Hi Bruce, and thanks,
RCU has the button you mention, so pressed it - totally ignored.
RCU is a new one as thought the old one duff - Ah well, thanks again - Chris.
Surprisingly set came on this morning on it's one channel - great picture and sound. Other thing is that the OSG is stuck on, and can't be turned off - Have an Eeprom feeling.
Think I need a bin or a dump - Plasma always give me those basic excretion based options.
