My Harke LH1000 always stop producing sound from it's speaker after playing for some period, what is the issue please?
The Harke LH1000 stop producing sound after playing for sometime
When this happens, the Amp still produces sound from the house but just not from the connected speaker
any i dea of the cause and how to resolve will be appreciated
Re: my Harke LH1000 always stop producing sound from it's...
There could be a few potential issues that could cause your Hartke LH1000 amplifier to stop producing sound from its speaker. Here are some potential causes to consider:
Overheating: One possible cause of this issue is that the amplifier is overheating. This can occur if the amplifier is being used at high volumes for an extended period, or if it is being used in a hot environment. When the amplifier overheats, it may automatically shut off to prevent damage to its internal components. To prevent overheating, make sure that the amplifier is well-ventilated and not covered by any objects.
Speaker Wiring: Another potential cause of this issue is faulty wiring between the amplifier and the speaker. If the wiring is loose or damaged, it can cause intermittent sound or complete loss of sound. To check for wiring issues, inspect the connections between the amplifier and speaker to ensure they are secure and free from damage.
Amplifier Faults: If the above causes have been ruled out, then there may be a fault with the amplifier itself. This could be a problem with the power supply, the output circuitry, or other internal components. In this case, it is recommended to take the amplifier to a qualified technician for repair.
Protective Circuits: Some amplifiers have built-in protective circuits that can shut off the amplifier if it detects a problem. This could be caused by a short circuit, a speaker impedance mismatch, or other issues. Check the amplifier manual to see if it has any protective circuits and what they do.
If you are unsure how to proceed or are not comfortable troubleshooting the amplifier yourself, it is recommended to take it to a qualified technician for repair.

If the fuse is correct ( check manual) it shouldn't blow under normal operation. Once in while a fuse will break internally and thus blow the fuse. look close at the blown fuse If it is a "violent" blow (totally black inside) then you have an overload condition. I would use an ohm meter to check the connection to the speakers. Usually it should be between 8 ohms and 4 ohms if the number is lower than 4 ohms your speakers or wiring are putting to much of a load on the amp. If the fuse was not a "violent" blown fuse then replace with a new fuse of the exact proper value. many amps use an MDL fuse that is a slow blow fuse and has much different in circuit function than a ACG fuse so use only the exact proper furse that the manufacture recomends. If the load (speaker and wiring) is correct and the fuse is correct and still blows then you have a component problem and the amp will need repair
Intermittent problems are always the hardest to diagnose but I would start by going to the device manager and deleting the sound drivers. Then a reboot and as your machine restarts it will reinstall the soundcard drivers and if the game has corrupted the drivers that should your your problem. Should it continue you will need to find updated drivers for Windows 7.
having same problem with Mpeg files have no sound when played in power producer gold. I notice that SW Synth, CD Audio and PC Speaker is always muted when capturing from Camcorder camera. Any suggestions. Also no sound when played with media player.
Hi when using surround sound its important to understand that not all soundtracks have a "rear channel' meaning that the rear speakers will not always produce sound. In fact the rear channels may only produce sound about 10% of the time.
Your receiver has a "test tone" which sends a tone sound through the 5 speakers you should turn the speakers up or down so that all 5 speakers produce about the same volume.
The speakers of course will have a different sound to them depending on the brand and model but just try to balance it as much as possible.
Should also point out that you need to start out with at minimum a STEREO signal and that it needs to be connected with good quality cables. If possible use the optical inputs or HDMI which is a digital signal but not all receivers have that capability.
Lastly play around with the settings Dolby is of course the standard but many receivers have Neo or other proprietary surround formats which may produce the desired effect.
if you have used the same cable to plug it in a different port, then i would say it is not the cable. it's more of a port issue or it's just that the sound card does not send a signal to that channel anymore. try using your unit on other sound systems and see if you get the same result. or you can set your pc to run on 2 channel mode only to test if the two speakers (L front and L rear, in this example) can produce the sound on the left channel (you do the same for the right, obvioulsy). if that still exibits the same symptoms, then it is definitely a port issue.
I had the same problem: speakers worked, but clicked whenever they were on. They are actually Compaq speakers connected to a Dell computer. I solved the problem by moving the speakers about 12 inches farther away from my wireless router. Very easy!
It is not an issue with the speakers or the sound card as you get sound in media player and also while playing cd's.
It could be the volume settings on the player tht the websites use to play the audio or the video,
