Re: lenovo v580 only backlight on display
as i said the led screen and lvds cable is replaced but still same problem
the pch manage hdmi lvds and crt but the part that manage the crt and hdmi is diffrent than lvds....
if i have not backlight on screen maybe the resistors behind the lvds socket was dead but the problem is lights on but no data signal on screen

i have display on hdmi port but the laptop screen have only backlight on and no data

Re: Lenovo Y50-70 Completely dead, no lights at all.
took of the ram and test again
first check the 3.3 voltage on power switch and i/o and bios ic
if you had that voltage try programming i/o and bios because its very common on this model
but if you have not the voltage then you should start testing the board on schematicLeave a comment:

Re: asus x450 kb9018 program
i did all the wiring and check the connection between i/o and programmer with mulitmeter and its all correct but still rt809f cant detect!
2 problems here
1.in the software there is no kb9018 so should choose 9012 or 9010
when i connect the ks03 to gnd the 3.3v(its actually 4v) around i/o that i connected to programmer is gone! so i pull of the adapter and connect the 3.3v directly to power supply
programmer cant detect when i choose 9012 or 9010 but when i choose auto isp the error is " pin 3.7 is...Last edited by s.m.hosein; 06-12-2017, 03:10 AM.Leave a comment:

Re: asus x450 kb9018 program
i followed kb9012 pin datasheet on keyboard connector and wire them to programmer no result but what i understand later is when is connect ks03 to gnd the 3.3 voltage around kb9018 gone ! when i disconnect ks03 gnd 3.3 is back!Leave a comment:
