Have problem with Q series 50inch tv switching on off every couple seconds
have changed main and power boards also on off switch all ribbon wires back lights working perfect
same problem but here is what I can not understand remove back replace touching nothing else tv working perfect run short time switch off leave on stand by or isolate from mains works perfectly run for few hours leave on standby or isolate from mains over night same problem
with so many tv causing this problem is it possible Samsung can set this to happen shortly after guarantee ends call me suspicious if you like I also can’t understand why no Tcon board fitted to this model I have not looked at other Samsung but seams all US model are fitted with t con board
