Trying to rewire cartridge

When removing Quasar CS 7400 cartridge the four wires came off the solderless connections. I lost my notes and cannot figure out what colored wire goes where on the four prongs. The colors are red. white. blue and green. I just bought the replascement needle 710/D7.

Bottom Two-> || || 3 & 4

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 have an electro brand 9249 record player. How do I remove the needle and where do I get a new needle

The needle and cartridge can be bought from most of the standard electronic sparepart selleing shops at your town. It will be best to replace the cartridge along with needle. Cartridge will have a number printed on it, should be noted. OK.

There is no sound in the left speaker when i play LP's. When i play CD's and the radio both speakers work, but when i play records sound only comes out of the right speaker. What's up with that?

Two possible reasons. First a faulty cartridge. With the amp on the phono setting, lift the arm up and you should see wires coming out of the cartridge. Make a note of how they fit or remove them from it one at a time. With your finger touching each wire, you should hear a buzz on at least two of the wires (one on the left and one on the right). If you do then the cartridge has gone! If you still don't get a buzz on the left, then the cartridge pre-amp has failed. Most likely an IC.

Hum form both speakers, and moving the speaker cable where it goes into the console starts/reduces/stops the hum. Any solutions out there? Is there a ground wire broken in the connector?

Had this problem for years with my much loved SS5. Only just now i decided to pull it out and fiddle with it some more and have the "humming problem" SOLVED. See description and PICTURES below

-remove the 2 small philips head screws from the speaker plug.
-first note which wires go where, i took a picture.
-take a small object to "lever" up the tiny plastic "fingers" that hold the plug wires in the plug housing, i used a small file, but you can try fine nosed tweezers.
-whilst doing this pull back at the wire at the same time to remove the metal terminal from plastic housing.
-repeat for the remaining wires.

i used small electrical snips to "pinch" the tiny metal plugs to make the connection tighter. I pinched it till there was almost no space between the contacts then re-insert wires till it clicks and it is then locked in place.

replace the housing with the 2 screws, and when you go to plug the speaker back in you will feel it is "tighter". No more humming at all!

-repeat for other speaker. The process of "pinching" may take some practice to get it to fit nice and snug around the connecting pins in the SS5 main unit.

Note; pinch from the bottom flat surface of the metal, and you will see the contact coming closer together. if you do it from the top, it will simply spring back open when you release the pressure.

hope this helps, this problem had me scratching my head for a long time, i even tried re-wiring the plug, when it was simply the metal pins in the housing!

First check all back of amp speaker connections !Look for stray wires touching metal or other contacts (make sure amp is off) this is the main cause of this !( once rewired turn on!) this should fix ya!

Faulty sterio

The fuse is usually right, and preventing a fire and worse. If you connected your speakers reasonably (do check it; perhaps someone else has issues with your tastes and rewired them) and it draws more than 5W when run quiet (try a Watt-Mizer or such unit to check it) then either it was made very badly or the dust in your house is made of metals (you would know!)
You could test it with the speakers disconnected and volume down to test that first, if you like. Connect one and see how that goes, then the other. It's certainly possible they wired a speaker sloppily inside, and/or advised you to stick wires in too far, but it would make little sound (due to the short).... Sound is very low-power and doesn't take 2000W unless you want to emulate a 50x scale cello or 1/1000 scale jet.

Low Volume from right speaker of entertainment center - turntable only

Hi There thanks for your very good desctiption of the problem it really helps to have a lot of detail...

There are Mono and stereo types of stylis cartridges and it sounds like you have a mono equipped into a stereo amplifier..

If there are 4 small coloured wires visible under the stylis then
its a stereo stylis and should work, have a close look and maybe one of the small wires has dropped of the small pins on the back opf the stylis cartridge.

If there only two wires visible then its a mono cartridge and this is why you only have sound from one channel..

So answer is wires dropped of the stylis.
Wrong type of stylis cartridge.
if there are four wires and thay all look connected then perhaps the stylis is faulty and you need to replace it...

Cheers from YU BEUT
