    Panasonic 50VT65 Sparkling/misfiring pixels upper half of screen

    Recently my VT65 has started exhibiting sparking/misfiring pixels, it manifests as sparkling white pixels in the black area if there's brighter pixels in the same horizontal area (e.g. the smart viera boot screen, white credits on a black background).

    On inspecting the screen closley you can see pixels misfiring in the upper area of the screen at all time, it just gets lost in normal content.

    I've tried (without success) replacing the P/SS/SC board (refurbished boards) and re-calibrating the VSUS (including setting it to HIGH) but none has made a difference.

    The panel has about 18k hours on it so ideally I'd like to fix it. The generic recommendation for this seems to be increase the VSUS but it's already set to HIGH and at 218V (The max according to the service manual) so I don't want to push it much further.

    Any input on this would be most appreciated.

      Panasonic Tx-40cx400b top left half screen not displaying correct
      by armoured_smiler
      Hi,

      Trying to work out if this is TFT problem or TCon issue.
      The TV powers up but the top half of the screen, from the right it is OK, but as you look across to the left halfway across it starts get duller and duller until it is very dark on the lefthand side, currently I trying to clean the remote as it seems to have something film wise on the pads stopping it from registering buttons pressed.

      Also when changing the screen size of Windows PC display to say to a smaller pixel sizewindow, the original window displayin the top left stays/takes a few seconds to disappear?...

      panasonic TH-42PC77U plasma television half screen problem
      by renech
      hello,
      I hope someone on this forum can assist me.
      I have a panasonic TH-42PC77U plasma television.
      the lower 1/2 of the screen has become flaky....in and out, then finally goes black and you can only see the top portion.
      i have performed the reset to default settings quite a few times. Panasonic recommended..did not believe this would help...it didn't.
      I have removed the back panel and looked around for something obvious...burn marks in a board, etc....nothing obvious...
      I have read some posts that suggest the problem is related to the boards on the left...

      Whirlpool PACF212HP W portable air conditioner, upper fan only turns slowly.
      by spleenharvester
      I just acquired this portable aircon, history unknown. Its behaviour is quite strange:
      • When turned on and placed into cooling mode, the upper fan (cold air out) just spins slowly. The compressor and lower fan do not run.
      • If the device is then placed into heating mode and then back into cooling mode, the lower fan and compressor kick in and start cooling, but the upper fan still only spins slowly.
      • If the device is placed into fan-only mode, the upper fan does not respond to low/medium/high speed toggles - just keeps running slowly.
      • Display and buttons all behave normally aside from the

      Panasonic Plasma screen interference on left half of screen
      by Zelek11
      My Panasonic Plasma model P55VT50 has started displaying "interference" on just the left half of the screen only (left when facing the screen). Sometimes it's concentrated in about the first 30 seconds after startup, then disappears. Other times it's fine at startup and then randomly does it later on. When it flashes the interference it's very quick and doesn't stay on the screen unless it flashes repeatedly in a row.



      This image is a screen shot from a video I took. This is an example of the interference at its worst. Often the interference is much smaller...

      Panasonic TC-P55ST50 8 blinks then no blinks
      by Andre Gilbert
      Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
      Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
