Hi anyone got a schematic based around Haswell cpu which has the signal order or block diagram in it ?.

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... -
RJ45 Block Diagram / Schematic
RJ45 network connectors are most commonly found at either end of an Ethernet (wired internet) connection. At first glance, they appear similar to the familiar telephone plugs and jacks which connect landlines to walls or switchboards. However, RJ45 connectors are typically slightly larger.
The term RJ45 connector is widely used today to describe both male RJ45 plugs and female RJ45 sockets. The plugs, sometimes called modular connectors, are usually found on the end of Ethernet cables. The sockets or jacks are generally embedded in the device...10-31-2024, 04:18 AM -
Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.
I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...11-23-2023, 11:02 PM -
Hello everyone,
I'm turning to the Badcaps community to help me troubleshoot the radio Rx card from my (old) garage door opener. While I could just ditch that card and replace the whole system, I first would like to understand "why" it suddenly stopped working, because that's just how I am wired...!
Some basics: the receiver works on a 30.875 Mhz frequency. Yes, I'm aware this is not in use anymore in a looot of places. It does not use any rolling code, it's just a regular dip-switch code that you have to set up on both the receiver and transmitter. The receiver... -
hello guys,
first of all i'm not a qualified repair guy, i am a diy guy and as years pass by i have some experience on repairing eletronics, and i'm hoping someone can share their experience.
i have a marantz sr6012, some times it turns on and works normal, but after a while the sound cuts off or it starts getting distorted and then cuts off.
when this happens there is no audio no matter the source used, and the OSD shows unknow audio signal from the source.
i was reading very carefuly the service manual and it is all pointing for...
