Hi I have a problem with this notebook, the computer works smoothly but only with the hdmi output, I don't see anything on the main monitor, it stopped working at any moment, it could be the display, the fhd cable or something else ?

Check the internal Display Connector for 19V and
3.3V being present while internal Display ist connected and Lid is Opened.

It Would be nice to have a HQ Pic of the connector and the surrounding components

Refer to any schematic with 40 pin connector and check whether you have +19V/LCD_VDD/Backlit_ON etc signals on the connector.

thanks for the reply, i can't find any lvds schematic showing 19v, i only see 3.3

Re: hp pavilion 15-cs006nl

Usually pin 27 & 28 are the two pins for INVPWR_B+(meaning 19V) on an edp connector.You can take LA-C701P schematic for reference as it too has 40pin Edp connector.

Re: hp pavilion 15-cs006nl

if pin 1 is the first from the right the one where there is a white dot, pins 27 and 28 give them to me as ground

Re: hp pavilion 15-cs006nl

this scheme is perhaps more appropriate

Re: hp pavilion 15-cs006nl

I confirm what was stated before, the right connector is this in the picture and I have both 19 volts on pin 1 and 3.3 volts on pin 40

Ok, if this is the right connector then check VADJ and BLON pins for voltage. Check carefully is it no display or dimm display on internal screen.

what voltage should i have in these two pins?

[mcplslg123]

Re: hp pavilion 15-cs006nl

3V approx.

Re: hp pavilion 15-cs006nl

3V approx.

this measurement is difficult to do, the pins are too close I am afraid of shorting something, also those two pins seem not to be connected with any nearby point to make the measurement more safely

Re: hp pavilion 15-cs006nl

Yes, there is risk of damage while measuring. You need needle sharp probes to do this.

Re: hp pavilion 15-cs006nl

I close the thread as solved, the problem was the display, thanks to all
