This model Dynex DX-40L261A12 tv will not power on. The standby light comes on and the PSU makes a clicking noise when power cord is plugged in. But thats all.
Connection point with power cord plugged in on PSU.
I'm thinking PSU but like other inputs. Thanks in advance.

If i unplug XP1 on mainboard and jump 5v to stb is will click and you will hear the speakers come on then fade out.
