There maybe a short in the wire, try using another wire with the same rating and it should power on. If not then it maybe a defect with the product.

It sounds like the power connector is NOT making solid contact, but only toches briefly as you insert connector. Often these connectors have problems if the size if the pin vs the hole in the connector is not compatible. The OTHER common problem is that the solder where the connector attaches to the circuit board breaks loose. When you insert the connector, the broken solder joint briefly touches and cause the unit to blink and then the connection breaks again. Open unit and assess the connection.

One other common problem is the cord breaks at the flex point where it is molded into the connector. as you move it, it can breifly touch inside the insulation and then seperate again.

Hi. My boss br 1600 will n ot start. I turn on the power source and it will blink for a split second and then nothing. I checked for loose connections but everything seems ok. Any suggestions?

I have this problem with mine. I've did some research and with the boss br 600 this problem can arise quite often .it's caused by a faulty power diode apparently except in that case I've never heard ofrom the screen blinking at all (which my 1600 also does) I wonder I'd this problem can be the same for a br 600 as the br 600

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.

Probably NOT a transformer. Most likely in the power amp. Many have a thermal cutout that shuts the thing down when the chip/stick gets to hot. Your description leaves some questions... IF you don't get anything at all out of the left, then look first for a short from the amp to the output jack. This probably has a dual chip amp in it and half that chip may be bad heating up and shutting the whole thing down.

A BARE USB cable should NOT have caused any problem. If it was an "Active" type cable that does a conversion something might have happened. Another possibility is you had a static charge on you and the static did damage. Another possibility is if the connector really wasn't the SAME type and pins were shorted. Turn off the power and with a bright light compare the connectors to see if this last possibility might be the case. Also look for signs of arcing or bent pins. If the connector was forced, then it is possible the circuit board was cracked.. In any event servicing is required.

Search the web for a "Factory Reset" sequence for the unit. Usually you have to hold a button or a combination as you turn power on.
