Note 3 N9005 - No display when booting normally. - GSM-Forum

FShahid · 08-01-2017, 19:36

Hi, got Note 3 N9005 with a strange problem.
Keeps rebooting on 1st logo several times (up to 9 times or less) after that it seems to boot normally into home screen but with no display onwards (no display since 1st logo), but with sound, touch, etc all responsive, notification sounds led all works, but just no display.
When trying to reboot to recovery it shows booting recovery on 1st logo but it doesn't and same reboot, when charging it shows battery logo but then reboots to 1st logo and keeps rebooting as stated above.
But when in Download Mode, it displays perfectly with no reboot. Odin flash always success, flashed complete firmware, two different ones, still same problem.
Without LCD connector connected it always seems to boot fine.
LCD screen is clean, no drops, no visble crack, no physical damage, it just starts happening all of sudden after doing a restart from power menu within the software. Never happened before.

Need solution, thanks.

You must check with another LCD, before to do anything on hardware.

I do suspect it could be lcd issue but I don't have any, how can I somehow bypass it such a way that it doesn't reboot when display comes on (at the moment it shows 1out of 4 attempts, even the download mode goes blank in such attempts). Is there some testpoint or temporary jumper that I can put so that it boots with display (I already tried booting without lcd connector connected and connecting it when phone is in sleep mode, still no display). Once it shows display in software I will try not to power it off or reboot it.
Kindly help me in this case as I cannot afford to buy new screen.
I have the soldering tools and skills and also got the service manual for N9005.

hi
-with microscope ceck fpc connector on m.board and on display flat. You can to use solder iron for refresh the solder joint.
- ceck esd filters normally near to LCD connector.
- ceck caps and diode mounted on flat of the Screen.
