Re: error message

If the "check speaker" is always turning on, it is possible the amp itself is shorted at the IC. Replace AMP IC pack or if it has N and P channel output transistors acheck them. Some amps do use a thermister and this could be burned open in circuit.

Cant increase volume. Shuts down and says checking audio

Try disconnecting all speaker wires from the back of the unit. If it still shuts down, then you need to take it in for repairs. If not, then you have a shorted speaker or wire.

Having a problem with my Thomson DPL 550HT home theater. When i try to play something the sound repeatedly goes off and on in about a one second interval.

I would have to guess that the internal power supply has one or more bad capacitors. Time to take into a technician for repairs.

Maybe you should try to find Navilight Universal Remote Control?
Thomson uses them.

Error message "Protect"

you can try to hold the stop button down for 5 seconds while the power is off to reset. If that doesn't work disconnect all the cables from the back expect the speaker cables and the power cable. then turn the unit on and reconnect the cables once the unit is on.

Cannot read Xvid ... does exist a firmware upgrade

No. you will need to convert this format to a recognizable format that is compatible to this particular unit. there is not a firmware upgrade that will assist at this time.

Lifestyle 30. sound stops, i unplug and plug back in and works for short time and quits. unpllug and plug back and works a short time and quits.

What you describe, sounds like a speaker short. Are you using the Bose wiring with their ends and no cuts in the wire? (splices) It's not too uncommon to extend or shorten a wire. The fastest way to find a short is to disconnect your speakers at the speaker. Be careful to keep the wires separate if they are not on plugs and turn on. If it cuts off (power) or says (protection) on the display that lets you know your speakers are ok and you have a short in the system or a wire. Next, disconnect wires at the sub one by one and test until it causes the system to cut off or short. Leave that speaker disconnected from the sub and test with all others connected. Now you've located the channel that has the problem. First just connect the wire again to the sub. if it cuts out, run a new wire from the sub to the spkr, for testing purposes make it a short wire if possible and test. If you need to use a Bose plug at the sub to test spkrs go buy one at Bose, don't cut your factory wire just yet. If a new plug works then cut and replace. Make sure you use electrical tape not scotch tape or duct tape. If it works fine, test the new plug on the old wire and see if it works. If it does your done, if it doesn't, run a new wire to the speaker with the new plug on it. If after all this and it still doesn't work. Sounds confusing I know, It's just process of elimination, that's how we do it in the field. If all your speakers are disconnected and it still cuts out, it could be the sub or the receiver. Take it to a Bose store and they can check each piece for functionality. If it needs repaired let Bose do it. Hope this helps.

RCA rt2500 "CHK SPKR" comes on when i turn it on.

"CHK SPKR" Check Speakers. Remove all speaker wires and turn on receiver. If it still says check speakers, you have an amp that needs output transistors or possibly just soldering of an emitter resistor but thats rare.

Chk spkr

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.

Chk spkr error message

Your problem is the output IC's The case where you say the speakers buzz tells you theres a short in the audio outputs. If your unit didnt shut off, the speakers would fry and the unit would also smoke. These are solid state devices and are soldered in, and are not concidered user serviceable parts, unless you know how to solder and trouble shoot Stereo systems. This is a job for the pro if you want it fixed. Good Luck

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
