Screens go blank randomly?

Taking a short break from the Waiting for Skylake MBP thread.

I'm running a mid 2010 13" MBP, with the 2.66 Core2 Duo (P8800 if memory serves), aftermarket 8GB of ram, and the blisteringly fast GeForce 320M iGPU.

I've recently bought a variety of ancillary equipment in anticipation for my Skylake MBP. Among those is a Dell U2414H, a splendid 1080p, 24" screen.

Since i bought this screen, which i connect via mini displayport, i've had both screens randomly go blank, not necessarily under any significant load. The blank color alternates between white, cyan, and magenta - but i have no idea why.

my computer tends to run hot (it really needs replacement) and i tend to watch a lot of video/ do some light gaming - but i run SMCfancontrol at max RPM when i do that, so i don't know why it happens. the "crashes" do not occur under high loads.

I tried googling for this, but have found nothing similar anywhere. has anyone encountered this before?

TIA!

To be honest it sounds like a slowly failing logic board.

That's what comes to mind as well. I hope it'll be able to keep on trucking until the new products are out ^^

A funny thing i noticed last time it happened, is that the sound keeps playing normally, as if nothing was wrong. So it seems like only the display component has a (quite serious) crash, but the rest of the system seems to function normally.

Like i stated, this only happened when plugged into the external monitor. When i run the laptop on its own, i never get these blanks.

Yeah, my guess is also the logic board. Would you replace the logic board on a 6 year old computer or put the money towards a newer computer?

Haha nah, i'm poised to buy a new MBP the moment the skylake versions drop :) replacing the logic board makes 0 sense.

Thanks for the replies!

I have a similar issue with my 2013 rMBP. My screen (only through the HDMI port and I tested with multiple monitors) randomly go black for a few seconds. It runs fine if I use the mini-displayport to HDMI adapter though. Have you tried a different port?
