is there any way to control TV brightness over HDMI CEC?

I built the TV into a frame and forgot to turn down the brightness...Any chance or would I have to unframe it in order to be able to use the remote?

Commands like echo 'volup' | cec-client -s -d 1 work fine, but is there any way to control the brightness? Maybe by transfering specific bytes?

Thanks in advance!

Have you tried: echo h | cec-client -s -d 1
