How do u check pcb board on musical equipment and on other equipment the only tool i have to check is a Fluke Multimeter but is there any other stuff that is need to inspect and Diag. these boards ple

Looking up electrical schematic on the pcb board online and i had ask gemini tech support for it and numark tech support for the other stuff too

    If you know the Model of your 'Fluke' you might be able to find something specific for that model..

    Unlike say clockwork, electronics deal with electrical currents and 'signals' which cannot be seen or sensed adequately and like a blind man with a stick, 'instruments' are used to explore how things are working o or not. After a good multimeter, a simple oscilloscope is a very useful "eye" into the workings of equipment. You do have to understand the basics of electricity such as power sources such as line power and batteries, resistances, capacitors, bulbs, conductors, insulators, electromagnetism, transformers, semi-conductors and understand concepts such as Resistance and Impedance, Voltage, DC and AC and Watts in circuits. Firstly PERSONAL SAFETY is paramount.. Next know how and how not to damge either the test equipment or the device(s) under test..

    Electricity is less than two hundred years old and Electronics barely 100 years old and a good approch is a historical one, starting with Volta, Oersted and and Faraday back in the early 1800's..

One of the first things a technician does with a voltmeter it to check 'all the voltages' in a system are correct..

Even without a specific circuit diagram for the board, 'Applications Notes' for chips and seminconductors will give nominal expected voltages in a working circuit.

Remember you can burn out the meter by connecting it to any source of current when on the Ampere or Ohm settings.
Technicians usially start at a high (highest) Voltage range setting and work downwards..

Providing the maximum Voltage is not exceeded on any range, whether it is AC or DC will not damage the meter.

'Fluke' by the way are a 'top end' professional product - check the price ;)

Testimonial: "Ok but like u said to me start with the highest and then work down ward but how do i do this like i said i do have a fluke meter but how do i do it and where do start at? do i need to know the ranges for chips and seminconductors ,is there a chart with the ranges of all these type of component"

You need at least some basic understanding of electronics and components before troubleshooting pcb boards.
Either ask someone that knows to give you a hand and guidance or do some courses.

Power switch for Casio key board not switching


Without knowing the model, age of the keyboard if it is moved a lot, etc it's hard to say. Most common problems are damaged power jack(or cracked trace on the supply board near the jack ), bad AC adapter, bad power supply board(shorted semiconductor, regulator, etc ) and rarely a bad power switch. You could try a new ac adapter but it might be a waste of money(if you have access to a multimeter check the output of the adapter before buying a new one).

I have a Crate g120 cxl guitar amp. it is switching between channels on it's own. (no footswitch)


Hello Jamie.
Your right, it is not rocket science, this is way bigger and funnier!
Now, that you took apart the chasis fron the cabinet, you may try testing if the channel switching occurs when you hit the Printed Circuit board with some tool like the handle of a screwdriver. you can try with light hits and different places of the PCB while watching what happens in the front panel light. also you can try bending the PCB with your hand to see what happens, if the switching occurs, maybe you have a cracked solder on the pedal jack or in any component related to the switching circuit, in this case, you will have to pull out the pcb, and re-solder those points that can be cracked. Using a magnifiying glass is very helpful in looking for those cracked solders.
Good luck and best wishes.

Where can I find the entire circuit board for TRUTH B2031A


Unfortunately Behringer equipment is hard to get parts for generically. You may be able to order the whole amp from behringer but I doubt it. I have had lots of problems repairing them for that reason and I will no longer use any of their stuff. The IC's could be repaired but can't find any record or crossover to any of their output transistors. It appears they are custom made for Behringer. Sorry, I can't help any more than that.

No more subs in jbl prx-512m


First check the speaker with a multimeter.

If it is OK, then check/repair the Class D amp that drives the speaker,

up to the input stage.


There are board part numbers printed on the PCB and some are

available on line.

Have a tech to guide you ,should you feel to Diy.

The green light flashes with no fan noise at all or any sound


You have a bad power circuit board. if you are tech-inclined,you can open the mixer's rear cover and check for bulging/leaking capacitors on the board. they will need to be replaced. Or just order a new PCB from Peavey. Rodger, in tech support, will be happy to help.

Model: Mackie DFX-6 Hi, I have a problem with this unit. The main output is dead but the phones output is OK. What seems to be the problem?


Check the power going to the main output with a multimeter. It may be a simple fuse or the output board may have come disconnected from the main board.

Make sure you are using balanced lines, especially to the power amps. ALSO make sure ALL interconnected equipment is powered from the SAME receptacle or source, even if it means running extension to where the amps are powered. Ground loops are a pain and can cause serious damage to your equipment.

Not getting started even after connecting to power supply


Make sure that the power comes into the board from the adapter unit. So check the voltage to the keyboard.
If not present check adapter for failure ;If SMPS type check this link:

http://www.fixya.com/support/r5826301-working_switch_mode_power_supplies

If otherwise you must open to check the power to the incoming board, the regulator , the supply to the main switch and the power to the main board, the synthesizer section/processing board. remove and plug back all connections, if not there are errors in the PCB.

Digitech RP 90 foot switch is not working


I removed the back cover, unscrewed the two (of 4) screws holding down the circuit board, replaced them again, and it worked fine.
