Samsung UE32F4510 Red led blinking

[electrocuted]

This is a older set now i think around 2013 like lotas suggests check the capacitors for their capacitance and ESR and maybe also check the backlight leds do the backlights light up with the cable between the power supply and mainboard removed

This was my first question! When the cable was removed nothing lit up but I didn't know if this was normal. Now, could I turn on the power supply with the cable disconnected by shorting ps on/off pin to ground?

What did you think, after this manipulation your TV will work? Check electrolytic capacitors for their capacitance and ESR.

Has worked millions of times and is probably the first SIMPLE thing to try, so drop the smartass remarks.

Try simple first, unplug tv for 15 minutes, press and hold power button on tv not remote for 60 seconds, release and plug tv straight into wall outlet and try it.

Here is the table of pins for the connector power supply-main board

Ok, there you are:
Unfortunately my mobile is not that good in pictures... As you can see I tried to ground the power on signal but cannot see voltage than the +5v on power supply.

"if I remove the cable prom power supply to main board the backlight should light?" So do this and tell results, also post good focused pictures of each board and one of the whole back as to see how everything is connected.

No one has experience on this?

Hello, just got this TV not working. The led lights on standby but when trying to power on nothing happens and the led is blinking twice for 5 times. If I get this right, if I remove the cable prom power supply to main board the backlight should light?

Power supply is BN44-00604F, A5V is present but no switched B voltage. LED driver input is too low, 12V.
