After Grahams post I thought that might be the safest option - I'm too young to die :-) Appears there is a 5V and a 3.3V regulator in here - I took the risk and used the 15V supply - so far so good. The screen appears to be working fine so far (3 minutes and counting ). Many thanks to Graham and David Dean

Silicon diode gets hot its resistance drops drawing more current and making more heat. -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
