    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    ...

    HP Elitebook Screen blank - backlights but no image
    by dicky96
    Hi guys
    I'm trying to fix this laptop screen

    Basically the owner is a computer shop and they brought it to me with two screens. They said the repair shop they use could not fix it, so I thought i would try to see if I am better than their current repairer!

    OK so I have the original screen which works but has lines across the bottom quarter of the screen

    I have the replacement screen, which they fitted and it worked. They then put the laptop on one side for a couple of weeks until they found a buyer. When they showed it to the buyer, the screen would...

    HP Elitebook 8440P - Blank Screen, Caps lock and Number lock flashing
    by dicky96
    Hi guys this laptop has a bit of a history. Someone else has tried to repair it. When it came to me it was partially dismantled and has a new screen fitted

    The owner says it worked for a while after the screen was fitted, then the screen started to go 'funny' but I didn''t really get to the bottom of what they mean. They said it works with an external monitor

    What I found is, the screen is blank, it has backlight but no image and after a little while the backlight goes off. I don't get an image on an external monitor.

    All the leds are lit up and I cant...

    Lenovo IdeaPad Slim 5 14IAH8 - Type 83BF OLED Blank screen
    by Kalman27
    We have a Lenovo IdeaPad Slim 5 14IAH8 - Type 83BF for repair. The original issue the OLED screen is blank.

    We have replaced the OLED screen with the exact model, also we replaced the LCD cable, but no luck.

    I think there is something with the motherboard. I don't really have experience with OLED screens so far, so not sure how it should work. I have seen some laptop comes with a separate controller board, but this model does not.

    Also, there is an error in Windows device manager - This device cannot start (Code 10) - Intel(R) Serial IO I2C Host Controller...
