Dell XPS 2710 - Flashing Red, Green, Blue on Start Up
Recently, my Dell XPS 2710 flashes red, green, blue on start up. Restarting the computer has no effect, it simply returns to cycling throgh the colors. It seems that the monitor is losing the video signal somehow, and switching to HDMI input. I should be able to get the signal back by using the third LED touch button located at the bottom right of my machine, but touching it has no effect.
Today, however, the machine went through the RGB cycling and fortunately stopped doing this after 30 minutes or so; I was then able to switch from HDMI to the computer using the first touch LED button, and I can now use the machine normally. I know from recent experience that the RGB flashing issue hasn't gone away, though.
I'd like to get the LED buttons working properly; currently only the first button for screen dimming works, the second button to adjust brightness never responds and the third is similarly unresponsive. Any ideas of how to sort this and get rid of the RGB flashing? I seen some related posts on the forum and followed some of their 'solutions' but my problem is still to be properly solved.
My video drivers are:
Intel(R) HD Graphics 4000 10.18.10.3958 (Date 30/09/2014)
NVIDIA GT 640M 9.18.13.3182 (Date 11/11/2013)
Thanks very much!

Hi Hokkaido,
Can you access the F12 utility partition and try running the Dell diagnostics on your graphics adapter? I think that's the most likely culprit.

Hello,
Thank you for the reply. I did the full ePSA diagnostics and the machine passed all the tests. Do you have any other suggestions? I want to get the LED screen buttons working again; then when the screen loses input I can fix it easily.
Thanks!

To get the LED touch buttons working, Dell support told me to shut down the machine, unplug the power cord, and press the start button for about 30 seconds. It didn't work, though.

Does anyone know how to stop the Dell LCD BIST (Built in Self-test)? Thanks!

This morning the PC started by going straight into the LCD BIST and cycled through the colors. My LED touch buttons aren't working, so I don't know how to stop the test. But after about an hour the color cycling ends, and I get the option to switch from HDMI to the LED screen using the touch buttons; at this point somehow the buttons work and the normal screen returns. Everything is fine except the buttons revert to their unresponsive state. I am still at the mercy then of the PC going into the BIST. This must somehow be connected to the DELLOSD software, but I have no idea how or what I can do to fix the problem. Does anyone have any suggestions? Thanks!
