Hi. Connect skybox using scartlead, or if you have HD use HDMI lead connection.. Select connection by using the AV (alternate video input) on your remote control--this will switch from freeview to sky. Happy viewing.

You might need to try to get the schematic and verify all the voltages--note in this kind of situation you need to measure each exactly at turn on in case one is going low or off quickly.The other thing you can do on the larger voltage lines (above say 12vdc) is with the set unplugged check resistance to ground on the chassis and look for any very low resistance readings--i.e. a dead short to ground.Other than this it becomes a game of guess, buy a board and try a board which always leaves the possible result of the panel causing this.Good hunting and if you have questions let me know.
