    Plasma display with 2 issues

    I recently came into a Pioneer elite 1000HDI display.

    The device functions pretty well but has two noticeable issues.

    Firstly, there is a region of the screen towards the right side in which the highlights are tinted cyan/green. The affected area is centered about 1/5th of the way in from the edge, and just above the vertical center, and the green tint fades out from this point.The bottom right corner is not affected.
    In dark scenes it is not perceptible, but on an all white screen is it very pronounced. This is the issue which bothers me, and I wonder if is fixable.

    The screen has another less troublesome issue which I am also going to detail in case they may be somehow related. The top center of the screen occasionally gets blown out, blocky and pixelated. This only occurs in very specific circumstances, and very rarely. Particularly underwater shots aimed towards the water's surface are the most likely way to reproduce this issue.

    I appreciate any help in diagnosing this issue, and while I hope it is repairable, the unit is still acceptable in its current condition. My wife doesn't seem to have noticed either issue.

    I have attached an illustration (not a photo) of the issue as it appears on an all white screen. The intensity of the tint is exaggerated.

    Re: Plasma display with 2 issues

    Ok, the second issue I have determined after further observation to be the commonly discussed "sparklies" issue. The cause and remedy however, I am still hazy about. Does the localized nature (top center) have any bearing on troubleshooting actions?

    Is this possibly related to the more prominent malfunction I have described?

      Dynabook Satellite Pro C50D-B-100 - BIOS Issue, Black Screen
      by wizard13
      Hello everyone,

      I am experiencing a BIOS-related issue with my Dynabook Satellite Pro C50D-B-100. When I power on the laptop, the screen stays black, and there is no response from the system. I suspect a corrupted BIOS.

      I have checked the forum and the available documentation but could not find a solution specific to my issue.

      Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
      by Ryan.man
      Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

      My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

      This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

      HELP - Contrast/brightness issue with subtitles on screen
      by cloudy
      Hi everybody
      Since day one I'm having an unpleasant contrast/brightness issue on my Asus laptop.
      Basically while watching movies, if subtitles appear on screen, the contrast or the brightness of the entire screen increases a lot (not sure if it'is brightness or contrast), disturbing the viewing of the movie.

      Last year I replaced my screen because got damaged and this contrast/brigthness issue persists. It happens only on the laptop screen, in fact If i plug an external HDMI screen the issue does not occour on it.

      It occours both on ubuntu and windows...

      Panasonic Plasma TH-50PZ85U No screen No blinks on red power light
      by Alicat
      Hello,

      Stopped by this site trying to fix my parents Panasonic Plasma TV.

      Model number is TH-50PZ85U

      Power comes on and the red power light stays on solid.

      Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.

      I also hear a few clicks.

      I also think my parents said there was a thunderstorm and the TV failed after that.

      Section 6 in the service manual talks about power and no screen,...

      A1502 screen only issues
      by aazjo
      I have a MBP A1502 (early 2015, 820-4924) with a screen that will not turn on. I have swapped screens with a cracked test screen and the computer boots and the cracked screen works for both backlight and image. The black/blank screen appears to do nothing.

      I have collected resistant data from the cracked screen connector pins and submitted to OBData server:
