Hi
Done a search on this and found nothing....probably exactly as you did!
Do you have the TV? It's likely to be a VESA standard as it's a generic re-badged TV. 32" tend to be VESA standard but sometimes go up to 400 x 200 which wouldn't fit on a standard VESA bracket.
I see there's someone else on the forum with one of these, hopefully they can help further.
Regards
Graham
