You are the man, thank you for this. I hate people who say don't touch anything electronic, just replace it. This is a much better answer in my opinion-- teaching and sharing what is safe and reasonable to do.
I’m a year late but agree 💯% Personally I like to tinker and if I can fix it it’s a bonus can’t make it worse as it was already broken lol’ Also helps one learn how everything works on a board’ The sad truth with “modern day”electronics is companies either build them to fail (planed obsolescence) or they manufacture them so cheap Aka they make them not meant to be serviced’ so fixing them is near impossible’ or a new product is more “cost affective” if u can fix a tv board absolutely worth it! For a person who doesn’t know how not worth it as a new TV will cost about what a tech will charge to fix it’ For me I agree with u all the way’ I would repair an older electronic any day if the week over goi g for modern day cheap crap’ same with appliances 80s appliance are an eye sore but they were built like a tank! 😂 Take care brother!
What's annoying is that some multimeters don't have a capacitance option, like mine! Excellent video all the same, I like your straight forward explainations.
This was extremely helpful. thank you! I had received a board from a glass top stove that supposedly didn't work. fortunately all the components on the board tested out perfect. But unfortunately these people had German roaches and all the roach crap was fouling the whole system up. I clean all the feces off of the board and it worked perfectly. So people if you have a roach problem and your appliances don't work, that might be the problem. Because roach crap really does screw the whole system up. LOL
Thanks for showing a deep inspection. So far, I was able to find faulty board parts by visual inspection (e.g. blowed caps or other parts where the smoke "escaped" )
Excellent video easy explanation brilliant. Quick q i have the fluke 117 there is no "rel" button on this meter to zero out the leads. Is it possible to zero the leads ? As when i set the meter to ohms and check the leads i get a reading of o.2 ohms and can't reset it to zero.
@catzndolz past tense: learnt; past participle: learnt 1. gain or acquire knowledge of or skill in (something) by study, experience, or being taught. You clearly confused!!! Go learn🤣
For process control techs using a Fluke, an easy fault to find is that you left the dial on milliAmps and then connected 120 VAC. Yeh, ya might wanna buy at least of those little custom fuses.
I have a electric shaver that doesnt charge anymore , i dont think its bcuz the battery is dead, i think its a technical issue that send the power directly to the motor instead of the battery And when its pluged into outlet, the motor starts but gradually it gets more intense, so much that i think it might damage the motor and i get it out of the outlet Any help? Do u have a video about it ? Or can u tell me what should i search to find the solution ?
but dont diodes have different values? i have 2 diodes that have the normal .550 voltage drop and two others that have a .300 voltage drop? is that bad?
Great video but a tip about capacitors is that if its blown the silver top might be dome shaped or there is electrlytic fluid leak. Obviously this is not for solid state capacitors
Analog multimeters are better for this purpose, even if they are inaccurate, and old. Better response and you can test, how the device behaves. Analog multimeters are also ideal to revive locked devices or components. I could restart the charging of a locked ZTE phone, by tapping the port and batt connections with a multimeter, and it started charging. Digital multimeters are better for everything else.
How does the low impedance mode discharge the cap? I had issues where i worked on a PSU and measured 0.6v and still got a shock, not sure why maybe i measured it wrong?, I put my black probe on a random ground however, rather than the capacitors ground pin, could that be why i got a wrong reading?
It just feels a bit too vague and rushed for a "Basic" tutorial; ie. You take a reading and say "Looks good!" but you never explain what a bad reading would look like or why the readings you took are in fact good.
It's a hair above basic. The reason the readings were good is due to continuity or lack of. And also because the resistances were within the expected ranges. It's VERY important when dealing with electrical components to expect a reading, in the case of the resistors you can consult a chart online for the colour stripes and compare to your readings.. in general if a reading is within 10% of what's expected the component is considered good. :)
@@Grimes907 thank you for the pleasant response. It's my life goal to try to be logical and helpful on the internet.. its so important that we turn it into the usefull thing it's meant to be and disperse from the toxicity of it.. thanks for being awesome :)
@@MrDmadness thanks for your response. My problem is not measuring components, but correct measuring in circuit. What can we expect to correctly test in circuit with accuracy and what needs to be removed for accuracy. As you and I both know, the majority of faults is with shorted or leakey caps. How can these be measured inline with accuracy?
@@jefffoster3557 an oscilloscope will tell you anything you need to know. With a volt meter you can test capacitors with the cap funcation ( sometimes paired with the diode function ) to co pare their readings with their identifying markers. For voltage on a board you need 2 points of contact ( one could be ground ) and touch a line trace anywhere understanding that the meter is giving you the differential between those points( eg. If you check the same live wire it will read 0volts as there no differential ) to read amperage in a live circuit is harder, there is a meter specifically for this that's expensive and who's name escapes me at present though as mentioned an oscilloscope can do all functions. One of the first things I learned doing controls wiring is that you should never take a reading without first having an expectation of what it SHOULD be. For resistance readings ( never take these on a live circuit ) it's as simple at touching 2 points and reading the reading, having a wiring diagram helps to see if you are reading g resistance through a component like a mossfet or otherwise. The basic triangle for figuring electrical readings out ( if you have 2 ) is this Volts over amps x ohms , E.g.. 120 vac 15 amp breaker == 8 ohms resistance .. this means that if you have greater than 8 ohms resistance your circuit will not function at all as electrons cannot overcome the resistance Remember also this ( compare ele tricity to water ) Amps = flow ( same as gpm or any other flow in water ) Volts = electrical pressure ( psi in air or water ) Ohms = resistance ( same as friction allowances In plumbing ) Electricians have switches and breakers Plumbers have valves and main isolation They are basically the exact same thing, except specific to their conveyed medium . :)
