Is my GPU dying?

[SolRayz]

I am getting this graphic glitch at startup wherby 2/3 of the screen is grayed out. It started happening right after having my LCD replaced for the third time. I cannot reproduce it as it is intermittent. It seems to happen on a cold boot but I can't be absolutely sure becuase it has happened before after waking from sleep. It happened to today after bootup, but being a little pissed I banged the side (not hard) and the glitch went away. Possible bad ribbon cable connection or dieing GPU? Anyone?

Take it back.

And dying is spelled wrong .

oops thanks and fixed.

My only concern is that if it is a GPU issue they may come back to me and say my logic board should be replaced. My warranty has just expired and I was abroad for the last 4 months with no problems and no ability to buy Applecare. I can't afford a new logic board. The freakin thing is barely a year old...and three monitor replacements since, the last one being a few days ago!

I have an appointment in a few hours...we will see.

Not a GPU issue. Most likely due to loose ribbon cable since a little movement can get the thing working again. I am not sure of the internal layout of the macbook pro, but being an asus repair tech, that would warrant a replacement of the GPU card at the most. Not logic board.

Do you experience the same issue when connecting your mbp to an external monitor?

i should also mention that I have on two occasion over a two month period...the last being a few days ago had the sleep/wake issue where the monitor fails to display anything (totally dead, no backlight...nothing). Maybe completely unrelated but this seems to be an issue with quite a few people and apple is not addressing it.

update

So they are saying that it could be the LCD inverter board but they will also replace the logic board. Hmmmm what is going on here. And I am out of warranty too.

So are the replacing the inverter and logic board for free? If they are did they tell you why?

 

[SolRayz]

That was my question. Is it the inverter board on the lcd or is it the logic board? From what I gather they are replacing both the lcd (again ) and the logic board at no cost to me. Genius boy could tell me nothing more than that at this point.

The black screen, etc can be caused by a faulty logic board and/or inverter.

as for the original problem, it looks like a bad cable or faulty lcd panel. Is this a 1st/2nd gen with a CCFL display or a newer LED display?

edit: looked at your sig.

There is no "inverter" per say for the new LED display. its called a LED driver board. As far as i can tell, apple sends the LCD clamshell as one unit (inverter, LCD, LVDS cable, clamshell assembly).

Isn't it like a common knowledge that if you need a repair for the third time, apple is sorta obligated to give you another computer?

I had this issue aswell, went away after I stoped closing the lid to put the computer to sleep. Now I press cmd+option+eject. All is well
