I need help identifying this IC and, if possible, the value of the capacitors next to it. It is part of the HDMI circuit of an EVGA RTX 2060 GPU. It suffered a short circuit, leaving the graphics card without video and the TV without image.

Hello everyone !
I'm trying to repair the power supply of my Elipson W35 Bluetooth speaker. The problem is that the PWM circuit has no reference "it's a smd marked U4 on the pcb. The reference has been erased at the factory. Here are some photos of the circuit; could you please help me identify the circuit? Thank you, and have a great day
Important point: the resistor R108 marked R100 smd mount is a replacement and I'm note sur if it's the good value, it's relay the mosfet to the ground capacitor 450v
the mosfet is a :SVF12N65F

Hello,
I have this EVGA RTX 2080 Black Edition (Printed EVGA196) graphics card that works just fine when idling but quickly heats under a load.
I noticed fan speed always stays @ 0 rpm which is a problem. Under close graphics card examination, I found a burn spot near the FAN connector. Also, both pins 5 and 6 on the PCIx1 key are showing 13 ohms.
Voltage injections on either of these pins has revealed U628 heating up. I am including a photo of this component. It's some kind of a mosfet switch with markings "ELMAC" (letter "C" has underscore).... -
Hi. this is my father tensiometer. it that drives 6v and someone put a 12v charger on it.
i have a problem identifying this componet and circuit:
really apreciate if you guys could help me with this one, thanks in advante

Hi.
Could anyone have some hart and pity to help me identify this transistor? I believe this is a transistor but who knows... .
When it was in I had no ground on charging pins of actual earbuds. When unsoldered ground came back and now it is charging itself, it is charging earbuds as well and that did not happen before.
When I test it it don't look like transistor but like double diode leg 2(middle - possibly emitter) to 1 and 2 to 3 connected showing 0.8 volt drop, in reverse it is open circuit and across 1 to 2 both directions it is open circuit.
Is this a double... -
Hi friends of electronics
What you see in the video and pictures attached is the circuit for charging the batteries of a DC motor.
The problem is that this circuit cannot charge the batteries (3 1800mAH NiMH batteries) any more. When the circuit was OK, its green LEDs lit up one at a time to show that the batteries have charged more. But now that the circuit is flawed, LEDs light up as you see in the video and at the same time successive beeps are heard.
Please help me fix this circuit.
