I've been playing around with RS-232 control on a LG 42LE8500 tv and it works like a charm. All mentioned remote codes and commands work as described by the manual.
However, I got curious as to whether there were some undocumented codes which would allow some more control... Instead of just reading values from the tv I accidentally wrote values using the following commands (device id=1):
ab 1 01\r ac 1 01\r af 1 01\r
(_don't_ do this!!)
The commands ab, ac and af are undocumented in the manual but affect things like bluetooth functionality, availability of particular inputs (when selecting a source) and probably more..
By trial and error I was able to get most functionality back to normal, but I'm looking for a way to _really_ reset the tv to factory defaults. The menu option "factory reset" doesn't affect mentioned settings and unplugging from mains / firmware update didn't help either.
Does anybody know a way to restore these settings (if needed via RS-232)?
Or could somebody provide me with the initial values for ab,ac,af commands (on LG 42LE8500 or similar)?
They can be found by executing (again device id=1):
ab 1 FF\r ac 1 FF\r af 1 FF\r
responses are of the form:
b 00 OKe61ex
above case is the response for the ab command and shows a current value of e61e (16bit value)
Any help is appreciated, regards
Martin
