(This advice, of course, is applicable to MacBooks that have both discrete and built-in graphics cards.Check our /r/AppleHelp FAQ and basic troubleshooting guide before posting. discrete graphics because, per the developer FAQ, apparently when you uncheck that in the System Preferences Pane it actually forces the system onto the discrete card more so than the built-in graphics. Also, from what I have read, do not disable the automatic switching of the integrated vs. Try downloading and installing to monitor which graphics is in use when the problem occurs. This may help explain why it seems to work at one point but at the point where an app demands access to the discrete graphics card, the glitches surface because, allegedly, the connection to the board is in the early stages of failure. This is fairly typical, unfortunately, of what others were experiencing because the failure concerned the discrete (not integrated) graphics. With respect to MacBooks equipped with both discrete and integrated graphics it could be fine one minute (on integrated) and problematic the next (when using the discrete graphics card). But from the OP it sounds as if there are some problems showing up while externally connected, too, which would point to a graphics card issue.

It could be your LCD especially if you can run it to an external monitor without an issue. But my understanding is that video testing is not as comprehensive. AHT/AHD is good for memory, hard drive and checking that there is power to all the various parts of the logic board. It's my understanding that Apple Hardware Test is not as thorough as the diagnostic the Apple Store runs so you may want to schedule a Genius Bar appointment. They seem to have a lot of positive feedback. I can't say for certain if the connection of your graphics card to the board is at issue but if you try your luck with Apple and they won't cover it, you can research the service offered by bga_repairs. If the service is not covered and you don't want to be out the even bigger sum of money for a new logic board, there is a service by the seller ' bga_repairs' on Ebay where lead solder is used to re-do the connection of the video card to the board (which is supposedly the problem - the lead-free solder Apple used is better for the environment, worse for the longevity of the connection to the board). Apple's approach is to replace the entire board rather than to replace or re-solder just the video card. Even though Apple's repair program officially includes only the early 2013 Retina models, it can't hurt to call Apple and try your luck anyhow. Is this relevant to the issue addressed by apple below (although late 2013 macbook pro is not listed in the affected models)?ДЎ) In the external monitor there are no issues found, no snowflake effect or any other issue.Дў) Apple hardware test (AHT) when run, reports no issues.Д«ecause the graphics cards are soldered to the board, video issues aren't really fixable short of getting Apple (or an Apple-authorized) repair center involved in some way. The image also comes and goes dark every once in a while. After a while the image comes more normal, however there is slight 'snowflake' effect (little white snowflakes) all over the screen, very visible in a black or dark background less visible on more white colors. If I connect it to an external Monitor with HDMI it works. The Mac book however is booting properly. Since yesterday, whenever I power on my Mac book Pro the image comes distorted, coming and going, and later on not showing at all.
