Onkyo DR-S2.2 blink and shuts off

I own a DR-S2.2 and for some reason my unit blinks and shuts off. I have tried to plug it in by itself and in different socket but it does the same thing no matter where I plug it in. I checked the fuses and they were fine please help

    I was watching and BAM! It now won't go off standby. The manual's troubleshooting says that the amplifier protection circuitry has been activated and to contact an Onkyo service center. There must be a workaround for this.

    My system, Onkyo DR-S2.2, plays for a few minutes and then pops and goes to standby. I have not found a solution yet.

    Mine does the exact same thing. When I turn it on it stays on for about 5 seconds then shuts off and there is a red light that just blinks. PLEASE HELP.

Most common failure is the audio amp IC, reference # Q5001, which is an STK402-950 (Onkyo Pt. # 222123). Typically fails as a result of excessive volume levels or as a result of problems with the speakers or their wires. If you're technically inclined, the part can be had from various vendors & is fairly straightforward to replace once the complex disassembly required to access the PCB this IC resides on is accomplished, using standard soldering skills. A repair of this type by a reputable servicer may be more effective for non-technical folks, as typically can be accomplished for $200 or less, much less than replacement cost...

    That seemed to be the offender in my case. I gave that STK402-950 the Arthur Fonzerelli with the back of the screwdriver, and it went right back to perfect working order! (Of course, this is in NO WAY the proper resolution, but I'll take it for as long as it will last!)

    Thanks for the tip!

SOURCE: Problems with Onkyo DR-S2.2

I am trying to hook me DR-S2.2 receiver up with some existing speakers I found in my new house, but can't seem to get the center speaker to work. What mode does it have to be in so I can see if the center speaker works?

Subwoofer issues


Hi,

The fuse blows when the current that passes through it are beyond its rating. This could be brought about by excessive consumption of the load, in this case the amplifier powering the sub-woofer.

Repairs would involve component level and require that you be familiar with electronic components and circuitry, use of a DVM and a soldering iron. Often it is just the finals that needs to be replaced. Of course we cannot discount the possibility of other components or section such as the power supply.

The smoke indicates something heating up such as a resistor or diode or a capacitor.

Should you be uncomfortable opening the unit and doing a DIY (do-it-yourself), then perhaps you need to seek the services of a qualified professional.

Should the downtime and cost of repair be no longer economically reasonable, purchase of a new unit might save you further trouble.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Problems with Onkyo DR-S2.2


sounds like you have uneven flow of electricity. Try to plug the receiver in its own power socket

also make sure it has plenty of clearance for airflow b/c the receiver is shutting down to stop further damage of the receiver either b/c of heat or power surges.

good luck
