pins for turn on fsp123-3f01 power board

[spantor]

Hi.

Could someone tell me which pins to jumper to activate Power board fsp123-3f01. It is from a Grundig TV model 49 vle 6621 wp
Thanks un avance

yes-Pins 110vac and 50vac should be measured in alternating current.
If 5 volts do not appear on pin BL, then there is a problem on the motherboard.
to check the operation of the backlight inverter, connect pin 5v with pin BL via a resistor with a nominal value of about 1 kOhm

Some body can help me?

Hi, measure the voltage at STBY to start

Hi, measure the voltage at STBY to start

There is voltage on standby pin. Only in 5v pin. I don't know if it is normal or if there is some anomaly on this board

pin 5V =5v
pin STBY = how many ?

[spantor]

pin 5V =5v
pin STBY = how many ?

Apologies, I mean there is no voltage on STBY. I don't know if this situation is normal

[spantor]

?

When you turn on the TV with the remote control, how does the voltage on the pin STBY change?

standby has around 3v when I turn on the tv.The problem is that the standby leds make 2 flashes and then the TV turns off.When TV tries to turn on there is no any image and there is no back light, however there is 90v in the LED backlight + cable but there is no - in the LED backlight cable.I have my doubts about using this power board, for that reason I want to turn on this power board without the main board connected

Ok
How does the voltage at the pin BL change when you turn on the TV using the remote control?

There is -5.31voltage between pin bl and gnd when I turn on the TV. Then the voltage disappears definitively at the end of the cycle of the two flashes of the standby LED

This board have another board for leds

where do the pins DIM0,1,2 go?

[spantor]

where do the pins DIM0,1,2 go?

Dim 0.... 0v
Dim 1..... 0v
Dim 2.....1,6v.

In the last photo, the pin table CN2 is not completely visible.

The measurements I have made so far have only been in cn3

you need to check the serviceability of the backlight, apply a voltage of 200 volts with a current limit of 250 mA, red wire is positive, yellow is negative

Bl work

ok
how many volts when turning on the TV on S2001 between pin1 and pin4
