[Help] - Change R3 LCD to R4 LCD 3D Blank Screen

Help me guys to fix about this.. When i change to r4 lcd..i start the lapt0p and hearing 7 beep with blank screen.. When i change back to my old one r3 lcd..still blank screen and i can hear os startup windows..please help me..

 

Now the 7 beeps are gone,im facing with blank screen,and my gpu fans not running..i just can hear the sounds of windows startup only..no display

 

Did you plug it back into the correct slot? There are two places you can plug your LCD ribbon into. The 3D model HAS to be plugged into a specific one. I don't remember off hand which one it is.

 

yea you probably plugged the ribbon cable into the correct slot or you will get the issues you are describing.

 

Both slot are different type of connection. The 3D cable has two screws , that need to be screwed down on the connector whilst the regular is just a plug that plugs into the regular slot. Something else is wrong.

 

yeap guys... i mount the cable into the slot which one has a two screw attach on it .. from what i know, 3d model has a 4 cable include Wireless antenna .. 1 for 50 pin, 1 with white socket pin, 1 more coming with black socket pin...just only appear alienware text light below the LCD and keyboard light...screen still black and no display..

 

- eDP connector/cable 50 pin, 60Hz 40 pin (LVDS) so you'll need a different cable/connector.
- 3D Vision emitter cable (Black)
- Camera/Microphone (white)
Display is set to PEG ? reset the BIOS (remove CMOS), Display SG (60Hz) to Auto (BIOS reset) then set it permanently to PEG.

Edit: Samsung 3D R4 screen seems to be 40 pin, mine R3 3D LG screen 50 pin with the R4 motherboard works perfect, we should swap screens then - I've PMed you.

i mount it with perfect connection .. but what the result is, no backlight from my LCD .. i assume that was a blank, but when i try using my phone camera lighting, i saw windows there with no backlight... so what cause of this problem guys?
i don't know what to do now, is that mean problem with my MOBO or whatelse ..? i try to change back my origin LCD m17xr3 .. no backlight , still black .. i can hear windows os startup sounds, i can see windows behind there...but no light from that LCD .. very frustrated ..

 

With the stock screen (LVDS connector/cable 40 pin - 60Hz screen) reset BIOS, remove Battery / CMOS.
