How can I keep this TV power board ON?

[hanswr]

Recently I broke the screen of a TV and I would like to re-use it as a LED lamp.

The only problem is that I don't know how to make the power board to provide the voltages without the main board and power button connected.

Would you help me identify the correct pins that I need to short (and how) to make this TV power board work as if the TV was on?

Thank you very much in advanced.

You should be able to turn the power supply on using 1k resistors. Connect one resistor between 12V and stb and another between +12V and SW (this turns on the main power supply)
connect another resistor between 12V and enable (pin13? of XP805) This should turn on the backlight, if it does not, connect an another resistor between 12V and PWM (pin14 of XP805)

Same board on this thread? Should stay on the same thread.

Thank you very much. I will try that.

It is the same board yes. That post did not get any more responses maybe because it was no longer related to troubleshooting a faulty TV. My first mistake was to reopen that thread asking this question about the power board.

I apologize. You can delete either one.
