    Nintendo Switch HAC-001 - No picture, momentary backlight

    Hello,
    Nintendo switch, board HAC-001. The back light comes on and then goes off. After the reset, you can see the backlight all the time, first brighter, then dimmer.
    The console came to replace the SD card slot because the customer burned it with a soldering iron and it was full of flux everywhere. By the way, he melted the blockade of one flex, but it is rather irrelevant. I am completely unfamiliar with this type of equipment but the replacement seemed simple.
    After desoldering the socket, I reassembled console to check if it starts, and it doesn't. It was working before, but not after the connector removal. I was looking for something in the circuit at the screen connector and measuring the resistance on one coil I found a short circuit. It seems suspicious to me because it is quite far from the place of soldering, besides I did not overdo it with the temperature (350 *C) and I made myself a protection of aluminum foil and Kapton tape around the connector, but I did not remove the emmc memory. Did I damage memory? Did I overheat something? Any suggestions?
    Thanks

    I did radical cleaning of the old flux after the customer from connectors and it works.

        UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!
        by triplefour
        this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
        i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
        unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
        according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

        Micro Momentary Push Switch?
        by Natob82
        Great to be here! I'm a newbie here trying to find a "micro", momentary push switch to repair a Sony "clamshell" video walkman. This micro switch has long since discontinued by Sony, however I hope there are third-party switches of the same size and functionality that I might be able to source to play the same role. The purpose of this switch is to tell the video walkman that the user has activated the mechanical tape eject button, turning that physical action into an electronic signal that tells the tape transport mechanism to open so one can load or eject a video tape. I...

        Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
        by TR103
        Hi, I have a Samsung UE50TU with:
        - sound and backlight, but no picture
        - when it arrived, it had a picture for a few seconds
        - it keeps rebooting
        - without ribbon cable between the two panel boards, it does not reboot but I have no picture
        - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
        - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

        - without cable between mainboard and lcd panel and with a jumpered...

        Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
        by Mgiffune
        I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

        I ordered a supposedly ‘new' Tcon board this time, and
        ...

        Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
        by Ierwin
        Hello everyone,
        Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
        The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
        He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
        I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
        Anyway I still fully expect that there has been something seriously damaged...
