Touchscreen Stops Working. Help! - Teclast X98 Air 3G

I flashed the bios to 2.02 and rom to mirek190 v7. It has been working beautifully until suddenly the touch screen stops working. I tried to flash the bios and rom again, but still cant get it to work.
Is this a hardware issue or software issue? Thanks!

[Q] Black screen after boot?

I have an i9000m which I had flashed to Froyo JPO with Odin, then installed Darky's ROM v 4.0. I had been using this for a while with no problem but a couple days ago it shut itself off for apparently no reason and when i tried to turn it on it would just get to the Galaxy S startup screen and then continuously restart and never fully boot. I could still get into download mode so I flashed back to the stock eclair JH2 firmware, but when I tried to turn the phone on, it would go through the normal boot sequence, but then i would be stuck at a black screen, with the bottom two buttons lighting up. I played around with flashing various different firmware versions, but it didnt help. After searching the forums it looks like it might be a problem with the internal SD card, but I'd like some other opinions/advice. Could anybody help me get my phone functioning again?
I'm having the exact same problem since today. It started out of nowhere; one moment the phone is working fine, the next its rebooting and it gets stuck...
Anyone got a solution besides a factory reset?

Mi 8 dipper Touch not Working -> Unplug display from motherboard and back in.

Hi everyone, i Have mi 8 global running latest miui 12 official.
I've never modded it before the issue and it was locked bootloader.
Here's the story:
After a screen replacement all was working well until i first shut down the phone and then when i booted it again the touch screen didn't work at all. I could perfectly see the images but touch didn't work and booting in recovery had the same issue.
How i managed to make the touch work:
1) Boot the Phone in System or Twrp
2) While booted unplug the display connector from motherboard and plug it back in
3) Touch works perfectly until i power off the device (and then it doesn't work again)
Also:
I tried various fastboot flashes and i found out NO MIUI Rom Fix the issue, except for this one (i didn't try custom roms): dipper_global_images_V9.6.7.0.OEAMIFD_20180903.0000.00_8.1_global_5671a55800.tgz
But:
-If i boot into System the touch works everytime perfectly even if i shut down the phone and boot it again.
-If i boot into Recovery (TWRP) the touch won't work so i need to unplug and re-plug the display connector to make it work, but after shut down it doesn't work again (it still works everytime in System).
Also:
I'm currently running this rom and i have random reboots (which never happened with miui 12).
Any help would be appreciated, thanks
