Hi All,
I obtained a schematic diagram for the above mixer but I am wondering if a block diagram exists as I am trying to fix a problem in the protection circuit which I find a little confusing using a circuit diagram only. In the good old days the workshop manuals always had a block diagram with a circuit discription. Very useful for fault finding.
The protection light is perminently on. The right sode has a -80DC on the feed to the speaker, hence the protection led on. I have removed all the O/P transistors which checked out OK. I tested all other transistors in circuit which seem... -
Hello everyone,
I'm encountering a frustrating issue with my Corsair SFX 450 power supply. After an undefined period of operation, my PC will either suddenly restart or, in some cases, it won't start at all until I disconnect the power cable and reconnect it. This erratic behavior occurs intermittently, making it difficult to pinpoint the exact conditions under which it happens.
For context, I have tested the PSU using an electronic load at 150W, and under those controlled conditions, it functions flawlessly. This leads me to... -
hello everyone, I'm looking for the wiring diagram of this led monitor.
the model is DHI-LM19-L200, but I think that any other diagram of a DAHUA monitor could be equivalent.
I really hope that among you someone can help me to repair this monitor, the screen is black, it doesn't seem like a backlight problem.
I see the presence of 12 volts, 5 volts, but without a diagram the repair is very difficult.
thanks to those who will answer12-10-2024, 04:37 PM -
Hi, i have a hotair station LK852D-2 , and the problem is about the air flow is little and hardly to getout any air flow from it, i unfurtanitly replaced the potinmeter 500k ohm with new one, but it never solved the problem, and then i unsoldered from the board as you can see in the attached photo, and that make Some parts of the circuit diagram been damaged, and I need someone who has the same circuit diagram to provide me same photo of the diagram, especially the place where the 500 kΩ potentiometer switch is located( the place of 500k ohm potentiometer is indicated it with red arrow in the...
