I was using my tab and browsing some website suddenly half of the display turned black and white and the other half working as usual.. i reset my tab several time but the problem is still there.. i have no idea what is happened…
Hi @zakariasabuj , Was the tablet dropped, bumped or get wet at all? As a DIY repair the only thing to do is to first open the tablet and check if the LCD display flex cable connection to the systemboard is OK and if it is, then to temporarily replace the display assembly to check if the problem is with the LCD display or the systemboard. Here’s a video that shows how to dis-assemble the tablet which may be of some help If it is the LCD screen that is the problem, search online for Samsung Galaxy Tab S4 LCD digitizer assembly to get results for suppliers of the part. A brief online search revealed that it is not cheap.
Has it been dropped at all in the past? It sounds like you damaged the LCD screen or possibly have a loose connection or a dirty connection. I would open it up, disconnect the battery and disconnect the battery. Disconnect the the screen and clean the connectors with a qtip and alcohol and a soft brush. Try that and see if it helps.
The tablet amoled or flex cable is faulty i have similar problem, I try all the things(downgrade rom&custom rom) and i have the board verified by 3 services and the board is fine the best option is to buy another second hand tablet or new one Me i buy one second hand with 120€
