        How not to Damage an Oscilloscope
        by Tarot Superstars
        Hello.
        I have jut got my first analogue oscilloscope. An Isotech 620 20MHz.

        I want to learn how not to damage it, and I found instructions on the internet obscure.
        They talk about ground, earth, floating ground, this, that....
        But they don't actually say anything anything useful so far.

        I want to know:
        Don't connect exactly this to exactly there or it blows up.

        For example, I am tracing a signal from a function generator in an audio amp, or testing for voltages in different parts of a circuit.
        I want to know what not to connect...

        Sony STR-DE445 did I get a faulty IC?
        by goodpsusearch
        Hello, I got this AVR for cheap and tried to fix it as a fun and learning project.

        First the audio video receiver would turn on but had no sound at all, but no "PROTECT" message.

        So, I opened the metal case and noticed some marks showing that some liquid has been spilled on the amp. Those water marks were found on the main board and the digital board.

        I disassembled everything, then checked every single cap on every board of the amp and recapped when needed.

        Also fixed A LOT of cold solder joints and also done some modifications,...

        Recommended resource for learning/using this EZ Digital Oscilloscope DS-1100
        by creationtribe
        Recently my father-in-law sent my wife and I out to Arkansas from SLC, Utah to pick up a van. Weird, but true. My father-in-law owns an auto repair shop and found this beefed-out van with a wheelchair lift (I guess those are really expensive).

        The woman we picked it up from was getting rid of her father's estate after he passed.

        While we were there - she had opened his garage to give us the extra seat for the van - I saw an oscilloscope sitting in the corner. I guess the guy was an engineer. One of the really really smart ones that worked on projects 12 levels above...

        Medion Erazer beast x25 freezes and resets only at low CPU usage
        by kuba2102
        Medion Erazer beast x25 62307 MSN 30031969 GM5ZGXW AMD version

        Hello. The laptop freezes and resets only at low CPU usage, practically at IDLE after a few minutes. There is no problem under a load, and I benchmarked it for over an hour. I noticed that one of the CPU coils was making whining noise at low CPU usage. I previously thought it was a BIOS problem, but updated BIOS and no change. I'm thinking of changing the CPU DrMos'es there are 5 of them all together. I have already swapped the DrMOSes first one with the last one (I desoldered them and soldered in swapping DrMos no.1 with...
