    Samsung t220 problem

    Hello!

    Main problem was that some menu push buttons "lived independent life". I changed the "up" and the "exit" button, now that part works fine.
    Right now the menu system is stable but the monitor turns off and on and off and on continuosly.

    The monitor's on/off switch is a one touch button between the monitor controller board and the menu switch board. If I plug out the menu switch board from the on/off board the monitor works fine. No turning off/on. So the power button should be OK.

    Any ideas?

    Thanks

    Samsung LU32J590UQUXEN Monitor display problem
    by CptChronic
    I have an intermittent display problem with my monitor, when I plug in the HDMI cable to my (or any) laptop, you see the connection screen shrink on the laptop as it usually would before displaying on the monitor but 95% of the time the monitor display stays black.

    Before it cut out all together, tapping the monitor control button a fair few times would make the screen display, and everything work fine.

    But now it never does it. Not sure what's going on, hoping someone can help. I'm capable of stripping the thing down and soldering in new parts if needed, or programming...

    TV Samsung UE55HU8500L (2014) – service menu + firmware reflashing advice needed
    by Robby-Gr
    Hi all,

    I’m trying to recover a Samsung UE55HU8500L (curved UHD, 4K model from 2014) after replacing the panel. The new panel is a 55A1UU8EH, which produces excellent image quality — very close to the original.

    However, since the swap, the TV enters a boot loop (Samsung logo → restart) unless I enter the service menu and perform a reset.

    The service mode had been previously modified — possibly by a technician or during the panel swap — and I suspect some key settings are mismatched for the European (Greece) market.

    Additional issues:...

    Samsung monitor Installed 1 cap wrong, now menu button dead, "no signal detected" msg
    by glutton4punishment
    Samsung synchmaster 226BW.

    Before I replaced 5 caps, the screen was dim.
    Sometimes it wouldn't turn on.

    I opened it up, and found 4 bad caps in the pwr supply section.

    I unfortunately installee one backwards, i.e. wrong polarity.

    When I turned it on, I head a loud pop, and I quickly shut it off.

    The replaced caps are 3 860uF 25V's, and 1 330u 35V.
    One of the 860uF blew.

    I didn't have another 860uF at home, so I tried it with a 1000uF 35V cap (I remember the reading of the 1k uF cap was close...
