what is this electronic component with 20 pin
-
Hello. I am working on a circuit board that is part of a motorized HDTV lift. The circuit board belongs to the controller component that tells the motor to either raise or lower the HDTV height.
The controller started sparking when the 29V power supply was attached and the green light on the power supply would go out as soon as it was plugged into the controller board. This indicated a shorted component and I was able to identify which component it is that is causing the short. When I remove this component, the short is cleared.
The problem is finding a replacement component.... -
Hello, I post there because I guess this component is well know in mobiles devices. In the DSLR, Nikon D750 there is 3D virtual horizon, so there is component : gyroscope ? I guess for that.
This component is probably dead, because the virtual horizon don’t move anymore.
I can’t find this component, I dont know what it looks like ? (I have 2 other dead boards so I have repair parts).
I tryed to find on the web, that could be a little qfn, same metal box as oscillator ???
I found nothing on the board except one weird stuff (see picture ; black component)…
But I have...10-15-2025, 02:32 PM -
hello
today i have laptop Acer aspire V5-591 DA0ZRYMB8G0 REV: G MODEL: ZRY
the problem of this notbook is powering on but black screen, when i verifing the motherboard i found TWO electronic component not found! AS PICTURES BELOW please help
,thanks ADVANCED.... -
Hi Everyone!
The SMD code is AB5IB. It's a SOT-23 component (or similar).
I tried to decode this component on every site I could find (SMD Code Book, etc.) with no success.
Does anybody know what this component is? I have 2 of them on the board, and both give the same readings. I used DMM, as well as PEAK Atlas DCA75 Pro Advanced Semiconductor Component Analyser.
Atlas says that NO COMPONENT IS DETECTED (both of them). Usually, it can detect ALL types of transistors, including Darlingtons, MOSFET, BJT, JFET, etc., Volt Regs, Diodes, etc. If... -
When I was replacing the opposite side of the PCB, I did not remove the plastic tape on the AP so when it shrinks from heat, it knocked off some component and it is no where to be found.
One of the component in the AP is missing. It is this weird long component. I think it is a capacitor but I am not sure.
Anyone know what component is it and what typical value it is on the AP?
The laptop that I was working on is a MacBook Air 2.
