Powers on but no picture

Hello! I am hoping to find someone who could help me figure out why my tablet screen is not working. The tablet itself turns on but it does not show anything on the actual screen, it is just black. So far, I have had the screen and the circuit board to it replaced as well as getting a techs opinion on it. They told me that I might as well buy another and that there isn't anything that can be done. I have already bought another one but I'd like to know if there is anything I can do to salvage the one that is messed up.

Hi @davesr ,

Does it also do this with the charger connected?

It seems very strange that replacing the screen and the motherboard did not solve the problem as there is not much else in there that affects the screen unless you used the original LCD ribbon cable that came with the tablet.

With the tablet on, try shining a torch at an angle close to the screen and check if you can detect any images at all on the screen. They will be very faint if they are there so trying this in a darkened room may help.

If there are images then there is a backlight problem but as you have replaced both the motherboard (which controls the backlight power) and the LCD screen then all I can think is that it may be the LCD cable (if it was the same one) or that one of the replacement parts was faulty or the wrong one or perhaps the battery is faulty and it can’t supply enough power to turn on the screen and run the tablet.
