Question about RCA RT2280 System

1 Answer

"Check SPK" The receiver was working and would radomly shut off. It would shut off easier the louder the volume was. The other day it shut off and when powered back up the display reads "Check SPK". I removed all the speaker wires and tried to power back up but it says the same thing. Any ideas?

    Check SPK -- I need a schematic. It may be a emitter resistor

It may have been a bad solder connection on an emitter resistor, now it probably needs output transistors and a resistor or two.

Make sure it's not a speaker disconnect all speakers and power on if it still displays "check spk" it needs service. Est $100 to $140 Total

HI i have my PIONEER XV-DV77 BUT NOW ONCE I INCREASE VOLUME THE SYSTEM CUT OFF PLEASE HELP?


You may have a short in one of your speaker wires, and the receiver is protecting itself, or you may have too many speakers connected, or be trying to make the sound louder than your receive can handle.

My onkyo ht-r590 goes on then shuts off right away.


The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.

I have a Sansui RZ-7001 home theater system but cannot get surround sound when connecting my LG Blu-ray BD 550 to it. What am I doing wrong?


fred i dutoi,

Check your connections first. Make sure your input on the Sansui RZ-7001 menu is selected to dvd. Also, make sure the blue ray cables are also inserted in the correct inputs on the rear of the receiver(dvd input). via. rca cables(red, white & yellow) the yellow is the video, hdmi, or optical. If you do not hear sounds coming from your speakers you need to check the separate volume levels for the speakers within the receiver itself. Front and rears having different volume levels within the receiver. Hope this helps. Also make sure you check the volume on the dvd player. Thanks for visiting FixYa.com. Have a great day !

I have had my Sony DAVHDX285 DVD Home Theatre for about one year. It has started to hum. The louder I turn the volume the louder it hums. It is coming from all speakers.


This is commonly caused by out of regulation supply to your output IC. The reason why is your unit have the ff fault:
1. Dry joints on the main filter electrolytic capacitor, also on the amplifier cirtcuit board. Cold solder is hart to spot so you need to locate it perfectly.
2. Leaky filter capacitor on the B+ section,pre-amplifier section,output section.
This is not diy and i've advice you to look for a qualified tech to isolate the problem.
Have a nice day!
Thanks for using fixya.

My system shot down during a movie


The reason why your receiver is going in protect is because there is a short circuit happening. This would either be on your speaker wires, speakers or receiver itself. What you want to do to check would be:
1. Unhook all sources and speakers from your receiver.
2. Turn on your receiver and crank up the volume to maximum, if your receiver does not shutdown or go on protect then the receiver is OK. If it does shutdown and go on protect then its an internal problem on the receiver and you would need to send that over to an authorized service center.
3. Hook up a source and 1 speaker. Play something from the source or the fm tuner, Crank Up the volume to about 46 or 47 volume. If the receiver does not shutdown, its good.
4. Hook up a second speaker and repeat the process until you encounter the pop and shut down
if for example you encounter the pop on the 4th speaker, try changing the speaker wires.
5. If the receiver still shuts down then it would be a short on the speaker itself and it would need to go to an authorized service center.

Power will shut down after few minutes when volume reaches 12


If you check at the back of your hi-fi, you'll see a projection at the top where the cooler fan is located. The most likely reason is that your fan is not working (as required). In this system, the fan is turned on automatically at high volumes >=10, because then, the amplifier starts to get a temperature rise and without proper cooling the system might fault.
Try check and see if at these high volumes the fan is running, if not, then that's what needs to be fixed. Alternatively you can try running an external fan to see if it will produce the desired cooling effect.

Music track is heard, but dialogue is not


It sounds like your CENTER channel is not connected properly.

Check the connection to the speaker itself, and at the connection to the back of the Sony.
