Ask HN: Tips for hacking a TV?

I've got a spare television lying around (specifically, a Samsung UN24H4500), and I thought it'd be fun to take a crack at seeing what I can do with it. The only hitch is that I've never really done any hardware hacking before, so I don't really know where to start!

Any tips and pointers would be much appreciated, in terms of common ways to search for and exploit vulnerabilities, or the exploitation of other televisions. Alternatively, if this is an absolute fool's errand, and the whole thing is locked down tighter than Fort Knox, a firm warning that this is not a good thing to dick around with over a weekend would also be appreciated.

A decade ago my LG plasma TV had a serial port for using it as digital signage (I think). If I spammed the serial port during boot I could interrupt U-Boot but they had disabled echoing out. I never figured out if I could do something useful or not.

Serial ports on tv are usually for screen control, as in turn on/off, change input, set volume... Like what you can do with the OSD and the remote
