BS3 screen not giving image. HELP - Xiaomi Black Shark 3 Questions & Answers

Hello. I need help urgently.
By the end of august, my phone's screen stopped giving image. I was playing and all of the sudden it lagged and turned pitch black. I took it to a technician and they told me it seem an LCD problem. I replaced the screen but that also didn't work. I replaced the LCD flex also didn't work. Lastly I bought another motherboard thinking that would fix everything but also did not work. The weird thing is that it does the charging sound, the touch sound when I place my finger on the screen but it just doesn't give any image at all. I don't know what's wrong and the technicians around my place couldn't be able to help me. I have some photos of the replacement parts I bought which work but don't give any image, just sound when I touch the screen.

This one is the LCD main flex replacement I bought, its the same as the original, a KLE-A0 . Tested before shipping it works.
This one is the 2 replacements screens. The one above is an LCD screen (stopped working suddenly) and the one below is an AMOLED screen. Both tested before shipping, supposedly work. (giving the sound but no image).
Replacement motherboard I bought less than 3 weeks ago, original. Also works. Tested before shipping.
I really don't know what to do, I have spent months trying to fix this. Please help me. If you need more info, I will gladly give out more details if neccesary.

I bought my replacement digitizer and screen from Vifocal on AliExpress: http://www.aliexpress.com/item/New-100-Original-LCD-Display-Screen-Touch-Screen-Assembly-Replacement-for-Oneplus-One-64GB-16GB-Smart/2039112357.html
It took 4 weeks to arrive by post, nicely packaged with a toolkit (but no adhesive strips or glue) and has the three tabs for the capacitive buttons - I haven't fitted it yet.

[Q] Motherboard Component ID

Hi guys,
My Verizon G3 took a dive out the car window and needs help. I bought a replacement screen, and I believe it probably works, but I'm not getting any image. I then noticed that there is a small component on the board that is broken. I was hoping someone could help me identify the part number. It is a small black piece right above the battery and below the ambient light sensor. I found the G3 service manual, and it says the part is U7303, but I am unable to find that anywhere, so I hoped there might be a number on the component itself that I could look up. Thanks for any help you can give!

Hi,
i think you will not get this part anywhere to buy, because it is integrated on motherboard. I recommend you to get a new motherboard or to find a broken G3 with working motherboard.
This is my choice good luck.

Yeah I think that's my option at this point.. I did find a snippet that refers to U7303 as a fixed positive LDO regulator, rp103k121d-tr part number, but there's not really anywhere I can buy that from without going in bulk lol.

Zenfone 2 ZE551ML Screen Marks

Hello everyone, if anyone can help me with this would be fantastic. I bought a Zenfone 2 last November on amazon, and recently it started overheating what I think caused some burned marks on the edges of the screen. I requested assistance from asus and they offered the RMA to fix it or replace it, but I'm afraid to be charged with CID ( consumer induced damage) since my phone have a lot of cosmetic damage. Should I take the chance with the RMA?

I had to RMA mine for basically the same thing (this thread). After hearing nothing from Asus for over a month I emailed them and raised hell. They responded and looked into it. They finally said that they were having issues getting the parts for it and offered me a replacement device which I accepted. My phone was in perfect shape except for the screen issue (used cases and tempered glass from day one) but it would be worth a shot. Just make sure you have a stand-in device before you send it, though.
Looking back I wish I would have just had it repaired by a local place. It would have cost me 80-100 bucks but I would have only been without my phone for a couple of days.

Could this be saved?

The screen has cracked for a very long time but still functional. Just now, it fell once again and then a white-ish thin line appeared at the very right corner, but I ignored it as it does not disturbed me. Few hours later, I think i put a little pressure into this pressure (But I'm pretty sure i am not, because my the only thing i did was to put it inside of my jeans pocket) and poof! Half of the screen cannot be seen clearly (refer picture). But still could function as in I could still use the touch screen mode at the affected area. Could this lcd screen problem be saved without replacing the lcd with a new one? Replacing it is my last resort if I could save it DIY. Help me, thanks!
Yeah, sure, via a software update. That'll also give you wireless charging, but only if you charge the phone inside the microwave.
You've cracked the screen! What sort of DIY fix you assume can exist, besides replacing it?
tired of cheap ebay screens, what replacement screen do yall recommend?
OnePlus RMA. It isn't overly expensive.
From memory, it was around £90 for me.

Help! Vertical lines on the screen

Hey guys, so I recently have a problem with my Mi Max 3 and that is there are vertical lines appearing on the screen. Long story short, it fell off my bed when I was sleeping. I found the phone beside the floor of my bed, the screen was facing the floor. Everything seems functional. But for some reason, when I press the “middle” of the screen or lock the screen (press the power button) the vertical lines almost disappear. Now I have researched the problem but I’m not sure. My question is, is something loose or broken? Or something else, comment down below, any kind of help is appreciated

Either the display cable popped off the board or the display ribbon tore off the display. One is fixable without parts the other needs a new LCD.
