Hi Tom,

The fuse you may be referring from the power supply is not

used(none) instead a CB1 or circuit breaker is installed.

These breaker is in series with the power transformer ( trace it).


Disconnect the AC outputs of the power transformer when trying to

reset.( of course with the unit unplugged ).


Measure the output AC voltages, if it is OK

Be happy partially!


Next would be.....


Check for possible shorts on the Positive and Negative Supply

rails to ground or speaker out, for what might have caused the

breaker to tripped.


And these wont be easy troubleshooting , Good luck!!


thanks for choosing Fixya for assistance.

SOURCE: There is a red light shinig inside my CROWN XLS

Lots of electronics have lights (LEDs) that turn on when they are plugged it. Most people just don't notice them. If it is working properly, then the light is normal.

SOURCE: The fault light immediately comes on my Crown XLS

Hi try disconnecting the speaker outs and turn off bridge (if its on) If it doesnt work still, then suggest direct to a crown agent. The amp has a 3 year no fault warranty. Hopefully its still in!

All the best

SOURCE: No power to Crown XLS 602 Amplifier

Hi...

There may be some internal fuses on that unit.

You can open it by taking the cover off and looking for fuses and discolored parts.

It may have a thermal fuse on the power transformer which then will require service

SOURCE: my crown 602 xls tripped a breaker, I reset

They use a breaker instead of a fuse.

CONDITION: No

power to the amplifier.

POSSIBLE REASON:

• The amplifier's Power switch is off.

• The amplifier is not plugged into the power receptacle.

• The amplifier's high-voltage power supply circuit breaker has tripped. Verify that the AC mains

voltage is correct, then press the Circuit Breaker button on the back panel.


Take it to the ER.

I have a Crown XLS 802 amp that works fine but the fans do not work. They, however, are not frozen. Any help is appreciated. Jim


It is capable of detecting cooling fan failure so I would presume it hasn't decided to engage the fans yet.

cd changer is grounded through the plug, And it should have it's own fuse -- so if you are not getting power to the unit, look for a in-line fuse to the changer itself.

I need to replace the fuse for a used Marshall MG100HDFX that I bought. Where is the fuse located inside the head?


If the fuse is blown make sure the reason it blew is repaired before replacing the fuse. Start the amp up after replacing it with a 100 Watt light bulb in series with the hot side of the power into the unit. This will act as a current limiter to verify it is repaired and will not blow the fuse. When you open the unit the fuse will be obvious... Follow the hot side of the power cord, through the switch to the fuse.
