I am close to the end of a job and need to sort out a problem with two sharp LCDs that are being controlled via RS232. One is a current model 52" Aqus LC-52D85X, the second is an older 32" model LC-32GA4X.

I'm using a RTI system for control, XP-8, T1 for the 52" and a RK2 for the 32". I have sent the Disable Power Save Off String, RSPW0001\r to each and have confirmed in the menu that the Ecology Setting is Off.

Both units Power On and Off correctly, BUT, if powered off (Standby) for more than about ten minutes, thay won't Power back up out of Standby via RS232.
As a work around, I have Set the T1 Source selection buttons to Stand Alone mode and am sending a Discrete Power On command, the down side to this is that it powers up on the last Input that the screen was on when powered down, instead of selecting the new input, which means a second push of the correct Input Button is required.

May have to live with that one! Any suggestions?
