I've replaced lid angle sensor, there is no change. I've noticed that while JP600 connected laptop does not boot/no display externally. -
No, as i'm testing it on brand-new screen and i don't want to waste a new angle sensor. I did check section next to LCD Connector PPVOUT_LUXE_XW 0.078v, is there a way and possibility to trigger screen enable signal or is too risky?Leave a comment:

I couldn't locate either of the section on the boardview, i checked by RD966 in between leg 1&2 - Short/OL 0.01Ohm.

I've replaced this resistor, still no backlight -
ppluxe_lx2 - 4.8v
LP800 - 0.250V
PPLIXE_LX2 - PPLIXE_LX1 0.250v
PPVOUT_LUXE_XW 0.250v
Checked everything around UP830 on diode mode everything in range of 0.200-0.800 but LUXE_ISL_R_P/N they're 0.0 as they lead to gnd i believe?Last edited by tommy97; 03-28-2025, 02:38 AM.Leave a comment:

Resolved - Problem was caused by IC on the other side of the board, needed re-flow.Leave a comment:

Apple MacBook Pro A2485 - No backlight
Hi everyone,
We're working on an [B]A2485 MacBook[/B] with [B]no backlight[/B] after liquid damage. The damage occurred near the [B]backlight IC (UP800)[/B]. We've checked all the nearby [B]resistors and capacitors[/B], and everything seems fine. We replaced [B]UP800 from a donor board[/B].
However, [B]UP830 was also liquid damaged[/B], and after cleaning, [B]resistor RK830 came off[/B]. Unfortunately, I can't find its value, and the schematic doesn't indicate it as a critical component.
Would anyone have insights or a way to confirm the RK830 value?

Macbook pro A2918 - trackpad does not work
Hi,
I'm working on an [B]A2918 (820-02757) MacBook[/B] that has suffered [B]liquid damage[/B]. We've replaced the [B]palm rest[/B] and cleaned the [B]motherboard[/B], but the [B]trackpad connector[/B] has [B]3-4 broken traces[/B] on the [B]top right side[/B].
We need [B]schematics[/B] or someone who can help identify where these traces lead. Any assistance would be greatly appreciated.
Thanks in advance!Hi,

Nintendo Switch Oled - Joy con charging
[B]Hi everyone,[/B]
I'm having an issue with a [B]Nintendo Switch OLED[/B] that suffered liquid damage. After a full cleanup and replacing the [B]Joy-Con rails and joysticks[/B], everything was working fine for about a week. However, now the [B]Joy-Cons won't charge or connect[/B] again.
I tested with a second set of Joy-Cons, and the issue persists. Measuring the voltage on the connector shows [B]3.7V instead of 5V[/B], which I believe should be the correct value.
Any insights or suggestions on what could be causing this?

Tried also with new audio jack, no difference, in output/input there is no available device. Also is jack needed to get output from the speakers?Leave a comment:

Apple MacBook A1707 No Audio/Sound
Hi,
I'm having an issue with an A1707 MacBook Pro—there's no audio output. Initially, the MacBook came in with a no-power problem, and I found a faulty U6400, which I've now replaced. The laptop now powers on, but there's still no sound.
I've also replaced U6300, but the problem persists.
Here are the current voltage readings:[LIST][*][B]PPV18_S0:[/B] 1.8V[*][B]R6402:[/B] 1V[*][B]R6405:[/B] 1V[*][B]R6403:[/B] 1V[*][B]AUD_SPKRAMP_RESET_L:[/B] 1.3V[*][B]PPBUS:[/B] 12.6V[/LIST]- Hi,

ASUS ROG G513R - works however bootlops
[B]Hi everyone,[/B]
We're experiencing an issue with an [B]ASUS ROG G513R[/B] laptop. It generally works perfectly fine, but occasionally, after being powered off for some time, it goes through [B]multiple boot cycles (showing the ROG logo around 5 times)[/B] before booting normally. Once it starts up, everything runs without any problems.
We've also noticed that this issue sometimes occurs when the [B]lid is closed[/B]. [B][B]Troubleshooting Done So Far:[/B][/B]
-Latest [B]BIOS[/B] installed
-Fresh [B]SSD & Windows installation[/B]
