    Panny TX-42AS500B upper corner of screen flickering

    Hi Guys, hope you are all well.
    I recently diagnosed some bad LED strips in my Panny TX-42AS500B, after I had the standby light code flashing once every couple of seconds. These have now been successfully replaced and now the TV turns on as expected.
    There seems to be a secondary issue of the upper right corner of screen flickering.
    This only happens intermittently and when it does happen it has taken a few minutes for the issue to occur once the TV is switched on. When I turn of the TV the flickering seems to subside. Like I mentioned, this seem to be an intermittent issue.
    Any suggestions would be greatly appreciated and thanks for taking the time to read this post.

    Cheers

    Did you test leds when you replaced them and none were flickering?

      All original and replacement LED's where working as expected. The TV has been on for about 1 Hour now and no flickering. TV was unplugged and powered off for several days whilst I waited for the replacement LED strips. When I replaced the Dead LED strips and reassembled the TV and plugged it into the mains and turned it on, the intermittent flickering seemed to manifest after several minutes.
      As of now there has been no more flickering, but I am still concerned it might be a failed component that originally made the LED strips fail in the first place and might happen again.

        Just a quick update: All seems to have settled down and the flickering has disappeared.
        Still wondering as to why it happened to begin with, but fingers crossed its sorted itself out.

        thanks all

            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

            ACER BM320 Monitor - Horizonal Flickering Lines After a While
            by reessi
            Hello,

            The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..

            They are black on the right and gradually fade to nothing on the far left.
            They start either after 5 mins or up to 2 hours after so annoying for testing.
            They flicker continuously very fast! With a slight pause milli-second every second.

            Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.

            I tested each half by removing the first the left flex from...

            Fixing an I-Inc IF281D for the 3rd time, now with added flickering!
            by DrvLikHell
            Hello everybody! It's been nine years and I'm back again with the same monitor that several people here helped me fix back then. The first time, I replaced two caps as was recommended here and the original problem was solved. Then it started acting up a few years later and I came back for a parts list and replaced a few more caps (I didn't make a post about that and don't remember which ones), and again the problem was solved. This time, however, I'm not sure if it's caps.

            The monitor stays on but certain colors will flicker. Generally it's darker colors like dark greys or dark blues,...

            Problem

            This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....
