    Re: Samsung LE40A558P3FXXU Colored lines

    5 min. seems ok, i don't know well but i guess 99% it is not that chip the problem, since the Avdd is OK, the tcon has correct values, now your only posted picture of defect is too dark and little to undersand well, you annex the photo in the wrong way, check the other method to upload them bigger and mora than one, as ALWAYS, connect a source to see a more complex video signal than a poor tiny window..

    i guess you don't have an eprom programmer and knowledge in using it.. if yes it is possible to command the service menu functions through serial connection, it is useful a test pattern, anyway i guess 90% panel problem, the other 10 a tcon processor desoldering.

        Samsung Series 9 - BIOS issue
        by Kjell
        After installing Linux, I can no longer enter the BIOS of my Samsung Series 9 (NP900X3C) laptop. When pressing [F2] during boot I simply get a black screen. Same thing when pressing [F10] and choosing "Setup" from the "App Menu" tab. Apparently this is a relatively common issue with Samsung laptops of that generation, but unfortunately i haven't been able to resolve the issue (yet).

        Things i've tried so far; reinstalled Windows 10, checked for redundant boot entries, tried to factory reset using the emergency keyhole, attempted to clear the NVRAM by physically...

        Samsung SyncMaster 740n Phase Control Issue
        by vincentedel
        Hello,
        I'm having an issue with the Samsung 740n's phase control setting. When I use the automatic adjustment, it sets the value to around 54 (with a range of 0-100), and the picture looks clear and sharp. However, after some time—like after playing a game—the text starts to look blurry. When I auto-adjust again, it may increase the value to 80, and everything becomes sharp once more. Yet, after a while, whether it's a few hours or a day later, the same blurriness returns, and I have to adjust it again.

        I'm using the Samsung 740n monitor drivers instead of the default plug-and-play...

        QE65Q800TATXXC Samsung TV Issue
        by Manucsl
        Hello.

        My TV is a QE65Q800TATXXC Samsung TV.

        Issue : When you plug the 220V, voltages are OK on the power board and you can hear the click from the relay, but TV is not starting when power button is pressed. Red led is blinking when you press power button. But no images or sound ( Back-light is off )
        Then if you disconnect the cable from the main board to the power supply, the TV back-light turns on.
        Any ideas to check would be very appreciated 😊

        After reading some posts on this forum, I suspect an eeprom issue so I bought a CH341A to dump...

        LG 47LV5500-UA Vertical Colored Lines/Alignment Issue
        by Superluminal
        Hi all, looking for some input on this one. I've been reading the forums for quite some time but this is my first time posting for help.

        LG 47LV5500-UA
        10 years old
        20,000+ hours on it.

        Watching TV on it last week and right while I was watching the image suddenly started experiencing the symptoms in pics. Rainbow chromatic vertical lines and alignment issues. The issue is uniform across the entire panel. It does not come and go, the symptoms are stable.

        Here is what I've tried so far:
        - Factory reset and cycle of picture options....
