Re: Lenovo Thinkpad T560

"mon2" Thank you very much for the infomation.

Re: Lenovo Thinkpad T560

Both Digikey and Mouser are showing stock of this component. That is very rare, given the current shortage in the semiconductor industry. I would grab a few spares from either supplier. I think that DK will be cheaper at $8 shipping fee vs. $20 with Mouser.

Re: Lenovo Thinkpad T560



This is a new matrix purchased. a new one with a defect will be the complaint procedure, when the matrix was lying flat on the desk it worked properly, only mounting it in the screen wing revealed the defect, I had a problem finding the defect.
I was misled into thinking that other lcd panels had been tested and that was definitely a motherboard bug.
This is an error of the LCD panel. proper interview, knowledge of the history of the device and I would not waste any time
I hope I wrote correctly and understandably

Re: Lenovo Thinkpad T560

lcd panel = NV156FHM-N42 V8.1 if I'm right, light control = signal pwm, LED power in the panel is all the time (19V or battery), enable panel and PWM signal (lighting power) they are also always there, so I'm looking for an error connecting the panel to the board, a colleague who gave me the laptop for repair, he said that the panel was replaced with a new one but it did not help, no one checked the cable, I measured the cable but it was removed and bent differently
the panel is also not lit in bios, without any additional drivers

Re: Lenovo Thinkpad T560

If you can control the brightness under Linux than the hardware (logic board) is working fine.

Most likely a missing device driver on Windows for this laptop. Check the Lenovo website for the full Windows driver package.

Pin 24 & 25 on the LCD connector = USB. Perhaps some USB driver is required to support the brightness control of the display ?

Re: Lenovo Thinkpad T560

The situation returned, no backlighting, voltage on pin 32 = 3V ok, the same with other signals, you can see the image on the screen illuminated by the flashlight. I will look for a new lcd cable, but first tomorrow I will check the cable transitions but plugged into the connectors.

thank you colleagues SMDFlea and pn2, the topic will describe when I detect something
