    Jvc kw-avx700 dvd

    Hi guys, has anyone got any info on how this dvd unit actually works. Cut a long story short I bought it from Ebay Uk and it didnt work as it should, got a refund and guy let me keep the unit so it would be great to get it working as the build quality is out of this world , typical Japanese electronics.

    The fault it this:-

    Screen works and volume but thats it. Remote does nothing. I found a small micro switch has broken it seems to sense when the screen is in the closed position. All the unit says is "Screen position Error please press open button". The buttons down the right hand side are dead when screen is in any position. Bridging whats left of the micro switch doesnt do anything either

    Funnily enough if I press the DVD eject button the screen starts to move in small increments one way which is bizarre?

    Id love to fix this unit so if anyone has any idea on how it works or where to start id love to hear from you. Its very sophisticated and appears to have a hall sensor and a toothed track to determine screen position. It is relatively easy to scope the sensor if needed.

    Thanks in advance

      Have you checked for bad capacitors?

      Have you checked any voltage regulators, to make sure they are working properly?

        ThinkPad P15s Gen 1, NM-C931 REV 1.0 touch screen replaced only works in UEFI menu
        by Yehuda170
        original screen was BOE NV156FHM-T07 with On-Cell Touch screen I²C

        replaced with what was in my stock, which is IVO R156NWF7 R2 which is also with On-Cell Touch screen I²C

        now touch screen works perfectly in UEFI BIOS menu & boot menu. but not working in OS, tried windows & linux too

        with original broken screen i can see in device manager touch screen in human interfaces

        but with the new screen it's not showing in device manager

        is it lenovo blocking it? is it driver missing?

        I²C is a headache

        MacBook Pro A2159 - No Display / Works on External Screen
        by Ado02
        Hi,

        I am working on a MacBook that came in for a screen replacement. The MacBook powers on and works on the external screen. However, the screen stays black. The replacement screen made no difference. On further investigation, I found small amounts of corrosion.

        Please see the attached image.

        I ordered a refurbished logicboard, but the problem didn't go away with the old or replacement screen.

        Can anyone suggest where to go from here?...

        Samsung UE55JU6800K half screen dark
        by Chrissygizmo
        Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
        I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...

        Acer Nitro 5 AN515-54. displays on the external monitor and works fine, the issue is NO display on the internal screen
        by DqMagetz
        Good day!
        I have a customer's laptop — Acer Nitro 5 AN515-54 (EH5VF - LA-H501P). It has a display on the external monitor and it's working fine, but the issue is NO display on the internal screen. I already replaced the eDP cable and checked the LCD connector pins.

        Here are the voltage readings:
        • Input – 19V (stable)
        • +LCDVDD – 3.3V briefly, then drops to 0V
        • EDP_HPD – 3.3V briefly, then drops to 0V
        • PCH_BKL_PWM – 2.2–5V briefly, then drops to 0V
        • EC BKOFF# – 1.8V briefly, then drops to 0V
        • PANEL_OD_EN – 0.3V

        Is it possible that the EC chip is corrupted or damag...

        Vizio TV M50-C1 reboot cycle and static on screen
        by spice_disc
        I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.

        The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While...
