Also at high volume you may be getting feed back caused by vibrations from the speakers through the decks

Those are just standard phonograph player characteristics in my experience. You'll hear a tap on the deck because there's essentially a live mic ( the needle ) physically coupled with the record on the turntable and the rest of the phonograph player even though they try to dampen the coupling of the turntable as much as possible. The rumbling noise at high gain is because the turntables being driven by a motor via gears or a belt and creates some  vibration, wich is transmitted through the turntable and picked up by the transducer ( needle ), low frequency rumble, just like a recording studio on a busy street may pick up from road vibration/ noise.

Sony stacking system LBTd505, the sound from the record deck suddenly went very faint. The cd and radio sections are fine. I have tried a new stylus, but no difference. Any ideas?


You have two options. First a faulty cartridge. Or a faulty pre-amp in the main amp.
You can find out if the cartridge (and amp) are playing up. By removing the connectors on the cartridge.
Then with the volume turned up to about half, with your finger, touch each one of the wires one at a time. It will not harm you at all. But you should hear a loud buzz on one wire on the right and a loud buzz on the left on another wire.
The two other wires will either produce a crackle, or a tiny buzz, or nothing at all.
If you do hear a loud buzz on two wires. The cartridge is faulty and needs replacing.
If you hear a slight buzz on them or weak sound. There is either a bad connection between the deck and amp. Or the pre-amp inside the deck which is only used by the record deck so will not effect any other function, is faulty.
You can remove the record deck connections to the amp and again with the amp on half full, touch the inputs with your finger. If you are not hearing a loud hum or buzz, the pre-amp is faulty. If you do the connectors are faulty.

I got a problem with my decks, One deck, when i put the needle on it, the needle would play a bit then just slide across the record a bit then play a bit or if it did not do that it would keep on jumping....


It does sound to be a tone arm balance and /or anti skate issue - I found some great solutions online which describe it much better than I can so look at this clip which may help you ... I don't know what to suggest about the stuck one - here is one clip that is really helpful - and youtube usually shows you others - or key in tone arm balance into search engine https://www.youtube.com/watch?v=rxyuZ4073po

Im having kenwood home stereo system model no xd-v818 ...in high volume about 80 the sound starts to distoriate and the voice is not clear..i want to kno wether the stereo deck is not able to provide...


Well, here is the situation as I understand it. Here is also some theory to help you out.
Your Receiver or Amplifier has a "scale" showing relative volume. Distortion always increases in speakers and amplifiers when you turn them up. If the sound is getting extremely distorted, the Receiver is attempting to operate above it's maximum output. The scale is an average, but because music recordings are often mastered at different levels, "80" may be too much. When an amplifier section of a receiver is over driven, the distortion (which you observed) will damage or burn out your speakers. Most likely the tweeter (high frequency speaker)
If you back off the volume, or turn down the output of the deck until the sound becomes clear, then that level, IS FULL VOLUME. Based on what you are saying to me, I don't think anything needs service.
There is one other very important thing I should mention to you
. When people use high powered equipment and initially turn up the sound. After a short time, the mind turns it down. What next happens is the reason professional musicians and sound engineers often have permanent hearing loss after a relatively short time.
What happens is that the listener and often the engineer running the sound board at a concert thinks the sound is not loud enough (when the audience is happy with the level) and turns it up. After turning it up, his mind (and the audiences') turns it down and then he thinks it not loud and then again turns it up. And up. And up. The only reason I'm not deaf is that I discovered this when I was building sound systems as a kid. I also studied about it. So please be careful when you play things loud. Permanent hearing loss starts to occur at the very high frequencies and rolls down from there over a period of time. Hearing loss can start to occur in just a few hours.
at 110 decibels. It doesn't come back. If you understand this, you'll keep your hearing.
I hope this helps,
Best Regards,
Mark

1210 mk5 poor sound


If the cartridge is good and your wiring is good. Then it's either got to be a fault on your amp, or there is a pre-amp in the deck itself faulty. Double check that the amp is working, amps have a pre-amp for record decks, they cause trouble a lot.
If you touch the wires that connect to the cartridge, you should get a buzz on either channel (remove them from the cartridge first). If you don't get a decent buzz, and you know that the amp is working fine, then there's something inside the deck causing the problem. In which case take the bottom off and take a look inside.

No Bass


Try turning the volume up on your laptop up to high, while the volume on your deck is lower... This will put a stronger signal into the deck first... you may get more bass, Another trick is to EQ the highs and mids lower and crank up the bass... see if you get an acceptable amount of bass with these tricks..

1210 internal fuse keeps blowing


First and foremost, the tonearm has absolutely NOTHING to do with the power. They are not connected in anyway. The only thing that links them is the tonearm is grounded to the chassis of the turntable. Nothing else. However, this will not cause this sort of problem.

Turn on your turntable without using the POP-UP light - keep the light down/off. Try it then. If it works, than the issue is there. If you still have the same problem, then the issue is something on the main drive circuit board which is overheating, and the fuse is going to protect the unit from any damage. Take a look at R213 - see if it's burnt around it's area. If so, more than likely this is the culprit.

This is not an easy diagnosis. Highly recommend taking it to a service center.

Technics 1210 feedback/grounding problem


Since you've already replaced your RCA cables, and tried different cartridges, the only other thing that would cause this type of issue is your tonearm. It's probably on it's way out, and will need to be replaced shortly.

You can obtain a replacement tonearm HERE, however, it's rather difficult to replace the tonearm without experience or knowledge on soldering.

Good luck!
