I have a similar problem, what I would like to know (since my power
supply isn't operational) what are the voltages on the power supply out
pins? I believe that from left to right the colors are:
blue : black : black : red : red : yellow
I'd appreciate any help you can offer.

Possible there is a fault in the feed voltage to the display as the power supply can be pulsating. Please check the voltage on the display panel using a analogue multimeter and if it will shows a drifting signal the power supply unit must be checked . test voltage on the board to confirm if any capacitor has gone weak. If there is no voltage shift then the display driver IC is faulty.
I had a similar issue with my ASUS. Try finding a program on your computer other than the Control Panel that controls the trackpad. For instance mine is Elan Smart-Pad. Usually working with some of the configurations in the program reinitialize the trackpad. If that doesn't work make sure that it isn't turned of due to keyboard interference (hitting a button that turns the trackpad off). Hopefully that isn't the case though.
Ok, my Elan Via!dj unit was doing the exact same thing. This is how you fix it. Take an aluminum baseball bat and in an over-the-head, ax swinging, motion, strike the unit from the top 4 to 6 times. Dispose of unit in dumpster. Fixed. - John Wilcox of San Diego California
Power off the unit. Under the right corner of the drive tray is a small hole (see pic). Find a paper clip that fits the hole. Straighten the paper clip and slowly push it in the hole. The drive tray gears will begin turning forcing the tray open. Gently pull tray all the way out. Power unit back up and see if it starts to respond again.
I don't know if it will completely fix the issue for sure but it is worth a try. I have had good results using this method if the drive is not truly broken.
I have just repaired this same fault, check voltage with test meter on the main board from the power supply it is labeled with 0v -12 +12 and 5v (two of these) if the voltages are either low or rather high (usually within 5%) replace all the electrolytic capacitors on the power supply PCB ,( it's the small one in the corner next to mains inlet.) This should fix it for about £10.00. Hope this helps
You will need to have the device dissasembled and checked for a loose connector to the mainboard. Those 2 components are linked to the mainboard via a ribbon like cable that may not be making a perfect electrical contact. It'a a cheap repair, you don't have to worry, other than that if the device is still in warranty it will be made for free.
