Hello,

I am having similar problems with my TV, it has the same PSU and motherboard as yours . What turned out to be the problem in your case? I suspect it was the motherboard? In my case, the LED flashes only one time when the power cord is put in the outlet and it doesn't flash anymore. I'll check the PSU shortly with my multimeter, I'm curious if I'll get your results
