The output transistors are blown in one or more channels also the driver transistors are blown in the same channel.

you can find this problem real easy using a DVOM (digital volt ohm meter) on the continuity test(BEEP).

start be removing the amp section from the receiver and laying it on the table bench whatever no going from B-C and C-E if any beeb there junk and the driver transistors are also and there are a few resistors that are junk.

parts list

2@2sd2390 sanken get from newark and only newark/farnell
2@2sb1560 sanken get from newark and only newark/farnell
2@2sd947 from newark
4@ 2sc1841 or 2sc1845 to replace 2sc1845
4@ 2sa998 or 2sa992 to replace 2sa992
8@ .22 ohm 1/4 watt metal film resistor 1%
2@ 4.7 ohm 1/4 watt metal film resistor 1%

this is a parts list for 2 channels
only get the powertransistors (the sanken) from newark any others i have found as counterfeit and destroy stuff and dont work

i dont remember location #'s on the board but

My Insignia NS-R5100 receiver goes into standby mode a couple of seconds after turning it on.


This happens because of internal overheating - clean the air vents and if you have covered the receiver with a cloth please remove the cloth your problem could be resolved

My stand by light flashes on my onkyo tx-sr501


Check output transistors for short, change emitter resistors

Probably a short in the amp that will need to be repaired.

I have a Kenwood VR-804 surround system receiver. Stand by light keeps blinking when turned on but no sound no nothing when turned on just powers up for a few seconds then shuts off with light blinking. I...


Blinking indicates that the power source has shut itself down because another component has died and it's shorting it. Unless you have experience in electronics it's time to take the receiver to a repair shop.

Power light is flashing and power won't turn on


these a couple things you can try to reset,if resetting dont work you will have a amp problem.Try pushing and holding down these 3 buttons s.speaker b and att and exit buttons for at least 3 sec or more.should reset.If not also try pushing and holding down mult speaker and exit and att buttons together for at least 3 or more seconds.if still shuts down you will have shorted transistors inside of unit.

Denon avr-1706 receiver just shuts off


This sounds like the amps protector circuit has been activated due to thermal overload. switch it off for an hour or more to let it cool down, make sure your spkrs are connected properly, don't parallel. Try using a fan on the unit to get that heat away. Get a techie friend to give the insides a once over, and clear away any dust that has built up.

hope this is of some help,
Cheers Kimbo.

I have a fm-am receiver #ns-R2000, I push the power button & it shuts down immediatly, What could be the salution?


The receiver is going into a protection mode. This happens because there is a failure either inside the unit itself or in something attached to it (such as the speakers).

A quick and easy thing to try is to disconnect all of the speaker wires. If your NS-R2000 now stays on, carefully examine all of the speaker wiring to be sure it is not shorted. Also check the speakers to be sure they work properly.

Insignia NS-R2000 receiver


Check the impedance ratings of your speakers. Sherwood, the actual manufacturer of the NS-R2000 receiver, suggests that you use speakers with an eight ohm impedance if you have only one pair attached. If you have two pairs of speakers attached, the impedance rating of each pair should be sixteen ohms.

This is because Sherwood wired the receiver such that an additional pair of speakers is placed in a parallel circuit to the first set. When this is done, the impedance (resistance) of the load seen by the amplifier drops. As resistance drops, you get closer to a short circuit (no appreciable resistance).

Many other receivers wire the speakers in series, which causes the impedance to go up.

Personal experience seems to suggest that the amplifier is OK with a four ohm load on it. It does run warmer with a four ohm load, which is what you'd expect. It's when you have multiple sets of four ohm rated speakers that you will get into trouble, as this means the receiver only sees a two ohm load. This will cause overheating and shutdown.

At this point the power transistors in the amplifier may have been damaged. It may require repair. Fortunately, replacement parts are readily available (though not from Sherwood or Insignia). If it continues to shut down, stop using it. You could end up burning out your speakers.
