Hi
This set ,sometimes works for hours and sometimes switch off after few minutes.,
I think may be loose contacts,dry solder issue.
Any common issue with this chassis??
I could not able to find any dry solder in power supply.
Any help please.

Re: Samsung hp-t4264,

I would reflow the solder joints on all the heatsinked fets anyway. sounds exactly the same issue as the 50" version with almost identical PSU design.

On that one, fault was on the FETs on the long thin heatsink in the middle. Gently flexing the board at that location induced the TV to suddenly turn off. reflowed and fixed.

Worth a shot.
