Removed the board and checked, The PPBUS_G3H has 2 ohms resistance with respect to ground. But couldn't understand who is causing the short. And the current consumption of the board is 20V and approximately 40mA (May is not accurate)
I have also found this extension cable on the web, Does anyone tried before me this cable for modifying an existing broken cable?

Hi ,
I have two laptops with display flex gate issues, It behaves weirdly in particular lid angles. I have found some youtube videos people are extending the cable using additional flex cable. I was just wondering if anyone knows where I can buy this cable for extension?
It must be 820-00239-09,
But I don't see a keyboard backlight, But the keyboard is working. The touch bar is not working at all, I mean no response no backlight.
Hi,
I have replaced the display panel, Not the full display assembly but just the panel alone, I don't know the reason. The board boots perfectly, It passes the diagnostic test without any error. But the touch panel is not glowing.
Some history:- While removing the display I have disturbed...
I have made a connection from the xw7720 n via to D7701cathode.
When I connect the screen I get 0V at o/p, Still, the display image is there.
But Q7706 is not turning ON. Q7706 gate has 8.2V.
When I check Q7707 Gate - the 5th pin is 0V and the 2nd pin is 3.3V.
I had 8.5V at the boost circuit output, I have changed the backlight driver and wired the missing feedback line. When I connect the feedback wire input fuse is failing, Not sure why. I don't see any short at output
It is not happening always, it's happening when I keep it long time in cupboard. Something related to temperature I think. Will display performance impact depends on temperature? Yesterday whole night laptop was outside and it was ON. Today I don't see this flickering anymore
Please find the attached video link, I don't know why it is flickering intermediately. Did anybody faced this issue ?
I have checked with external screen but I can't see flickering in the external monitor but the internal one is flickering...
