lg g2 d802 hardbricked no logo or download mode just black screen with white lines

hello please help i tried to install twrp through autorecovery apk and after rebooting my phone just shows black screen with white lines
no download mode nor lg logo display
phone recognised as marshall london device by my computer

Screen showing random lines, then black, can screen replacement help?

Phone screen status:
On screen there are vertical lines in random colors, and if I press on the screen semi-hard it turns black( more force results in white screen). When I depress it return to partial visibility. By that I mean left most and right most part of screen is at most times black. Touch screen is working for the most part(can't pull down notifications, else seems to be working).
My question is will the sceen replacement solve the problem or is the damage more severe?
I cant provide pictures, don't have other phone :) If opportunity arises, I will post them.
Phone is sony xperia e4
Also, lets say that repair shops are too far, expensive,... :D

Tweaked Dha lines or Fha lines?

so I installed a custom rom on my Galaxy S6, and its asking me which tweaking do you want for multitasking: DHA lines or FHA lines?

So, I'm wondering which one is better to select, thanks.

White Lines across my smart phone screen

One morning I woke up and the bottom half of my Samsung galaxy avant (SM-G386T) had a grid of white lines going across it. First time I restarted my phone it went away.

But they keep coming back and now it's more permanent, Sometimes it goes away briefly but they come back. I tried factory resetting. That worked the first time for a few hours but then it came back. and I tried it again and 2nd time there white lines where there during the factory reset.

The lines even show when I turn the phone off and charge the phone. So I believe this means it is w hardware issue

I tried taking the back planel of the phone off. I disconnected and reconnected the lcd connector latch on the left side. But the problem still persists. I haven't pulled up the screen with a suction cup. So Idk if there is a cable that could be loose on the front end or not. But Idk want to go buy suctions cup if I dont need to you.

Should note that I do have a good sturdy rubber case on my phone. but it has hit the floor a few good times.

One other thing that seems to aggravate or sometimes even make the lines go away is putting my phone to sleep and waking it up repeatedly or adjusting my brightness to max.

What do you guys think? is this fixable or do I need to replace the lcd screen.
