Asus G73jh weird LCD colors! Lcd or lcd cable ?

hi i installed the hd 5870m from alienware and it worked like a charm but the colors are weird and text is kind of blurry ! i changed the cable when my original one got damaged and when i changed the cable while installing it i damaged the board and GPU too so i dont know if the new cable is ok or not i bought it home as it is ! so today as i have replaced the motherboard and the GPU(dell's hd5870m) i cannot see the colors properly as i am attaching photos for u guys to tell me if it is the lcd or lcd cable ?need suggestion guys

NOTE:when i connect it to the external monitor the colors there are perfect as normal ! so the GPU is OK

 

One more ! !

 

Definitely seems like the cable is not connected properly or something is wrong with the cable itself. The second picture actually looked like physical damage until I realized it was most likely the pattern on the screen.

 

hey thanks for the very quick reply ! actually the cable is properly connected i am having the lcd removed from the case and the laptop disassembled at the moment... i have applied pressure too on the the sides (the lcd's and the motherboard's side) but still same !

 

Yes colour issues like that are usually not the panel itself, what does the bios look like?

 

i will add the photo of it in bios and show it to you ...its type of blurry ! will post the photo today

 

here you go

 

Did you try hooking up an external display? Certainly firmware/hardware related rather than software.

 

yes i did and there i get perfect picture quality

 

This is very likely a screen problem, possibly its driver board.

 

i re installed the driver but no luck ! well tomorrow i will go to the market and buy a new lcd cable and see what i get in result

 

The driver board I was talking about is part of the LCD screen itself.
It might be that, or something else.

 

ummm but i guess its the cable because my original one which is damaged when i plug it and compare with the new one ...the colors are much better and text is readable as compared to the new one ! i have ordered a new one ..lets see what happens now

 

Yeah, if it's just the cable then it will be an easy fix.

 

yeah waiting for the cable and see the result eagerly lol

 

UPDATE : Tried 2-3 new cables and a NEW LED too ! but still the results were same ! i read at this page that the guy EVGASR2 was having the same issue of weird artifacts and colors but he was having heat up issue too but i am not having that ! he flashed the card to A00 i guess ! and i dont know how to do that ! i hope someone can help me out with this problem as i am only able to use my laptop on external display !

 

UPDATE 2 : Got the internal LCD to work flawlessly without any problems ! flashed the vbios of Dell's 5870m of A00 revision ...the old one was A01 which had issues in alienware same as mine with the internal display colors ! now as i have flashed the A00 revision its working perfect but the fans are still at full RPM ! well atleast i have got one great work done

 

Oh wow, so the new VBIOS A01 had issues, but did you update from A00 to A01 previously before the symptom occur?

 

actually my original asus's 5870m died i dont know how ! so i bought a used as it is dell's 5870m ! in the start i thought my lcd cable is damaged because on external display it was showing proper colors except on internal lcd ! so i ordered a new lcd cable and tried on that but it didnt work and then i read on alienware's thread that its the issue with the REV A01 compatibility with G73jh ..in order to make the laptops's internal lcd screen u have to flash the Vbios of A00 to make it work and thats what i did ! i can provide the vbios if anyone want it ! well since i have attached my internal display i am noticing strange behavior of gpu clocks ! on battery they dont go up more than 300 core clock and 400 memory clock even if i turn on a game ! i have edited the power management profiles but not luck ! and whenever i connect the charger with the laptop the gpu clocks go to 405 core clock and 1000 memory clock and when i turn on the game it goes to 700/1000 and i can play nicely ! dont know what the issue with the battery mode !

 

Cool, glad you got it working. When installing a new GPU display issues can easily be firmware related.

 

yeah i got to know that when i searched alot about dell's 5870m ! well atleast i want the hdmi port to work properly :/ dont know how to do that

 

That's a lot trickier due to the murky world of HDCP.

 

trickier but not impossible i guess i wanted to know how to do that if someone has a clue or can help me with it ! i will be very thankful to him
