Zang, "power jack head must be plugged in specifically at an angle" sounds like you are running into a worn out jack and dry solder joints. Use [guide|3541|this teardown] to get to your circuit board and take a look at all the solder connections etc. The power jack is still available at places [http://console5.com/store/kits/power-supply-parts.html|like this] as well as many others. You can always check with digikey.com or Mouser.com and have them match you up. The static can be caused by the power jack, so start with that.
