Dash lights in my 2003 buick century will not dim and will only come on after I turn dome light on then off


a little complicated but here's the deal. most dash light dimmers are really a rheostat and by what you are describing, the coil portion of the rheostat is 'fried' but this will still allow the non-dimming portion of the coil to operate non-dimmed. the dome light part of this is actually another separate switch that is engaged once the max dash light adjustment is reached, it has little to do with the dimmer what-so-ever. This is at least a $200 (or more) repair from a good shop, could be even pricier at a dealership, not counting the dimmer itself.

Headlights flashing at blinker speed


Flickering headlights can get you a ticket to the policeman's ball, but more importantly, they may indicate trouble inside your car. This problem can result from many potential causes, but whatever the reason, you must identify and address it before your lights go out altogether.

97 ford thunderbird alternater trouble shooting


It sounds like your alternator is about to fail. Have it checked, I suspect that the charge voltage has dripped below 12 volts. A properly functioning alternator should put out about 13.8 volts when in charge mode.

D4dmx-md5 stop working. No schematic. Problem came slowly then it stop working. Get a bit of light on the led display Maybe a power supply problem


You did not post enough information on symptoms to get a good answer. However, the most common problem with these dimmer packs is a failure of the sermiconductor that controls the amount of power going out to the attached light. In the D4DMX, there are 4 such, of a type class of semiconductors known as "triac", part industry part BT16A (the "A" is important, as it indicates an internally insulated mounting/heatsink tab). When this part fails, the output channel stops working, but the other 3 channels continue to work. Altho rarer, it is possible for multiple channel triacs to fail. The failure of a triac is typically due to (1) attached bulb filament failure (in a manner where a filament fragment shorts across the mounting posts), (2) channel overload (eg, plugging in a greater load (significantly greater wattage) than the D4DMX channel is rated for), (3) AC power line surge. You need to be a trained & experienced ELECTRONICS (ie, NOT electrician) to accomplish this repair safely & satisfactorily, and it involves soldering & specialized test equipment.
The D4DMX series is also known for failures of its control cable interface circuitry, both for Microplex and DMX. Microplex failures is more common, as that type of interface is more sensitive to induced noise from nearby AC wiring, radio signals, and standing wave reflections from varying lengths of control cabling. DMX uses a differential control signal interface, which makes it much more immune to induced noise, but it operates at a lower signal voltage which makes it more sensitive to accidental application of improper voltages on the control cable...which often happens when someone connects the DMX ports on the dimmer pack to a Microplex connector on another pack or the control console. One clue is to look at the single tiny LED right next to the control cable connectors; if it's lit green, then the Microplex signal is detected, if it's lit red the DMX signal is detected, if it's not lit at all (off) then no signal is detected which just may be an interface circuit failure. Such problems are a bit more challenging to troubleshoot internally, and requires a proper oscilloscope or logic analyzer.
In both of the above cases, you will see what may look normal on the LED display, but the dimmer pack will not function properly.
You should describe more symptoms of your problem, such as: Are all light output channels not working, or just 1 or 2? Which control interface are your using (Microplex or DMX)? What is your LED display saying? What are the present settings programmed into your D4DMX? Are any other working channels responding to the control console normally? What is the total length your control cables, including those between serial connected ("daisy-chained") multiple D4DMX dimmer packs? Do you have any non-D4DMX dimmers in the control chain, and are they all connected using the same type of control interface (Microplex or DMX)?

Channels 3 & 4 go to full on only. They do not dim.


The electronic part (a triac) that does the actual dimming in the bad channels is shorted, so the lamp always comes on at full brightness. Unless it's a special part or the manufacturer has removed the device markings, it's possible to identify the bad parts and replace them. Electronic components are available from a number of online sources (MCM, Encompass and others), or maybe even locally. Most musician supply stores have service departments or can refer you to someone if you don't want to try repairing this yourself, or you can see what service options are listed in your manual or on the manufacturer's website.

I cant seem to get a good shot in the dim light. Somehow the program/software could not sense and adjust the lighting and focus (in auto mode).


Hi,

Automatic mode doesn't always work the best. I would recommend manually adjusting the settings for low light conditions.
