I have four DLTs in the bedroom. The backlights for all four are set to follow a group which is set OFF as part of the Goodnight scene - this turns off the DLT backlights. This has worked perfectly for almost a year, but recently, two of the four DLTs have started to 'glow'. It is faint, but quite noticable. The glow seems to come from the bottom right corner of the DLT. The other two are still fine. Any ideas? :confused: Thanks, Lee.
