Hi everyone,
I recently bought a used PS4 and discovered that the power button is broken. Upon closer inspection, I found that the traces for the power button on the PCB are damaged and torn.
Does anyone know where these traces lead or have any advice on how to repair them?
Thanks in advance for your help!...Yesterday, 05:01 AM -

Hello,
I have a A1706 with 820-00923-A board. The laptop came in with non-working keyboard. I bought a new top-cover with keyboard and transfered everything to the new topcover.
Since then the macbook will not charge or power-up. Before replacing top cover, I started the macbook to test, and it worked fine apart from keyboard. Then shut it down and did replacement.
This is what I measure so far:
Resistance from F7000 to ground is 123 Ohm on pin 1 and 2
PPBUS_G3H = 0,79v
PPBUS_HS_CPU = 0,79v
PPBUS_HS_OTH5V = 0,79v

Hi
That laptop wont charge I dont know if the charger is genuine.
To investigate further does anyone know about
how the id pin works for this model, is it a pullup to plus or a analog voltage divider or a
complete digital exchange.

GPU: EVGA RTX2070 Black Edition XC Gaming
A few weeks ago i noticed a burning electronics smell in my room, after a bit of confusion i realized that the RGB LED light of my GPU was out. Weird.
I didn't think much of it until i tried to look at the power usage in HWinfo, i then noticed that the entry "GPU Power (Total)" was gone entirely, it would also not boost above 1410Mhz.
Looking further i noticed that "Performance Limit - Utilization" was always at "Yes". The card did perform mostly...Today, 08:34 AM -
Hi group,
I am looking for a replacement for Nichicon PLV1J220MCL1TD (22uF, 63V, Conductive Poymer Aluminum Solid Electrolytic, 8x9 but we can go up to 8x11).
While searching, I found some APAQ and ELITE replacements that would fit on our products (APAQ ARHA series and ELITE UGT and UPD series).
How good are these brand/series and what other alternative would you recommend? I've searched the big name already and didn't find an equivalent.
Thanks!Today, 08:08 AM

Hello
I am repairing the A2780 (M2Pro 16").
There is no schematics and board view of A2708 yet, so I am referring 820-02100 (A2485).
Stuck 5.2V, 0.02A
'PP3V8_AON' short on diode mode and no voltage.
'PP3V8_AON_MPMU' short on diode mode.
'PPBUS_AON' looks fine. 12.3V
'PPVIN_P3V8AON' looks fine(not short on diode mode), 12.3V
I tried to remove the U5700, Q5800, Q5820, Q5840 and PP3V8 aond still stuck.
It seems to be a problem in the process of moving from 'PPBUS_AON' to 'PP3V8_AON'.
Even if I check with thermal...Today, 06:50 AM -
Good day,
I have a motherboard from a Lenovo legion 5 laptop. The previous service was unable to repair it. So I started the repair myself. The motherboard wouldn't turn on at all. The problem was in the mosfet in the PU101 which starts the power supply and in the PQ8203. And in the burnt Lenovo IT8227E chip and also in a short circuit in the power supply. I fixed and replaced everything. I have the same parts board. Now the board turns on and the battery is charging, the power button lights up green. But I am not getting the image. And the board turns itself off in approx. 25-30...Today, 04:49 AM -

I need to find a replacement for this diode on one of the six gate drivers of a full-bridge IGBT inverter for a servo motor. It has S3 on the package. How can I find out for sure the right diode that I need. I believe it is schottky because it has 0.2V drop across.
The anode is on pin Ve and cathode on pin DESAT on 316J gate driver IC. Also would be nice if anyone had an idea of the purpose it is serving as it is not included in the suggested schematic of the 316J datasheet.
