I have a L650 with no display. The lvds connector was pushed in reversed and created damage that way.
U6200 was blown and after I replaced it all the voltage, 3V and 5V is back but stil no display. I checked the rest of the voltages 1,5;1,8 and they are there. also VBatt 19,46V. I'm stuck now.
Can somebody guide me in the right direction?
U6200
1- entrip1 = 1,31V
2- tonsel = 3,35V
6- entrip2 = 1,31V
8- Vreg3 = 3,35V
16- Vin = 19,47V
17- Vreg5 = 5,10V
U3000
1- LCM_BKLTEN = 0V
2- EC_BKLTEN = 3,35V
3- = gnd
4- = 0V
CN3000 jlvds1
pin 2,3 = 0V
pin 4 = 3,35V
pin 5 = 3,35V
pin 6 = 3,35V
pin 7 till 19 = 0V
pin 20 = 0V
pin 23 = 5,11V
pin 24 = 5,11V
pin 25 = 19,5V
pin 26 = 3,35V
pin 27 = 1,5V
pin 28,29,30 = 0V
That is what I have been measuring up till now.
I do not know where to go from here.
thanks
