Humble Richard. Great work

Rather than just listening to music, you can test them with an analog Ohm meter. If the needle doesnt move smoothly you have dirt or dead spots. It's much more accurate. Plus, you can generally measure them in circuit too.

Hi Richard great video as always - I replace faders in mixing desk all the time usually they are dirty from either beer or other spillage! I disassemble the faders by bending the metal tabs out allowing you to access the brass slider contacts and the carbon tracks - use solvent cleaner to clean the tracks and remove any other dirt or fluff from inside then use a cotton bud with switch cleaner to clean the tracks themselves - and usually does the trick - occasionally the carbon tracks get damaged from someone dropping something on the desk etc then the faders are scrap

„We have what we have, and we need to fix it“ 👍😂

Heya love to see some diffenarned repair video's and it's still electronics

Love this one.

great lesson on why not to jump to conclusions based solely on symptoms.

Would it perhaps make sense to provide additional mechanical support for the pots, e.g. by using some hot glue? I'm asking because I'm wondering what caused them to mess around with the PCB in the first place. And the only answer I can come up with is that a pretentious DJ yanked the sliders too hard and caused some initial damage. Which then got disimproved upon by their repair attempts. Now that half the vias are gone, and they're probably going to keep abusing the device, perhaps the sliders should be more... fortified?

this is class! thank you Sir Richard

nice repair

Good work sir

Hi Rich, CAIG DeoxIT Fader lube F5 or F100 is the good stuff for cleaning these controls. Do not use the Red DeoxIT D5 or D Series lube cleaner as that can attack the carbon tracks.

Sods law pops up a lot, if anything can go wrong, it will. The PCB is made of the thinest possible copper. The repair looks good.

Hi.very educated videos for new to electronics to learn and to us old class to remember.i would love to make a video on how to make isolation transformer for safe use with oscilloscope.keep doing what you do.Fredy.

That [M] logo on the faders is for Matsushita, so National and Panasonic.

Come on Richard, let's see you dance some Northern Soul 👍 I bet you can 😉❤️

Excellent! Now how about fried SMD caps? ;)

I wanted to see you repair the pots, with pc sim racing, the pots go bad all the time, i am pretty good at repairing them, after 5 years i switched to hall sensors.

A better way to test for a noisy pot is to feed a tone into it. A short break in the signal would be more obvious.

some of those circuit tracks were horrific. screwdriver damage by the looks of it

All good, so long as the customer understands there is no guarantee it will function correctly, given you don't have the whole unit to install that board and test it properly. Chances are 'the other guy' who butchered it prior is the customer attempting in-house repairs.

yeah happens every day here.Fail diy attempt by the owner or some friend,nephew ,son,cousin etc who thinks he solved electronics repair after watching an edited youtube video.Blame another technician like i care if he tried diy and failed.I tell them that its ok to tell me ,im not gonna slap their wrist for breaking something even further,its their property,they can do whatever they like with it.However many believe that you are going to charge extra if they admit DIY.I dont really care since i always charge for the repair attempt even if its a no fix,no matter if the thing died on its own,liquid damage,fail DIY etc.

Richard, love your videos :-) would you be able to tell me the model number of the infra red camera you use, or a link to it even?

I'm interested in knowing the model of the camera used for magnifying/inspecting the PCB. It looks great on video!

Looks to be a Soundcraft Spirit Powerstation 800.

Could you put a 5k signal in and look at it on a scope

Them vacume pumps are generally horrible. Ripping pads up if you not super careful. The silverstat II i the best solder sucker, been using it for 3 decades.

Some boards just seem to want to come apart sometimes

You did not solder middle pins

Wouldn't it be safer to use an oscilloscope to measure the continuity of the faders throughout their trajectory? Because the multimeter will only be able to measure continuity at specific points.

that person should never touch a solder iron ever again .. plus it is a cheap soundcraft mixer .. you probably charge more for the repair then what that thing is worth some people should never ever open things up as they do not have the IQ to do it... and yes got to start somewhere but that botch job did he do it with a 1000w welder or something jeeezzz
