We had a phone call from a lady who has a fault with there system in there townhouse. The contractor who installed the system has since closed down and isn't operating anymore. I have asked around but there is no contractor in Town who is up to date with the product or programming. I have tired calling a number I was given for a HPM Icontrol engineer But he hasn't returned my calls. can't seem to find user manuals or installation manuals on the Internet. If anyone can offer any advice or info it would be greatly appreciated. The fault is as follows. Touch screen has the following message. "Welcome Home Touch Any Where to Begin" if you press the touch screen it will beep but nothing happens. I have checked the power supply voltage and it is 12dc (no load) and with the screen plugged in it is down to 9vdc. Is it a power supply fault? Is there anyway to perform any tests to diagnose the fault?
