F" if anyone can help, I would be higly appreciated. I have fixed a few XT power supplies, if you replace the caps, it is almost a guaranteed fix. Hello, It was a long time ago and unfortunately I was not able to fix it yet. I remember at the time I replaced all electrolytic capacitors. Then when I was testing there was a short circuit somewhere, and it never worked after.
I think some IC or transistor might have burned and with the schematic it would be easier to troubleshoot and find the cause, if it was a linear PSU it would be easy without the schematic but this is a switching PSU. Anyone know where I could get a schematic for this?
Apparently it was very simple and went smoothly. Lots quieter too. Yes I will replace it for another PSU. A general one. The manual contains diagrams of both the BRC front panel controls and the rear panel interface.
Moreover, the manual contains several connection diagrams for a variety of recording situations. To determine which type of sync cable is the correct one, look at the cable's 9 pin connectors. If the word "Alesis" is stamped on each side of both connectors, then it is of the correct variety. However, there are no serviceable parts within this supply. Alesis purchases this supply off-the-shelf from an outside vendor.
If there is a problem with the power supply, It is usually less time consuming to replace the whole power supply. Page Video Interface 2. This signal then feeds a circuit which is used to extract a vertical sync signal. Page Brc Repair BRC, refer to figure for a pictorial representation of the text that follows. Page Brc Internal Cabling 3. The number of wires in each cable depends on the PCB. In a similar manner to the method described for the LEDs, the processor uses U5 and U7 both HC flip flops to scan each of the columns for a depressed switch by pulling a low on one column at a time.
When a switch is pressed in a column that is low, it creates a current on that specific row, causing that row normally high to pull low. Page 17 During the course of development of the BRC, Alesis has found two types of symptoms which indicate specific problems. These are listed below: 1. Basic functions are not working properly: In this scenario, the first things that should be checked are the voltage of the battery and the voltage at U8, pin Check both of these voltages with power off.
Page Vco Circuit Troubleshooting For BRCs that intermittently reset, there is no concrete solution other than replacing the power supply. However, this solution does not always work.
If you have a unit which is exhibiting this symptom and it cannot be resolved with a new power supply, contact Alesis Product Support so that this unit can be replaced. Appendix E contains the test procedure which should be conducted on every BRC serviced. Furthermore, within the BRC software are a number of self test routines which can be implemented to aid in determining various problems with the unit.
