I'd say the cartridge is getting tired. Swap the head shells with carts and test. Cheers john. Styluscity

SOURCE: SL1200 MK5 NO SOUND FROM RIGHT CHANNEL

Issue is either your tonearm or your RCA cables. Unfortunately, there is no easy way to determine which is the problem. I would suggest replacing the RCA cables first, as it is the least expensive. If it does not solve your problem, then the issue is with the tonearm.

You can also do this for now:
Remove your headshell/cartridge from the tonearm. Look inside the tonearm tube, you'll see 4 gold prongs. Make sure all 4 prongs are protruding, and are 'shiny'. If they are not, then the issue is with your tonearm. If they look good, then more than likely, the issue is with your RCA cables. Taking it to a qualified repair center will help in determining what is the issue, but they will need to open your unit to test, so be prepared to pay for the estimate right off the bat.

If your in the NY Metro area, look us up. We also offer nationwide service, if you cannot find anyone local:

SOURCE: No signal from the Left output + Tinny sound

1. Assuming there is no problem with your amplifier of input cable, the headshell/tone-arm needs rewiring. This is very thin flexible wire and not easy to do, but can be done if you are careful.

2. Turntables require a special input on your amplifier which has a frequency response that is suitable for them. If you connect a turntable to an ordinary input, it will sound tinny. If you don't have a turntable input (known as a phono input [from phonograph]) you will need to use a preamplifier with your turntable.

SOURCE: no sound out of deck

If you've already replaced the RCA /Phono cables, then the only other item that would cause this kind of problem is your tonearm, and it will need to be replaced.

SOURCE: Dj decks-no sound

You didn't state if you purchased this used or new. If used, maybe the tonearm or the rca cables are bad. Or, if you set it up inccorectly.

Just to be sure...

TURNTABLE -> MIXER PHONO INPUT (CH1 or CH2) -> OUTPUT MIXER (MAIN OUT) -> STEREO INPUT (AUX IN or LINE IN).

Make sure you have the line selected properly on your receiver, and if you have a tape function, press the button in and out. Sometimes this will affect the sound. Now, check to see if your getting any signal to your mixer. Make sure the toggle switch on your mixer is set for PHONO and not LINE. Raise all volumes, including heapdhone, and see if you hear or see anything on the levels.

If all is good, but no signal going to mixer, then you might have a bad tonearm or RCA cables....

To check, disconnect the cartridge/headshell from your tonearm. Look inside the tonearm, and you'll see 4 gold plated prongs. Make sure they are all evenly protruding. Also make sure they are all a shiny. If you see any black substance on any of the prongs, they need to be cleaned. If any look like they are stuck, and not sticking out like the other ones, this would also cause an issue. This cannot be repaired. You can try to get the prong to come out, but if it does not work, you will have to replace the tonearm.

If everything with the tonearm looks good, then the issue might be the RCA cables. There is no easy way to check this, other than opening up the turntable. This is not easy, and I do not recommend.

Let me know how it turns out.

SOURCE: 1 X 1200Mk2deck higher volume / causing spkr not to work..

Problem If you swapped the two TT's would the problem stay with the connection on your mixer? At least then you/we would know wherein lies the problem. I'm betting thge low volume is because you have the phono jacked into a line level input like AUX instead of PHONO.

Typically, what you're describing is a phone source plugged into a NON-phono connection. (Tinny, low volume - classic lack of a phono preamplifier with RIAA equaliztion). A standard old-school tuntable requires a phono preamp that is labeled "PHONO". Nothing else will give it the boost and freq response correction LP's and phono cartridges produce.

Your problem #2 alludes to a channel problem with a turntable running through your mixer. This isn't rocket science. Swapping the two turntable channels around would probably change the apparent failing channel, right? Yes - Problem out at the turntable. No - problem in the mixer. You've already hinted at the source by monkeying with the tonearm wiring. You're on the right track. The tiny multi-colored wires in the cartridge shell are very thin and delicate. Their brass fittings sometimes oxidize and reseating them as you have done usually gives some relief. Kinks in the wires could cause your intermittent symptom. At the RCA end of the tonearm cables, make sure they're seated on with a twist to wipe off oxide.

Problem #3. Is it just bothering you or is there a functional problem, too?

When playing LP the sound is bass heavy, but when playing a cd, the sound is perfect.... any suggestions?


The record deck is played through a separate pre-amp to all other functions, so it therefore could be a fault in that pre-amp, but I doubt it. You can fit a wide verity of cartridges in record decks that will each give a different response to the sound. But first check that the cartridge connections are correct. Try swapping them around, it might change what you get. But it could simply be that you have a cartridge that produces a lot of bass. Changing the cartridge to a high quality recommended type - by say some hi-fi buffs website or magazine, might solve the problem.

DP29F turntable has static


either you haven't earthed the deck to the amp, on the proper ground screw, or your head shell wires are touching.
if the cartage(the thing the needle slots into) unscrews from the tone-arm, try unscrewing it,then putting back on, nice & tight....
if it still does it then it's your RCA leads that go from the deck to the amp(phono cables).
normally you would wire a deck/decks to a mixer first, then from the master out on the mixer to the AUX IN on the amp.

Husky yth1542xp. I've changed the blades, leveled


When levelling the deck, rotate the blades so that the right blade has one of its cutting edges at or near the right side center of the deck. Do the opposite with the left. Measure to the blades from the level ground, not to the deck. Try leveling that way.

No sound from left speaker on right deck. left deck is fine. confused! tried unplugging one at a time and only the right plug is working. is there anything simple i can do to rectify this problem? as...


To find out what the problem is try this, swap over the right and left leads from the deck to the amp. If the problem stays on the left channel there's something wrong with pre-amp in your amp. If it goes to the other channel (right dead) it's the deck. Next remove the wires to the cartridge to the deck with the fault. Make a note of how they fit on the cartridge before you do. With the amp connected to the deck and on. Touch (one at a time) each of the four wires with your finger. Two of them will probably produce no sound. But from one wire you should hear a buzz on the left channel and from another wire a buzz on the Right channel. If you get a Buzz on the left speaker then all the connects are good and the cartridge has gone. If you don't get a buzz, then there is something wrong with the left cable connector between the deck and amp.

All is fine with this turntable eccept for the fact that when the sound comes through the speakers you can make out the track but the sound is distorted.


Hello
You don't say whether you have only just acquired this deck or if you have been using it for some time and it has only now started to give problems.
There are 2 or 3 possible explanations.
  1. If you have only just got this deck and are using it on a stereo that has a dedicated phono (record player) input it may be that you need to get inside your turntable to turn off the built in pre-amplifier switch. To do so make sure the tone arm is securely fixed into it's holder (a rubber band will hold it in tightly) before turning the deck upside down and unscrewing the bottom.
  2. If you have just got this deck and are trying to play it through a stereo system that does NOT have a dedicated phono (record player) input you may need to get inside the deck to turn the phono pre-amplifier switch on.
  3. And if the deck has been used for some time this is the most likely - the record stylus (needle) probably needs replacing. Personally, although it is a bit more expensive, I prefer to replace the whole cartridge rather than just the stylus as they do need changing from time to time anyway. Always replace the stylus at least at the frequency recommended by the manufacturer. Regularly clean the stylus with very gentle strokes from the back towards the front using a small soft brush.

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.

Muffled sound


HELLO!
I don't think the problem is the actual stylus (needle), it sounds like the magnetic cartridge has become faulty in some way (it does happen). My advice is try another cartridge and stylus (borrow if you can). If the audio stays the same then it MAY be the wiring in the arm going through the plinth (deck) and these wires terminate to pins or a small pcb board in the turntable where the phono cables and arm wires are connected. There may be a bad connection inside.
Also, make sure your tonearm counterweight and anti-skate are set up properly as well as this can have an effect on audio.
I hope this helps as I have been into audio since I was a kid!
