hes going to find it tough tracking down EXACT codes for a 14 year old unit. I doubt it has discrete power codes. I'd sugest, as previously mentions, start with a blank templatye and load 30 codesets into the remote. Then test for proper functioning. Knowing that discrete on and off probably arent available, find work arounds. you mentions an input turns it on. Then discrete on could be one of those inputs. Power off woud be one of those inputs - delay - power. Im sure almost any of the power codes will work.

I'd suggest testing codes for ALL devices first. Then build a design for your system. AFTER and ONLY AFTER all indivudal codes are found and known to work then build macros.

THEN and ONLY THEN, attempt to work with RF.

If you dont follow some structure you will be quickly frustrated.

to recap.
Find codes needed for all desired functions. Verify proper operation of codes
Build template in logical fashion
Build macros and test delays, logic, etc
Work on RF use.
Hide all pages and codes that everyday users dont need to have access to.

Need a file for example? Send me an email.

I'd also consider replacing that Sony unit for something made in this millenium.
