None exist......thats why these TV's are not fun to deal
with on integration

For inputs you can select another input on the remote
then the one you want for good reliability...IE

for AV1
select analog HD then AV it will always come back to AV1

for AV2
Select analog HD then AV, AV..will goto AV 2

and so forth...select another input type then the right
type and if it is the 2nd input select it again

so HDMI 2 would be AV, HDMI, HDMI

analog 1 would be AV, analog HD

power just isnt there...Maybe a sensor if your using a
URC MSC400 or RTI RP-6
