    LCD Monitor Service Menu

    Hi!
    I am reparing a 15" LCD monitor which is using a TSUM15AL-LF-1 MCU IC, the problem with the monitor is that "display is dim", contrast control dosent work, where as the Panel CCFL and inverter board is ok, have checked it with a good monitor.

    This monitor is of indian brand "HCL", but made in china, OEM i guess.

    Do anyone know how to display the service menu. And what can the problem with the monitor, i have googled for the service codes, no hope..

    No datasheet of the TSUM ic, i heard its a topsecret ic.

    Attaching a pic of the controller board.

    Thanks.

    Please help...

        HannStar Hanns-G HC194d LCD monitor repair
        by momaka
        Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

        How to access Vizio m652i-b2 service menu
        by tusiime
        The current main board on my Vizio m652i-b2 only has 1 of 4 HDMI ports working. Also, the coaxial port is not working.

        So I ordered a replacement board. It boots up the tv, but the display is dark in areas, colors are off, etc. I have seen information online that a setting in the service menu may need to be adjusted. Have tried many ways to access the service menu using remote codes, but none work.

        Can someone here provide the confirmed method for accessing the service menu on this tv? Thanks in advance!
