Samsung le40a656a1f reaaaaaly slow poer up

[electrocuted]

Still no sign of life, plugged it cold and nothing on screen. You are right about the consumption of tcon, when disconnected and reconnected to main board the power supply drops for an instance (fan slows down and backlight turns off) then comes back on. The tcon chips remain cold during operation!

balls are way much gone, reballing is a method, but is it worthing so much time?

I guess not, but it may be a voltage converter problem on the tcon. I repaired some tvs in the meantime and it's the only one left in the corner...

Sorry, what do you mean by 4 tensions? My english is worse than the tv condition...
