Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.

Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".

Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....If this solution help you understand the problem :rate as fixya..

Good luck;

My receiver technics sa-ax720 keeps making a clicking noise and then it will say on the screen "overload" and then shut off.


try checking for broken solder connections on the amp ic's and regulators. That is a pretty common problem with these

Sherwood AX-4103 amp keeps clicking


Hello there.... Check your speaker wires and then if that doesn't do it? try replacing the fuses on the back of the amp.. make sure power is turned off and unplugged. If that doesn't work? Try one speaker at a time ... something is causing the system to short out. Hopefully it is not internally

Denon avr2312ci shuts off and blinks red


Yes that is why. The receiver is protecting itself from an un-stable load impedance which causes current/voltage spikes through the final amplifier components and proportionally through the input where the protection relay is (click),. Do not continue using the amp until you have repaired or replaced the blown speakers. A rule of thumb is to maintain 8 ohms on each speaker wire plugged into the amp. Keep that in mind or eventually you will damage it.

My receiver keeps shut'n off right *** soon as i turn it on it says"amp err" i open it n no blown fuzes or burn smells or burns or nothin out of the ordinary, except for alot of dust...... it...


I would unplug the unit and then un-hook all speaker wires from the receiver. Next power the unit back on with no speakers attached, if you still get "amp err" then you likely have a power supply or regulator problem. If the unit seems to power on ok, then add one speaker at a time and test. This receiver has a power up routine and it looks at speaker load before sending signal. If there is a short in the cable or the speakers are presenting a load below 4 ohms then the receiver will never power up correctly.
Good Luck. Hope you get your beats back.

My tuner will play for a short time (fm radio)then shut off with a loud click and the message "OVERLOAD" appears on the display. Help! Thanks.


This is a common question on this site. Amps of all types have protection circuits to keep them from doing a self meltdown. Testing follows this logic.
1. Remove all speaker wires. 2. Keep the volume down - all the way. 3. Turn the unit on. 4. If it does not trip off, then there is a problem either in a speaker or the wiring. a. Reconnect one at a time until/unless it trips off b. That will tell you where to look further.
If it does trip off, then there is an internal circuit issue in the amp and probably requires professional help to fix.

My receiver keeps clicking over to standby. This now happens at least every 5 or 10 minutes. I keep powering up again but it continues to click over to STANDBY. Please help.


Not an expert on this amp But going into standby often means the system's Protection circuit is cutting in to stop an overload condition. As a quick first thing, try disconnecting all speakers and running the unit without speakers for the 10 minute period and see if that helps.

the clicking is a power suplie overload some output amp is with problems and shutdown after overheat, when you tap is bad connection inside, normaly is related with sound off after 15min. needs to be checked by tech. to ensure perfect operation.

ITS ON STANDBY MODE & NOT ABLE TO GET ITS DISPLAY


Try this, not sure if the same would work for ya.

Swich off the amplifier.
Prior to the process check the wires connecting the speakers are not creating a short circuit which is apparently putting the amplified into a standy mode.

1. Press the "A" "B" and power key all at the same time and hold on to it.
2. The amp will go into a reset mode and will keep blinking till it gives a normal "click" sound and the amp turns on.
3. this process would take about 2 - 3 minutes.
4. You may then release the buttons.
5. If it goes into a standby mode again and does not power on, or the standby keeps blinking, get assistance from the engineer.
6. Once it is on, you shall need to do the resetting of alll the configurations done earlier.

Hope it works, it costed me 3k to get the job done.

AVR-1603 - no Sound exept over Headphones is a weak signal


First check the outputs at the output fets/transistors for any DC voltage. Reference your voltmeter to the speaker - terminal. If there is ANY DC offset, the amp is shutting down the outputs to protect your speakers from DC. Is the power supply + and - 47 volts? If only one supply is there That is your problem because the supplies should be symmetrical. Also look for any wiring problems from the amp to your speakers... any shorts? Try disconnecting all your speakers to totally eliminate any speaker problem and see if the relays still click. You should hear only ONE click when you first turn the amp on (delay of about 2-5 seconds). If they keep clicking the amp outputs are next. Also, is there any indication on the front panel of what is failing?
