    Samsung UE48J6200K - No image but sound
    by Francesc V.
    Hi:

    This TV turns on and it can show picture for some seconds (sometimes minutes) then picture freezes and fades away. What I've seen so far is that the T-Con (BN41-021101A) starts with three leds on, but as soon as led3 turns off, just 12V and 3.3V (the bold ones) remains in the PCB but all others disappear.

    If I remove the 2 bellow ribbons, LED2 never turns on. I was trying to look for the "T-CON ready" pin to shorten with 3.3V and then test just the TCON without the panel (haven't found it yet)

    Not sure how to proceed here..............how can...

    LG 42LN540V LED Backlight Flickering After Replacement When Connecting The Screen
    by RetroComputingGrotto
    This TV has been on the wall in our reception area for around 10 years and the other day the backlight failed. You could see a feint picture so we knew the screen was OK. I took the TV apart to get to the failed backlight and inject voltage in to each half of the LED strips to identify which ones had failed and 4 needed replacing. I ordered a set off of Amazon and they arrived the next day.

    On fitting the new LED strips I plugged in the TV was blinded by the light!!

    hello
    The laptop is turned off during the BIOS update and it turns on with the attached BIOS and works properly, but without battery!
    If I connect the battery after turning on the laptop, the laptop works correctly with the battery, but when I turn off the laptop, it only turns on again if the battery is removed and the BIOS of the laptop is reset....

    Apple MacBook Pro A2141 16" IC BYPASS
    by oxonater
    Hi everyone hope all are well

    I need a little expert advice on a issue I have and seeing as this forum is full of clever people I thought ask here as you never know.
    I recently repaired a logic board 820-01700 which belongs to a 16" 2019 Macbook Pro, however I seem to be missing a component near the T2 Rom chip and is U4730.

    The schematics say this chip is (M34128-FCS6_P/T) and it also says there is a bypass for it wondered if anyone come across either the IC or the bypass method.
    I suppose it's worth noting googling the part package brings up various...
