Just something to block the IR-receiver in the small TV. That suffices to have it not 'listen' to the remote. I assume it still has a physical on-off button, and that's the essential part in a digital picture frame.

Den has 42" TV and just added 24" TV, planning to use the new one as a digital picture frame only, streaming photos from network computer. Problem is, can't turn either TV on or off without the other one doing it too. There must be a workaround, but I haven't been able to find it.
