Protect is an error code for short
and or overload. This will appear once the processor sense a malfunction
either on the power supply or on the load (high chance is the output IC). DIY
steps are as follow to determine where the fault is : 1. Allow the unit to cool
down for an hour. Give proper
ventilation and keep away all
obstruction from the vent to have a sufficient air flow. 2. Disconnect one at a
time the speakers, inputs, from the unit while powering it on.
If the unit back to normal again then you've confirmed that any of
the above caused the error code. If #1 is the caused, you have to check also
the exhaust fan, clean it
as much as possible, replaced if faulty. If #2 is the caused (speaker) check
the wire and speakers for short,
(input) check the RCA cord for short or replaced if necessary.
If the above simple fix didn't cure the error code, you can try
the next steps if you are an electronicsenthusiast.
Now after removing the cover, you have to concentrate first on the power supply
board. Look for bulged electrolytic capacitor. Leaky
capacitor will affect the regulation
of the supply and will
trigger the error code. Look for dry
joints. Check it also in the pre-amplifier stage, main output board where a
big heat sink is located. Next disable the output amplifier stage by
disconnecting the supply. If the unit come out, make some re-soldering on the
board, spot the cold solder and dry joints and then try to connect
again. If the error code appear again, high chance that your output IC is faulty but still to be confirmed.
Using the disoldering pump and soldering iron pull-out the output IC from the board then try
the unit. If the error code disappear, confirmed that your IC is faulty.After
trying the abovesteps-by-steps guide and
still the symptoms persist this is the time for you to send it to repair shop. Remember that your
unit has a lot of parts and only some basic steps have done, leave the expert to troubleshoot the entire unit.
Give a thumbs up if you find it useful.
Have a nice day!
