Black Horizontal section on plasma (Occurs Randomly)

The top half of our Plasma turns black... Sometimes after 5 minutes of watching the tv, sometimes an hour after watching, or perhaps not at all. Very random. Most times if we turn off the tv and turn it back on, it goes back to normal. Hoping it's just a bad cable... any idea's? Purchased Feb '03 I believe and it just started doing this over the last few days. Panasonic TH-50PHW5 (50" Plasma)

SOURCE: Monitor goes black - green light stays on

My screen is black, why do I not have a picture?
Answer Antenna is not hooked up to television.

  • Make sure that the antenna cable is correctly connected to the television. If it doesn't work there appears to be no signal.
Problem is caused by television broadcast
  1. Push 'INFO' button.
  2. If the screen shows channel number (1, 2, 3, etc) try another channel. Not all channels broadcast at all times.
  3. You may have a signal problem. Contact cable provider or local broadcaster regarding the specific channel.
Television is in EXT or SIDE mode, and there is no external source provided, so screen mute (black screen) is activated.
  1. Push NEXT SOURCE button on the remote.
  2. On the screen appears all sorces.
  3. Press the UP button to switch to the TV mode.
If you are using an accessory device (DVD, DVR, or VCR), be sure the device is on and running.
Blank screen when connecting to the accessory (DVD, STB, PC) device via HDMI to HDMI.

Answer
  • Make sure the cable is well connected .
  • To check which connection is selected, Press the i+ button on the remote control.
  1. When you see Blue mute / blank screen and the i+ display does not indicate any video resolution indication then there is no valid signal detected.
    • Make sure the HDMI output of the accessory is valid by changing the video output resolution to a resolution which the TV can handle.
  2. When you see a blank screen and the i+ display shows a video resolution indication then the connection is correct.
    • The blank screen is caused by the accessory device and not by the TV.
    • To detect and remedy the problem caused by the accessory device, check the instruction manual of this device.
  3. If the problem remains : reselect the HDMI external source input by changing to the other HDMI input and back to the connected HDMI :
    1. Press AV on the remote
    2. Press up and then ok
    3. Press AV again
    4. Press down and ok
    5. The compatibility check process between TV and accessory device will start over again.
  4. Reset (switch off and back on) the TV and also reset the accessory device.

SOURCE: green interference on Panasonic TH-PX75U

Since the set is only 8 months old, it should still be under warranty. This may only be an internal connection problem, but opening up the unit will void the warranty. I would suggest that you call for warranty service. This is a problem with the set and has nothing to do with external devices or interference.

Keep us posted.

SOURCE: Samsung Plasma 42" TV - 2006

Hi, this is quite a common problem for plasma screens and LCD screens. The fluroscent backlight is more than likely faulty and would need replacing. The best thing to do is to take it to a service centre because there are no user servicable parts inside the plasma.

SOURCE: Screen lower half goes black/blank

The lower "Y Buffer" board is defective. Best repaired by a technician, or contact Phillips support for the part if you think you are able to replace a small circuit board on your own.

Plasma tv randomly goes black


By the highly technical manner in which you set forth the problem, I can see you are far more electronically savy than am I, BUT just a thought: Is there there any sort of timer setting in the TV menu which may be cutting it on and/or off, and which you have somehow failed to notice? Good luck. . .

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.

Samsung plasma ppm42s3 , picture wobbling,sometimes screen goes blank


Hello arunaik_6,

This looks as if a component has become thermally sensitive. The best way to find this is to use component cooling spray. It looks as if the problem is localized to the tuner section. Take the back off of the TV and turn the TV on, wait until the problem occurs and lightly spray the tuner section with the component cooling spray watch for any reaction, then if this does not work spray the Microprocessor and the LVDS section and watch for a reaction. The set should go back to normal when it does that section is the problem, try to localize the problem to one component. Then replace that component.

I hope this helps,

Thank you,

No picture, sound ok


I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.

Top half of screen blacks out


Today, after speaking to the Sansui Manufacturer representative from Japan. He stated that all you need to do is to turn off the closed caption from the TV remote and not the DVR remote. Black screen can occur at the top half or the bottom half of the screen depending on how it was originally setup during installation. Try this and hopefully this fixes the problem.
