You have an internal problem in the amplifier of the sub woofer box. You need to take it in to be checked at a service center, there are no quick fixes for them. Sorry,

Dave

Ikasu dvd boombox -no sound


If you have power to the unit but no sound, chances are the audio output ic has shorted causing a load, turn volume down, power off, remove speaker wires, power on, if standby light stays on audio output ic needs to be changed. If however the standby light changes or goes off it indicates a short in the wires or speaker issue, hook up one at a time to identify the problem one.

No sound coming with protection light on


It's either overheated or you may have faulty speaker wiring or a shorted speaker. These directions come from a Samson servo 120a but the theory is the same.

The following conditions will cause the Protection LED to go on:

Initial power-up: For approximately five seconds after initial power-up, the relay

speaker connection circuitry is deactivated and the speaker output is muted. If everything is operating normally, you will hear an audible click at the conclusion of this brief period, as the circuitry is activated and the Servo 120a begins delivering signal to connected speakers (at which point the Speaker LED will light if the Speaker on/off switch is in its "in" position). It is normal for the Protection LED to fade gradually after the amplifier is powered off.

Overheating: A temperature sensing device in the Servo 120a will cause the relay speaker connection circuitry to be activated (and the Protection LED to go on) whenever the operating temperature of the unit rises above a safe level. To guard against this problem, make sure the Servo 120a receives adequate ventilation on all sides ; in extreme environmental conditions, you may also

want to consider the use of cooling fans.

Severe overcurrent conditions: This occurs whenever the signal being output

from the Servo 120a rises to a level above 20% THD (Total Harmonic Distortion).

Shorted speaker cables: This will occur if, due to faulty wiring, the hot and ground signals being output by the Servo 120a short to one another.

Output impedance drops below 2 ohms: This can occur if the Servo 120a is connected to inappropriate speaker systems (see the "Setting Up and Using the Servo 120a" section in this manual for more information).

DC voltage detected at speaker output: The most likely cause of this is an internal failure. In general, any time the Protection LED lights up (other than during the approximately five seconds following initial power-up), there is reason to be concerned. If this occurs, turn the Servo 120a off immediately and carefully check all wiring and external devices in order to locate and correct the condition that caused the LED to light up in the first place.

Power light keeps on blinking on and off. when ground is disconnected light stops but subs still arent playin


A speaker cable may be short-circuited.
• A speaker output may be in contact with
the ground.
• The temperature of the internal parts may
be higher than 120°C (248°F)
• The fuse of this unit may be blown.
• The unit may be malfunctioning and
sending DC signal to the speaker output.
• The sigma servo connection may be
erroneous.

Basslink has no output, but Power LED and Servo LED always on.


Hi,

One or more of the DC to DC outputs might be bad. Check the
/- 54v on the main PCB and the /-15v on the switching controller PCB.
Losing one side of the 15v will cause the limit comparator to rail and force the servo protection, even with no input signal.

I have an Infinty Bass Link hooked up to my 2002 Honda Accord sedan for extended bass response on the standard stereo. I hook it up with premium power cables, etc...according to manual. I then hooked it up...


Hi,

Does the servo led stay on? If so, you might have a fractured solder joint. Inspect the switch control PCB for fractured solder joints and check the Positive and Negative 15v outputs on the same board.

Is the light on the infinity basslink suppose to be red or green


Hello jmw3031,

The Basslink should have both a red power LED and a green servo LED. The red LED should be on when power is applied. The green servo LED should only come on during high-level bass transients. Turn the gain down slightly if it stays on for extended periods.

Hope this helps.

Is the top and end sensor supposed to be off in servo check mode


If the tape is inside, both sensor should be OFF because both are photo diodes and will ON when receive Light.
Tape inside covers both sensors, so no light, no ON signal.

Cruise Control


My Answer:

I've only seen Cruise Controls have 1 or possibly 2 wiring problems by design.

Usually the Cruise Control Servo Unit itself if pretty darn dependable, and will outlast most everything else on the SUV/car.

The most common problem is usually a BAD GROUND wire at the CC Servo Unit itself, which is located under the hood and usually where it's mounted off to the drivers side at or near the engine firewall, or else up front nearest the battery box.

The other wiring problem might be a bad connector or dirty connection point from where the wiring harness is run into and under the steering column. That connector can be seen from under the dash area and checked pretty easily with a DVM for proper function.

With either an automatic transmission or clutch driven model there is one other "safety disengage switch" located on either the clutch pedal or else the brake pedal, and this switch (if it's not positioned properly, or defective - as in OPEN) will kill the +12-volt battery POWER going to the CC Servo Unit itself. The CC light may be ON, but there still won't be any battery power to the CC Servo Unit, causing it not to set.

On all newer generation CC units the vehicle "angle" or attitude sensor, and drive shaft VCO pickup sensor design were dropped, and instead the monitored engine speed is now taken directly from the engine's Black Box computer and used as the VCO reference. If this VCO signal is missing then the CC Servo Unit will not engage as well.

If the CC Servo Unit uses a vacuum line feed you'll need to check that as well to make sure the hose is intact and it's making a good snug connection.

If all these points show to be good - then the CC Servo Unit itself is bad and needs to be replaced. Make sure you troubleshoot everything else above first as the CC Servo Unit is no doubt pretty pricey in cost, and may not be bad at all.

Hope this solves your problem.
