Re: need help quanta r33 rev 3.0
It doesn`t have to be shorted, take it off and see if voltage comes up, if it does make sure to put a new cap on there ,don`t leave it off.Comment

Re: need help quanta r33 rev 3.0
PU8 pin 16 (VIN) may be shorted to ground. Or there is a break in the line between PR116 and PU8. Or either PR116 or PU8 is not soldered properly. Also make sure PR116 is indeed 10 ohms.OpenBoardView — https://github.com/OpenBoardView/OpenBoardViewComment

Hello , for some time I was studying Quanta U9x/8x schematics and the option to use both type of screen (LVDS 40 pin / eDP 30 pin).
In some cases to use LVDS screen PCB use converter IC RTD2132/6
Now I found an HP 15 F series U99 mainboard with RTD chip not populated and LVDS 40 pin lcd touch screen
at the same time I have another HP 15 N series with Quanta U92 mainboard and RTD2136 with eDP 30 pin lcd screen (no touch).
Maybe someone more experienced in the subject can clarify if is posible to change type of screen used with some resistors / bios options change.

Hello, everyone!
I need schematics of this board:
Model: Dell Inspiron 14z-N411z
Board No: DA0R05MB8D2
REV: D
Quanta project: R05
I have already seen the file ''quanta R02_UMA.pdf'' in this thread:
https://www.badcaps.net/forum/showth...dell+14z-n411z
but it is differ from R05_UMA and it can't help me in my case.
The main problem of the laptop is as follows:
LED backlight is absent in the screen and appropriate 36's contact of the LVDS 40pin 1ch connector is shorted... -
I have an HP gaming 15-0013dx laptop , motherboard quanta G3HA with AMD Ryzen 5 cpu and Nvidia discrete grsphics card. The laptop turns on and u can see the screen polarizing on and off in a loop but no video signal. All voltages are ok measured and stable (I checked all with oscilloscope). This schematics don't have power sequence but I'm using a similar sequence from another laptop with AMD CPU and I get all to the point CPU must release apu_pwrok and apu_rst#, this signal comes valid only for the period of time the screen is polarized and they disappear and same loop behaviour (active/inactive).... -
