Hi to all, I have a XPS 9560 with some faults, im working on it for fun, I have a "burned" zone I need to dremel but afterwards ill need a photo of the zone for rebuilding as far as I can, I have the schematics and the boardview but will like a photo, if some of you can get any so I see the traces will be cool.
It was some kind of lucky that the zone had not too much components, so I think I can deal with it.
Its under the zone where PC308 PC309 and PC337 is located, next to PU300
Thanks a lot for all and "pray" for me

Hi to all forum members,
Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.
Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor... -
Hello everyone,
I am new into this, sorry to post it here. I want to make this as a pet hobby project, as this mac is not urgent.
I have (Macbook Pro 13inch 2017mid) A1706 820-00923-A
My mac had liquid damage a long time ago, the connector from J8500 is damaged on pin 46 (PP5V_S0_ALSCAM_F), I guess the LCD/display panel is in short circuit, as I saw the connector from the LCD burned as well.
And the resistor L4004 is literally burned.
From what I see from the schematics, it does not affect any other rails, only the connection to the display... -
Hi,
Anybody has experience repair PSU burned out due to connect to EVGA molex/sata cables. I know the cable is not compatible (i got them mixed up), but I though i can connect it and use a PSU tested to find out which is the wrong sata/molex cables. As soo as I pluged in the powered molex cable to the PSU tester, the power supply short out, and will not turn on anymore. After the incident, the PSUs (both HX1200 and C850) try to power on and shut itself off immediately. The ATX PSU tester survice the short circult, still working perfectly. Anybody know if it's an easy fix or know which parts... -
