There is faint vertical green line on the screen

Since a few days there is a green vertical line on the left side. Although is very thin (1 pixel wide), it is very distracting. Sometimes appears and sometimes doesn't.

Could it be a LVDS cable issue? or perhaps i would need to replace the full LCD.

Could someone help me please? Whatever it is, i will try to fix it myself.

Thanks a lot

@v0lc0m a single pixel wide line is most commonly a tab error. That is where the bond between the small ribbon cable and the panel has failed. Sometimes the line will disappear for as long as you apply pressure at the tab that is located where the line is. This usually requires a replacement of the panel and cannot be fixed by the normal DIY'er.

@oldturkey03 - Did you note the Moiré pattern on the last image? I suspect there's some stress on the LCD panel (bent frame) He might be able to loosen the LCD a bit which might relax the tab connection.

What do you think about Dan thoughts @oldturkey03 ? I could upload more pictures if you want.

Actually, I wanted to take some more pictures right now and there is no line so far.

So, what tutorial would you recommend me to fix it eventually?

@v0lc0m I am certain this is a TAB error. Anything else can only be determined by removing the LCD display and checking the TAB's

@oldturkey03 - Your right, its a tab error! No question about that!

I was thinking the stress of a bent display frame maybe the cause they pulled away and relaxing it might allow it to touch down the few pads that are disconnected.

@v0lc0m - You'll either need to live with the line or replace the display. If you think you're going to replace the display it might be a worth the gamble. What is there to loose?

Did you bang or have something heavy sit on the lid? Or did something get wedged between the lid and case when you closed the lid?

@danj Actually the laptop was bought refurbished. So, this could be the issue. They could had fixed something inside the panel and left some tab connections wrong connected. The warranty is gone, so I need to search a solution by myself.

I didnt put anything on the lit.. just once a screen protector very carefully and I already removed it

@oldturkey03 Could you recommend me a precise tutorial to dissamble the LCD display and checking the TAB's precisely?

Is replacing TAB connection itself impossible?

@nabuchodonozor - Sadly, a TAB error is a bonding issue between the LCD Glass to the flex cable to bring the signals from the logic board. Often the conductive metal oxide coating on the glass fails either cracking or lifted up.

Time for a new display ;-{

@danj So can't you just reconnect ribbon cable to display ? It can be done without bonding machine

@nabuchodonozor - Yes the internal display is damaged!

Somethings are just beyond what we can fix! This is the case here.

If it bothers you you'll need to replace the display assembly: 15" MacBook Pro 15" Display assembly, Apple P/N 661-5847

@danj Not always ! Sometimes it's just faulty ribbon cable ! You can re-attach it to both display and t-con board

@nabuchodonozor - A single pixel wide line is a TAB error!

As I explained the issue is deeper within the display "bonding issue between the LCD Glass to the flex cable" You can't replace it and the issue is one of the very tiny .10 mm conductive metal oxide coating traces on the glass fails.

Here's an example os can see the issue: 2.5" display the interface is the bond between the LCD glass and the ribbon cable.
