping back from the tv.
    I think at a distance of approx 4 feet you can turn it off.

You can try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..


Good luck...

It can be the sustain board or the buffer, is this a plasma model;?

    If the TV is LCD the problem is either the lcd cable , or the video controller on lcd controller board.

    If this is a plasma then you need to test and eventually replace the lower buffer board and the ysus board.

    Are you facing this problem with both the cable box and Dvd both then the control board needs to be checkd for any burned components. If you are using RCA(three component cables) then try using HDMI cable.



    Please revert for any clarifications



    Thanks

The problem is your light engine is failing. The part number for this is UX22201DR and is available for purchase with the following link. It runs $334 dollars and really is a part that needs to be replaced by a technician due to the complexity in tear down to remove it. Please take a few moments to rate my answer. Thanks...

Our Samsung LN52B550 tv has a vertical bar of colored lines on the screen. We have unplugged and disconnected all signal sources. Any other suggestions?


Check the flat ribbon cables that connects with T'Con board to lCD panel for any loose contacts. Re-seat them. If this do not help you, replace the T'Con board.

Vertical blue lines appeared on the screen with no sound.


Hello,

All plasma an LCD TV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them, but it is very easy to wreck em. Good luck.
