by aaronkatriniHi all,
Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.
Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...Today, 03:15 PM -
by karloxGood morning, can someone share with me a copy of a working BIOS for this computer? I downloaded them from the hp page, but it is not working for me, I attach a copy of the backup of this card. The worst thing is that it's working for me, I have a suspicion that I'll have to program the EC, the motherboard license plate is DA0P9MB26A0 REV. A

by r2digitalI have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...2 PhotosToday, 03:50 PM

Hi, I need help to identify the component with marking "9003 KAUCHB".
A bit of background...
I have an induction hotplate UNOLD Elegance Typ no. 58105 (with board CHK-A1.42S) which has a blown resistor.
I have also located the problem in the SOT23-6 component with the marking "9003 KAUCHB"; the pin 5 was disconnected from the IGBT emitter (ground) due to the high temperature and this caused the IGBT to be permanently ON.
I replaced the resistor and resoldered pin 5 of the SOT23-6 component to the IGBT, the hotplate worked for about a month and...1 PhotoYesterday, 12:55 PM -
by BholuHello friends, I have MTC 58' TV which has stand by position. I thought the software was corrupt. I have downloaded the software from the internet but the data is not matching. The format window is opening from the TV software but none of the buttons on the remote or TV are working. Why? Can I edit this software with a hex editor? Is there any guide to edit this? Or does anyone have access to this software? Thank you very much for your help.

by crosswindsHello,
So, pulled a motherboard out from storage, was working when put away, wont post when I took it out of storage today.
Since it was working, and it looks to be essentially time that killed it I figured its a good idea to replace the caps before digging further.
Looks to be only good quality caps on this board, so might not be the issue. But it is closing in on 20 years now so, wont hurt i guess
Its a ASUS P5VDZ-MX board.
I would really appreciate some assistance on what the best replacement caps would be for these:

by norbiszokeHello,
We have this set here in our shop that is not ginving sign of life besides red light that is blinking one time after pressing the button and nothing more... After detaching the mainboard from the PSU (this set has separate board thank god?! or not...) the backlight comes on. After reattaching nothing besides red light.... Can anyone from the forum help me here? Thank you in advance. Here's a link with images of the mainboard and the memory IC's that are on it.

by Keshenatech1Does anyone have a schematic or parts list for a ZWS150BAF-12 12V power supply? I have a dead one and I've determined the surface mount diode on the back side of the board that connects from the center leg of Q3 to the + side of the 420V 60uf capacitors has a 3.5 ohm short. I'm not having much luck trying to identify the diode as the part number is not very legible. In the attached picture, it's the black rectangular diode in the center. There are some numbers on it but I can't even tell if it's right side up or upside down. The picture is from a 2nd good working unit which is more legible...Today, 08:58 AM

by edugimenoHi everyone!
I have this board that suddenly stopped supplying power to an output that drives an interchanger cleaner motor.
I checked while the board was in place with all wires attached and there's no AC voltage on the corresponding plug X5
This X5 is driven by fuse F8 (tested OK) which comes from the second orange relay
To make sure there are no charcoaled contacts inside the relay, I got a 24VDC power supply and got it ready to manually power up the coil side of these relays.
I respected the polarity, positive to cathode of protecting diode
So provided all...Today, 01:15 PM -
