G73sw green lines

About 4 days ago my laptop started to show neon green lines on black areas when i booted up. So I looked everywhere online to see what it is and it could be a loose cable, bad motherboard or bad gpu. However, a few hours later it went away and it has been fine since then. but today, I was playing magic on steam when I notices the blacks slowly became green until the entire screen was filled with neon green (the games background is almost all black). I hope it isnt anything serious but I want to know if anyone knows how to fix it so I dont have to RMA and not have a laptop for 2 weeks.

 

Have you tried it on an external monitor?

 

yep i tried a monitor and it is fine. Also as i carried my laptop over to my monitor when i pressed the cover for the hdd's it got worse. So then I pressed around the bottom and it got better when I pressed near the rear fans. I know the lcd socket is in that area. So it might be a loose cable, but I am not thinking so. My gpu is running 60c idle with no load!!!!!!! not good

 

Likely a loose cable. The GPU running hot is a bit concerning. The Nvidia card typically runs cooler than the Radeon in the JH, so it is a bit high on idle. Not horrible, but a bit high. Have you cleaned your vents? It is also the middle of summer, what are your ambient temperatures? Would you consider repasting? If you do, you can fix that LCD issue too.

 

If the issue is what I am thinking, based on a couple years as a hardware tech, then you could have a bad video cable, you could also have a failing LCD panel. Would it be possible to take a photo of the issue and post it? That way we all know exactly what it is you're talking about. Recently ran into a situation where someone said they had lines on the display, but what they had was GPU artifacting. It resulted in their unit being sent back NTF the first time they sent it in for an RMA because the techs were looking for an LCD failure.

Also, just to be clear, if your unit is under warranty and you attempt this repair yourself, you will void the warranty. I will not tell you that you cannot do it yourself, but just be cognizant of the implications of doing so. It is not really that difficult to tell if a unit has been disassembled before for a decent hardware tech. You just can't replicate the same torque level on screws by hand, and a dozen other little things. So make sure you do the pro-con analysis before putting screwdriver to screw.

 

Ehh, its been most everyone's experience in here that warranties don't get voided so easily.
