Question about JVC MX-D402T Shelf System

1 Answer

No stereo - one side only

One channel (left or right, I don't remember) of stereo suddenly stopped working. I recently had someone (try to) fix the situation. Now, one channel comes out both sides. (The repairer claims that he never new that something different was supposed to come out of the two sides.) Is it possible to get a schema that would help him figure out the problem? (I assume he just connected the left and right side together at the output.)

I want to connect my XL-DK255 to my TV (Sanyo DP26671). Please help!!!!
the only way to connect them is audio ...and you can either connect the Tv to the system ..(for better sound ) ..and in this case use the rca (left /right ) to rca (left right ) on the sharp ..if it supports..or ..use a double rca stereo cable ..with a jack 3.5 end ..and insert it in the audio input of teh sharp system ..
The signal from the Tv it will have to be taken from the audio out like in th epage 13 of the manual ..(it has a mono exit ..on rca probably ) and a left and right stereo one ..
If the sharp supports rca stereo in ...use it ..or ...just use the jack (3,5 stereo ) in ...and do not forget to select the proper channel ..
if the sharp system has a TV input channel for sound..on the receiver..use it ..and select the TV to playback the sound ..if it do not ..use the aux.. and selct the aux for control it ..
I do not believe you need to connect it in the other way cause it is not make any sense ..but the procedure is the same ..get audio signal from the system and insert into the audio in of the TV is in the same place and also available mono and stereo ..You will have to select the input in the tv menu..
The cable you need for a stereo connection I think will look like thi s..

Audio volume is weak from left channel but good from right. Problem appears to be after the amp stage as the problem still exists if i swap the audio in L to R. Also tried swappping the speakers and...

More likley that there is a fault in either the pre-amp or power amp of the left channel. To be honest with you it's one of the most diffcult problems you can have, unless you can see a burnt or damaged part. All you can do is compare the parts in the right channel with those in the left.
Touching the parts in either channel with a screwdriver (don't short any) will cause a buzz! This can be used to test the channels. Work backwards from the power amp section. Remember a buzz in the right should give you one in the same place on the left!
If you are not good with electronics consult someone who is.

Old Turntable Philips

You may have a bad stylus (needle), it can cause just that type of problem. Find a service center near you and see if they can get a replacement for you. They are very easy to replace, but very difficult to find.

Hope this helps.

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

Home stereos

Hi this is Compaqowner again NOTE: I know enough about home Stereos,and I am pretty sure to figure out 'power output' you take the total:in this case it takes in 110 watts total devide that by 2 so according to my math that is 55 watts (I guess this AKAI has a 55 watt amplifier) then you take the amplifier output (in his case 55 watts) and devide that by how many channels are being used,so in 5.1 DOLBY mode DVD movie,etc.(power to all 5 speakers) then it's 11 watts per channel,and in 2.1 stereo (power to the subwoofer,front right,and front left speakers only) it jumps up to a little over 18 watts per channel,again,I think?,when you find the answer,please let me know. Thank you for your time. Steve B.
