Large screen TV for Cobham Mill (Hersham KT12)

Cobham Mills is run as a charity, and we open every month, from April to October inclusive. It’s become so popular that we have to some of the talks on a screen outside (It’s small inside). But we are wondering if anyone has an old TV /Monitor we could have. Ideally over 32 inches screen size.
Thanks in advance to anyone that can help, can collect most days in the evening.
