When watching DVDs/ music the sound randomly cuts out. This mainly happens when the sound is pretty loud. Ive talked to a few people about it and they say that it sounds like the amp has blown. Is their anyway to fix this or would I have to buy a new amp for it. If so how much do they roughly cost.
The system seems to work fine but through a film the sound just goes dead. Any help would be appreciated.

Re: Sound cuts out
If you listen to cd's and the sound dos'ent cut out then it cant be the amp. It could be the audio cables are intermittant between the amp and the dvd playerr or they are loose or corroded a little. or ppossible the input your using is going bad on the stereo sytem but I wouldnt think that the whole system was blown if the radio and the cd plays normal.. check out the causes I listed and let us know if you need more assistance\..:)

OK, this is just a suggestion, without analysing the unit myself.
From my experience with these type of units, it is usually overheating of the IC's on the circuit board. You can do another test just to double check. Turn the unit off, unplug it from the wall supply for about 10 minutes. Then plug the unit back in and turn it on. Now turn the volume very high, without the speakers starting to distorted, where you can still hear a clear sound.
Now, if this is an IC overheating, the sound should start distorting and cutting out. This is actually a very common occurrence with these types of players as well as receivers in general.
Try the above, let me know what happens.
Also, please do not hesitate to let me know if you need any further assistance.
Darren Kelly-themasterofthrowdown...I've had mine since they came out in 1985. Here's what you do...Each of the 4 channels on the upper right function as an individual equalizer. You set each channel one at a time. So, you have the ability to change channels on your e.q. without resetting your faders(you just push ch. 1 2 3 or 4) and the sound of the music will change according to how you set ch 1 2 3 or 4)DON'T UNPLUG THE SH-8046 WHILE THE MUSIC IS PLAYING OR YOU WILL LOSE YOUR CHANNEL SETTINGS -ALL YOU BLUE LINES WILL END UP STRAIGHT ACROSS AND YOU'LL HAVE TO RESET THE 4 PROGRAMS (AGAIN) you don't have to set all of them*--Now, you set them with your finger (sweeping it up and down on the touch-screen (REMEMBER TO PUSH THE (LOCK) BUTTON FIRST)you have to unlockit it...then you have the ability to adjust you frequencies(the blue lines)once you have a good sound, YOU PUSH A NUMBER...say, 1...then push MEMORY then push 1 again...AND CHANNEL 1 will be set ---do the same thing for the other channels --IF YOU PUSH THE L or R button you can set the E.Q. channels different from each other (if desired --it's just an extra function...and both settings will appear on the screen. But I just keep mine both the same(Left and Right). When you record music(like I do - being a Musician) it is important to be able to listen to the play-back-SO YOU HAVE TO PLUG THE CD RECORDER BACK IN TO (PLAYBACK ON THE REAR OF THE sh-8046-(PUSH (TAPE) TO LISTEN TO YOUR TAPE RECORDERorCD RECORDER)to hear what you recrding sounds like.PUSH -SOURCE- TO GO BACK TO REGULAR PLAY MODE---If you ever walk in and cut you system on and nothing happens, check to see if on SOURCE or TAPE-(rec eq) on the bottom right is supposed to make the music sound better,push it to cut it on/off when you make tapes/CD's the red light should cut on ...Reverse --flips your EQ settings upside down(not such a useful function)....I guess that's all I can tell you, this is the only EQ I need for my overall system and I haven't bought another one for the mixer. IT HAS NEVER MALFUNCTIONED IN 25 YEARS -- I'M USING IT RIGHT NOW FOR MAKING PROFESSIONAL SOUND QUALITY CD's. SO HAVE FUN! Darren Kelly- firstname.lastname@example.org
Sounds like an amplifer fault. Many of these Midi system use a large black IC attached to a metal heatsink. They control both the power amp and pre amp on both channels. When they go wrong they can cause all sorts of effects,
If you can repair things I would look at that. If not get ready for a large bill. If it's the IC some are expensive, it does most of the work!
This sounds like a power disconnection problem.
you have a large amount of components, on the motherboard that charge up with being used. ( namely fets/capacitors et,c ) when your system is powering off the instant disconnection of mains power, can cause a Bang or Pop to the speakers.
I,d suggest trying swapping the speakers over from right to left and vice versa. see if the errors still there.
Also try turning the volume right the way down, before switching off. is the bang quieter ?
Check the mains cable ( plug end ) see if theres a broken or loose wire at the plu ( causing an arc ) finally check that the plug ( cable grip ) plastic tang that holds the cable, has,nt been overtightened and damaged the cable underneath it.
I hope any of this helps you to a self diagnostic rectification of the problem listed. Also try without speakers is a suggestion.
Mike @ Compurepair.
use the speakers it came with it works fine for me i have mine hooked up to a 300w inverter anything less i dont get the best sound you cant turn the volume up too loud on the reciever it will draw too much power and shut it off or blow the fuse in you car unless the inverter you are using has an external fuse on it my inverter warns me that i am drawing to much power so when i hear the beep i turn it down a notch and works fine but ya try using the speakers th system came with
The unit probably has resistors or a limitor curcuit to limit the amount of audiop going out on the headphones. It could probably be modifyed but it would possiblt burn out the headphones as this is a 280watt peak power unit . Its there so you dont blow out your ears.you could use some wireless self powered headphones as that would solve your problem!! Good Luck
there are 2 options for this:
1) if its a anlog knob then the AMP inside is gone bad...
2) if its a digital knob then it is preesed constantly
and there for raising the volume level
try disassemble the system and making the spring knob more efective
