Hi,
I ve got my hand on a S4. It seems that the screen is dead but it could be more. I m trying to figure out if its worth to fix it or not.
So far I was able to put in download mode and flash stock rom BUT :
- I did not hear any boot sound after
- blue led flashing on boot
I then got my hand on an MHL / HDMI adapter. Connected to TV but got black screen (but signal detected).
Could it be that more than the screen is damaged ? Is there a way to see that ? Maybe a rom with ADB enabled by default ?
Thanks

Hi guys
Got a strange problem with my Galaxy S4 (i9506).
The problem is when I try to boot this phone, after Samsung logo there's only blue screen and phone becomes hot.
I think it's mainboard problem but not sure, because charging works, Download/Recovery modes work, I can flash ROM via Odin or Kies without any problems...
I tried to replace mainboard by i9505 mainboard and.. when the frame is not installed, screen works correctly, but when I mount a frame, screen immediately turns off. When I try to boot phone with frame, there's a green strap (?) for a moment and it turns off. Sound works, charging works too, download mode works.
Do you guys have any ideas what's going on?
Hi folks,
I replaced a broken screen (only broken glass for the optics-the touch and screen were working), for a new unit. After assembly, the screen work but the touch only till the first p'ower off' of the screen. So if I type the lock code set screen off time to 30min I can work on it - check setting, even updates, all is normal. But after I turn of the screen (timeout or button) and wake it up, the touch is not working (I can use the phone with usb mouse). After a reboot the touch is again working...
some ideas to check or how to fix it ?
Thanx Sleyo
Even am facing the same issue :crying: Unable to figure out whether its hardware or software issue. I tried to install TWRP recovery to check whether it is happening there also.. The same issue with recovery too. But if it is a hardware issue, why is it working until first screen lock.. So can anyone please help with this.

I ordered the LCD over ebay.com not original retailer - maybe that is a problem that it is different.
I also think there is no SW problem at all as U saying - if it does the same in TWRP it look to me clear.
Maybe some driver ? is there something in the Bootloader ?
I don't wanna order a new one wait 3 weeks just to realize it does not work and it is a HW problem of the mainboard.
The digitizer has definitely a problem to start UP after sleep, that's maybee a clue - the sleep mode of the chip. Has it some permanent wake up for som 'double-tap' gestures or so ?
Hey, I broke my op2 screen so I bought one from ebay, teared it apart all correctly (i'm a computer technician), installed the new screen, all fine but a weird symptom appears:
- It boots and shows the Oneplus logo then screen all black. I know it booted cuz the touch buttons work and i can ear the sound of unlocking etc. Also if i plug into the pc I can easily access its memory.
- If I try to enter recovery I know it enters too but the screen is all black, the only mode I can see the screen is fastboot mode and it stays and acts normally.
- I did a full reset on the phone back to stock via adb, thinking it was software, its all stock now, still the same occurs
Im out of ideas so I just think the screen is faulty from ebay, did this happened to anyone?
Thanks in advance
