Question about JVC HX-Z3 CD Shelf System

Open Question

High frequencies On my JVC HX-Z3, when playing CD (no matter audio or mp3) in surround modes (Dance, Hall, Stadium), the high frequencies from time to time just goes louder, without doing anything.The sound just changes by itself! I noticed that 1min & 40secs the sound is normal, then the next 1min & 40secs are with boosted high frequencies. When in Rock, Pop or Classic EQ there isn't such a problem. This happens ONLY when playing CD in surround modes(and most noticeable in Stadium).

SOURCE: mx-d402t jvc cd player - trays will not open

Just got one of these at the dump. Two problems quickly jumped out at me:

1. As mentioned above, the CD trays stuttered and clattered but would not open.
2. Volume control is unable to be reduced from the highest level (50).

CD tray table was an easy fix.

After removing the 8 cover screws (6 on the back and 2 on the sides) and the 6 tray mounting screws (two through the back and one in each corner) I unplugged the only electrical connector - it is a simple push in pull out type. Note the way it plugs in before pulling out - it doesn't matter which end which you unplug. I set the entire changing assembly aside (outside the tower) on a speaker - just for height because the cable is fairly short. Then hooked the electrical strip back up and turned the power on to the main unit. After setting the controls to CD and pushing the eject button for tray #1 it only took a gentle nudge of the linkage to allow the entire stack to free up. Cycled through the trays several times and each slip in and out as designed.

The next step is not for the faint of heart. Since something (in this case just some cat hair and normal 10 years of dust) was causing the trays to stick it was decided that the entire unit should be thoroughly cleaned. With most electronic devices as long as there is no power on the component it is perfectly okay to wash the entire unit with hot (really hot) water from your kitchen sink. A soft tooth brush and some liquid detergent help the process. After a good long wash and rinse, gently shake as much excess water from the piece and find a supply of warm flowing air. Set the component in front of the air supply and allow it to dry for a looong looong time. 3-4 hours is good.

Hook it back up, cycle the trays and observe the function, paying special attention to where the moving parts make contact. Then shut it down (or not depending on your confidence in your hands) and apply some WD-40 to a q-tip. Using the swab apply a small (the key word is small - you do not want oil based liquids to get anywhere near the CD reading LED) amount of lubricant to the previously observed bearing points. This procedure is best accomplished as the linkages are moving throughout their entire stroke but be careful to not catch the swab in the moving parts.

Now (while I wait for my C changer to dry out), I will trouble shoot the volume problem. If it is something that can be fixed, I will update this post. Please don't assume that just because something has some years on it that one should "expect" it to fail. Oftentimes it just needssome TLC.

Compact disc and DVD players use a laser pickup and the older analogue systems such as records used direct contact such as tape heads and phono cartridges/stylus which were essentially the pickup units for these items.The pickup unit for a CD player is simply the laser assembly that reads the digital information from the dics..I hope this was helpful.....Peace....

Unit powers up, cd and radio seem to be operating properly, but no sound is heard, unit worked fine a few days before, all wires are conected, everything seems unchanged you said...the unit powers you don't have a "dead set".I don't know if the speaker can be disconnected from the unit.As a rule of is very rare that both channels (left and right )fail at the same is usually one channel while the other speaker still operates.This is what I want you to do...In a quiet room..get really close to the unit...Switch it on and listen for any sound from the speakers...get really should hear a slight hum from the woofers and a high frequency "hiss" from the tweeters....If no sound is heard..switch the unit off..You should hear a "plip" sound...If not...switch it on should hear a slight "bump" sound from the woofers...If you hear no sound from the speakers at all..there is a problem with the output stages of the amplifier section.If you do hear sounds fron the speakers,,Turn up the volume and watch for an increase visually on the display (such as ascending numbers).If there is no indication of a volume increase...The "mute" may be stuck on..Try switching it off and on...please let me know what happens after you do all the tests....Looking to hear from you......PEACE!!!

JVC HX-C6 goes directly into "Protect Mode".

I received a reply promptly from JVC to check power connections for shorts. O course I had already done that. So as a last resort, I pushed the power switch on and held it for maybe 10 seconds. It seems to have reset the unit, and it's playing fine. Best of luck, hope you all read this and it works for y'all. AJ
