No! I'am afraid not, if you have checked your wires carefully and it checked, the audio output semiconductors will require a technician to remedy the problem.

My amplifier cuts out and displays the message "check sp cable", what does it mean?

Hi there,

It simply means to check your (sp)eaker cables. It is likely that one of your speaker cables is damaged or not correctly connected. This is causing an overload in the receiver and the cut-out indicates the receiver has gone into 'self-protect' mode, to prevent damage to the internal components.

This could happen if you have cross-wired + and - to one or more of the speakers. It could also be that a cable to one of the speakers has been partially severed and +/- are shorted together or it could be as simple as one of the speaker connections having become detached. Speaker connections are polarised positive + and negative - the same as your household electrics and need to be wired to the correct poles.

To fix this problem, you should initially check all of the speaker connections at both the receiver and speaker ends. Make sure everything is properly connected and that + and - on the receiver are correctly wired to + and - on all speakers. If all of the connections are correct and the error message persists, disconnect each speaker one at a time, reset the receiver and test again.

If you disconnect a particular speaker and the error message no longer appears, you have found the cause of the problem. Examine the cable for any sign of damage and replace the cable. If there is no visible damage, it is still advisable to replace the cable for this speaker as damaged cables are not always visible to the eye.

Please check all of your speakers as above, then let me know if you need further assistance. The message could be erroneous and may indicate a fault with the receiver.

Hope this helps.


Connecting 5.1 speakers it comes up with error message: WA1- out of phase. I have rechecked all the speakers and it is not a problem with the connection. It is the front speakers that seem to be the...

It's telling you that based on its diagnostics the speakers are wired Out of Phase with each other. Carefully recheck the polarity of the speaker wring: + to +; - to -.

How do I turn off the sound alert whenever a text message is sent? But I need a sound alert whenever I receive a text message.

Try switching off the receiving of delivery report upon sending a message. This you will find in message settings.

On display appears PROTECT. can not clear data. how to solve it? thanks

check all the speakers connections for short circuits

unplug from wall
unplug all of the speakers and extra components and turn it on to see if the message disapears

if it does one by one start plugging that speakers back in
unplugging from the wall every time you add a speaker
(just in case the reciver only realises there is a problem after it shuts down)

if you find that after pluging in a speaker and when you turn it on check the wires for cuts or short circuits and check the speaker itself replace it with another and see what happens

That message means that you have a bad speaker or you have a bad amplifier IC most of the time. The amp circuit could have some other problem, but more times than not it is the amp IC.

How to check if it is the speakers or the amp circuit:

Unplug the speakers and turn it on. if you do not get the error message you have a bad speaker. If you do get the error message you have an internal amp problem. Then start plugging in speakers one at a time. If the unit turns on and stays on for a few minutes, turn it off and then plug in one more speaker. Keep doing this unit the unit gets the error message and when it gets that message you know that the last speaker you plugged in is the bad one.

Now the bad news

RCA no longer sells parts for their audio equipment. When the supply they have on hand right now is gone, thats it, no more RCA parts.

Now the good news.

The amp IC they use is a generic type that you may be able to get from another source.

But that is only good news if the amp IC is bad. It is the likely suspect, but without troubleshooting it on a test bench with the proper equipment, that can only be a good guess.

If you have found this help to you a good rating would be really appreciated.


check the speaker's connections, I got them message when a speaker wire was unplugged and plugged back in while the unit was powered on

RCA RT2250 Chck Speaker message

I have the same problem... I read that it can be a capacitor issue, they are on backwards. I just dropped mine off with the repair guy today... Does anyone know of a fix? Mine first had an electrical zap, then smoked, now CHCK SPEAKERS then off, and on standby...


If you have speaker wires that have strands, you may be getting a short if one small strand is shorting across the terminals, or a poor connection. Check carefully, perhaps even by disconnecting and reconnecting the wires. Also check for proper polarity - positive to positive, negative to negative. (unlikely since it just started). You can also get a new set of wires and check speakers one at a time to see if it goes away. or get another speaker that works and then replace each one with that speaker in turn to see if it resolves it. Good luck
