Hi, I have this system which has worked fine for a while, however I am now having a problem. This system has a main remote control sensor that if is not plugged in renders the system usless as you cannot use and functions which are all done via remote control. This is where i am having my problem whenever i plug this part in it shorts the hole system and will not let me turn it on. If I un plug this I am able to turn the system on fine but cant do anything with it. Is this a protection circuit problem???? Thanks for any help.
