Sometimes I can see a service manual there. But in your case, can't find that model.
One of the switches on the switch unit gives all of the symtoms of being stuck. I dont use the manual switches so I want to disconnect the offending one and control the TV from the remote. The loom between the switch unit and the mother board has 9 coulored wires in it - if I diconnect the plug ( all nine wires ) I loose the remote as well. which color wires are for which function?
