Upside down tv (Downhead Park MK15)

Odd one. We have a 32" TV which works with a firestick. I bought a new pcb when it went pop and installed it. Screen picture became upside down but it works fine. We tried a few things to put picture up right way. No use. We thought of using it suspended from ceiling but actually it would work on one of those flexible arms. I realise it's a long shot but wd happily give it. We used it upside down on my shelf using blue tack to stop it sliding off, then my friend gave us a replacement.
