Turning on LEDS of SONY KOL-40HX750 BRAVIA TV without electronics

[satach]

I got TV without electronics board, only power supply board. How to make LEDS turn on ? I want to make LED light from TV. Here is photos of power supply board and pins of cable leading to signal board.

Here are photos of pwoer supply board and pin information of cable leading to electronics signal boards.

Hi,

I can´t find any LEDs in your photos. Can you mark them?

Which LEDs do you want to turn ON?
And why? for debugging purpose?
and how?

I don´t understand what you try to do.

I can't be certain but that looks more like a CCFL power supply than a LED one. The high voltage capacitors in the top right corner suggest its from an older TV, LED backlights are higher current but lower voltage.

I want to do this:

What else can you tell us to find your problem?

• Backlight Module​

  Dynamic Edge LED

how to modify the power module to run the illuminating LED matrices without electronics/signal module ?
I found some info that i need to put some signal on POWER_ON, BL_ON, DC_DIMMER, PWM DIMMER, but what signal ? 5V ? To all 4 pins ?

Connect resistor between power-on terminal and gnd, the power supply should work and output the voltage for driving the leds

Maybe resistor also for back light on terminal to gnd
