Control Board W11088499

There are a number of relays on the board that might be frozen or burned out.

Here's how to use the MU/MD key. Say you want your item that COSTS you $120 to be priced such that you end up with a 40% margin. MU'MD calculates the final price to achieve the margin.

Enter: 120 X
Enter: 40 MU'MD
Result: 200.00

Proof: 200 - 120 = 80 / 200 = 40%

Essentially the same as using the COST/ SELL/ MAR keys.

The Casio HR-100Tm manual is pretty pathetic. Expected a better one on their website, but alas.

You can get the parts at American DJ's website.

Hello,

Please check whether your ODD is ok or not?To check try to boot the machine with a bootable disk and then check if the machine is booting;ODD is fine.

Also note that audio DJ function support only cds in audio format(5-10 songs in a disk usually wav format).
It wont support MP and other formats.

Thanks

This is a wild educated guess.

I repaired a Behringer guitar amp that had a DSP effects in it (BX1200 I believe).

The effects were on a seperate board and the board had its own 5 volt power supply. The filter capacitor for the 5 volt power on the board was UNDERSIZED and it had degraded causing the 5 volts to drop out of regulation, dipping to 4 volts. This caused the DSP effects to fail.

YOUR device MAY use the same DSP OR design.

Check the 5 volt power with an OSCILLOSCOPE to look for dips below the 5 volt operating point that occur at 120 HZ.

More specifics please. Are you trying to delete tracks or albums using the dell dj buttons themselves or are you using musicmatch while the dj is docked to your computer?
Also, you might try (while docked) using dell dj explorer to delete data from your player.

live recording (using mic) can be great depending on the speakers and your position from it .(dj live up close on the speaker can be destorted) your recording setting should be 1/4 up since the dj most likely is full. TRIED NOT TO RIDE THE '0" RECORDING MARK. the bars while recording should be tapping '0'.the mic on the iriver is quite powerful . now if you are using a line in option (this will take out the liveiiness)

You need to be more specific. Does it have power? Does everything else work? MORE INFORMATION.

Thanks.

This is an issue with the main drive circuits. You have what we call the 'washing machine' affect.

Only a qualified technican can repair this for you. Not too costly, if the tech knows what to look for. If not, then he will spend many wasted hours trying to find the damaged circuits. Make sure you explain the issue to them and ask if they've fixed it before.
