I may have made a mistake and got a 32" Q50A as I wanted to hang it on the wall, but the screws I had did not fit so called Samsung help line who unhelpfully told me the wrong size. So now I don't know the right screws to order and after 4 weeks still don't have this tv up and working. If anyone can help me please with something in the UK.
Just in case others are reading this - the correct mounting bolts on this TV are actually M4. Depth of mounting holes is given as 19mm to 22mm (you can find this information in the 'quick set-up guide'. I used M4 20mm bolts and these worked fine.
I have tried all M4 bolts, 4mm screws and even tried imperial equivalent as last resort…nothing fits. M6 is too large as that’s what everyone states must be used for 30-40” mounting. M4 come as standard .70 pitch not 1.25. M6 are 1.25 pitch but as said previously don’t fit
