Broken - Samsung TV 32 inch (Lambeth SE11)

It can probably be fixed quite easily but someone who knows how, and used or sold for a few quid.
There is no remote, lost that a few years back.
It was working really well, used it as a giant laptop monitor. But suddenly it stopped working.

I will leave it on here for a week or two in case someone who knows about TVs wants it.
