Question about Mackie 1604 Vlz3 16 Channel Mixer

1 Answer

Took apart and cleaned all my ribbon cable connectors (all off at once). Also took off and cleaned and reseated all molex connectors. Now back together but....solo light on all channels is lit with nothing soloed and soloing or muting a channel has no effect. Something crossed in ribbons or through the path of the molex connectors?

    All solo lights stay lit regardless of position of solo buttons. With all channels muted, no red lights come on. This happened after reseating all ribbon and molex connectors. Was working fine when I broke it down to try and "heal" the intermittent problems that seemed to be being caused by corrosion on ribbon cable connectors. I'm trying to narrow down the spectrum of things that might have been changed through this process. I can't seem to locate a diagram showing which ribbon cables go where?

A few questions first:

1) Does this effect the functioning of the "solo" at all? (ie is the light on always but without effect and can you select solo using the pushbutton?) We need to determine whether or not the problem is a funcitonal one or just the indicators being lit when they shouldn't be.

2) Are there any other symptoms at all? Any other lights effected at all or any functions not working as expected?

I will look up the prints for this, but I need to narrow down the search a bit. Gaining access to the board is not quick as all of the knobs need to be removed and all of the control nuts removed as well. If we can narrow this down a bit, you may be able to avoid that.

Please post up the info requested and I'll pull up the prints.

Thanks,
Dan

I have I Technics PR-305 Digital Piano. I took it apart to try to clean the rubber contacts with rubbing alcohol. It improve some what, then later on I turned on my Technics R-305 Digital Piano.


I would suggest taking it into the nearest factory authorized repair center. Go to the Technics web site to find one in your area.

TD20 backing voice plays on everything no matter what...


no matter what pad i hit the slapbass wave sound would play..
i unplugged all midi connections..
i turned the backing parts volume down..
i removed all my patterns from the kit...
i did a factory reset...
and there it was STILL!! dang it!!
after calling Roland and hearing they have never heard of this problem before
i took the unit apart and removed the backup battery.
( didnt want to send my unit off..omg i am broke enough.)
i also pulled the ribbon cables from their holders and and then i put everything back...it factory reset when i turned it on..
(yes i had myown personal backups beforehand)
BooM! Mr TD20 was back without that slapbass wave! yahooo!
i dont know what caused it, but i was doing some major midi routing
experiments with my comp thru Sonar6P, midiman 4x4, and my Roland VSynth...and it did just kind of show up at some point when i had the backing voices turned down i guess..
it still persisted even after the TD20 was turned off for a day and half and i turned it back on to see if it still was happening...yep, i was hoping it would fix itself..lol..i hope this helps fellow musicians..play on!!

Marshall Amp Quit


According to the schematic, once the signal is initially amplified (also where the LED shows signal), the audio is sent to the send/return jacks (shown on pg3-C7). A quick test to see if audio exists at the insert point will require an insert cable. An insert cable can be a balanced 1/4" cable which splits out to two mono 1/4" connectors or a pair of RCA's. Connect one of the insert outputs to a console (if 1/4" cable) or a tape loop on a home stereo receiver (if send cable splits out to RCA's) and see if you've got sound when playing your guitar (with LED on the Marshall showing signal). If no sound, go to (A) below. If you have sound, go to (B) below.
(A) Ten pin connector labelled CON2 (shown on pg5-B1). Make sure connector is tightly seated and that the pins on the jack and the female connectors in the plug are clean and that good contact is being made.
(B) Twelve pin connector labelled CON1 (shown on pg5-B4). This is the DFX board - make sure this is tight and well seated.

According to the schematic there are voltages seen at several of the connection points previously mentioned. If you have a multimeter and are qualified and careful - check to make sure the voltages are present as shown.

If you're not qualified - meaning you have little or no experience - STOP and refer this repair to a qualified bench tech. They get paid to keep the magic smoke inside the amplifier. You may end up damaging things worse or even beyond repair or even damaging yourself.

My Mackie cfx12 will only work when the effects are on. What might be the problem?


Are you able to get a dry mix under these circumstances? If it is simply a dry version of the wet signal as you have turned the effects off yes it is possible a ribbon cable has come loose but it is more likely that an IC has died, this is not uncommon in these and they exhibit a range of symptoms including yours. If yea are happy to take apart and have a tame service centre this should save you quite a bit as the biggest cost is dismantling and rebuilding. As this is not unusual issue they should be able to fix quite easily

I own a Korg Triton Classic. I just replaced the touch screen on it. Now it wont read the floppy disks...any suggestions


It is VERY easy to not have gotten the cables back and seated completely for the floppy disk. ALSO it is very easy to damage the ribbon cables on floppy drives by pulling at the edges of the ribbon to pull connectors off. One MUST distrbute the force all across the cable as it is easy o damage the connections in the connector for the wires near the edge. It is also easy to damage the pins on floppy drive connectors. You will need to reopen the unit and check the cables INCLUDING the little power cable to the drive. If you have damaged the ribbon cable you can either replace it or possibly get another connector and put it on the cable right next to the one with the problem and crimp it in a vise... These are an insulation displacement type so you need to get it on straight and ALSO verify the index is the right direction before crimping. For your problem think cables, cables, cables...

My yamaha psr 420 has most of the middle keys not producing any sound when pressed. The others too produce an abnormaly high sound when pressed. Please whats wrong and how do i solve this problem?


Your key contacts have gotten dirty. Two contacts per key are used to sense velocity and if one doesn't work the sound will be full velocity and loud.

The contacts are conductive rubber "pills" in silicone rubber domes that the key presses down onto circuit board traces under the keys. Clean both the "pills" and the black portion of the circuit board GENTLY using ONLY 99% isoprophyl alcohol and QTips. There is a lot of disassembly required and one has to keep track of where the screws go and length and thread type to re-assemble after cleaning. Also great care must be taken to not damage the ribbon cablles connecting the top and bottom halves of the case.

Marshall MG250dfx's sound fades out


I have read that the problem is in the FX send/return jacks which oxidize if not used much. All you have to do, apparently, is ram a jack plug in and out a bunch of times. This breaks up the oxidation, and allows the amp to work properly again.

Hello, Effects and EQ hook up problem


Many of those connections REQUIRE using TRS cables (stereo style) rather than TS cables (mono style). It is possible you have mixed the cables if it worked before.

Any cable plugged into an "insert" should be a TRS (tip-ring-sleeve) cable.

Look up these connections in your 1604 manual.

My Roland Rd-500 has no sound....the factory demo


You either did not get the ribbon cable seated OR got it upside down.

If this cable is the flat ribbon with exposed solder plated points of contact, OFTEN those connectors have a latch to release by GENTLY moving tabs on eaither side in the direction of pulling the cable out. This lock MUST be moved out slightly to allow the cable to seat properly. The solder plated contacts will be FULLY into the connector when seated properly.

These cables ALSO can be inserted backwards and NO connection will be made.

Odd channels go out 1,3,5.....


Unless you are in super humid environment, this is more likely a crack in the circuit board OR a bad connector on a ribbon cable. Also BROKEN or cold solder joint for a connector pin through the circuit board.

Good way to cause this with ribbon cables is to NOT distribute the load when pulling them off. Often the wires near the edge are stretched and make poor contact with the little forks that pierce the insulation.

CRC226 is a good product to use for contacts. Available at Home Depot in the electrical department. Blue spray can. Use sparingly.
