Top 20 JVC MX-D301T Shelf System Questions & Answers

The volume is probably controlled by an IC that does all the work. It most likely has failed. It's unlikely that the wheel is the cause of the trouble, unless it has broken leaving the circuit fully open. But I think that unlikely. If the unit has not been used for sometime then the second fault will probably due to the belts turning to goo!

Any audio device that has a headphone output can be adapted to feed an RCA cable pair for standard stereo to any audio device with a standard RCA input (except one labeled "PHONO"). Get a cable like the one described here: http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10218&cs_id=1021804&p_id=665&seq=1&format=2
and connect it into any available analog input on ANY audio device EXCEPT one labeled "Phono".

Hi, I just set the time on my mx-d301t and it goes like this: First you need to put the device to standby mode (red light and the time are showing). Then you take the remote and press first SHIFT button and then CLOCK button (number 1) one after another and the time should start blinking. Next you can set the time by using the SELECT buttons - (number 4) and + (number 5). When the time is right you just need to press SET button (number 8) and the time should stop blinking. There you go, the time is set. -amigo

do you want the value of that resistor?

can you see the colour bands on the resistor?
there could be 4, 5 or 6 colours on it

if you can tell me the colours in order

There are rubber drive parts used in the cassette mechanism, and over time they wear out. Infrequent use can hasten the rubber failure (similar to how a car's tires can go bad if a car sits idle for a long time). An overhaul by a stereo service shop, a good cleaning and replacement of the affected parts, will bring it back to life.

Dear friends, i speak of Brazil/São Paulo, i already repaired this excellent systemnJVC, i sought you and found the manual for this device; but i'm looking for the remote control because my does not work correctly.

Check if there is something jammed in your tray.Or it might be the wheels that might have gone unfunctional.
There is a small hole on the tray where you can stick a pin or something small to eject.It might only be once that this problem is happening.So try it.

First, and the best choice really, is to take it in for servicing. Second, is to remove the chassis and try to determine if you've just got a disc that's jammed the mechanism. If so, remove it and replace the chassis and see if operation goes back to normal. If it doesn't then there's a problem with the motor which opens the tray and you'd have to take it in for servicing at that point.

You can take a dry q-tip and clean off the lens of the laser assy. This is all that a consumer can do. Otherwise take it to a repair shop.

well..that looks to be a clear indication that you have a lens cleaning challenge. Believe it or not, it 's not unlike the old head cleaning for audio and video players. Now, here's the rub, the cleaning kits that are recommended are quite dear. Let me see which ones are available for this unit.

Silmilar problem on a MX-D501T
At times the unit fails to recognise the music CD in the tray, or recognises its presence and shows tracks & time play on screen but doesn't initiate playing. The fault is erratic. Pushing 'play' on the remote doesn't initiate either.
Is this a faulty head or 'dry joints' somwhere?

Here is the user manual; https://www.manualslib.com/products/Jvc-Th-A75r-252593.html

The sound you're hearing could be due to a variety of reasons, such as a loose connection, a malfunctioning component, or a power issue. Here are some steps you can take to troubleshoot the issue: Check the speaker connections: Ensure that the speaker wires are properly connected to the receiver and the speakers. Make sure that the positive and negative terminals are correctly aligned. You can also try disconnecting and reconnecting the wires to ensure a secure connection. Check the power source: Ensure that the receiver is plugged into a working power outlet and that the power cord is securely connected to the receiver. You can also try plugging the receiver into a different power outlet to see if that resolves the issue. Check the volume level: Ensure that the volume level on the receiver is not set too high. High volume levels can cause distortion and other issues. Reset the receiver: Try resetting the receiver to its default settings. To do this, turn off the receiver and unplug it from the power source. Wait for a few minutes, then plug the receiver back in and turn it on. If these suggestion don't help, you may have to seek professional repair.

A bit of basic knowledge is required first; Insert CD, the first thing the processor expects is to scheive Focus. When Focus is acheived, the Spindle Motor will turn. Either the Laser cannot Focus or there is an issues with the Spindle Motor. Which is it ... if you know, then you will know which part or board has the issue.

Question edited for clarity, toss in some CAPS, add the Magic word. Strangely there is no owners manual but there is a Service Manual for it. It appears that it is actually a 'JVC FS-2000GD'? Normally turning off the alarm just requires pressing the Alarm Set button one more time to toggle it off. Or you can disconnect it from the mains, remove any back up batteries if it has them and it will reset everything. Then set the time.

If your JVC E100SL receiver is showing an "Auto Mute" message and you are unable to perform a factory reset successfully, there are a few troubleshooting steps you can try to resolve the issue:

1. Check speaker connections: Ensure that all speaker wires are securely connected to the receiver and the speakers. Loose or disconnected speaker wires can trigger the auto mute feature as a safety measure.
2. Check the speaker impedance: Verify that the speakers you are using with the receiver have the correct impedance (measured in ohms) that matches the receiver's specifications. Using speakers with incompatible impedance can trigger auto mute.
3. Inspect the wiring: Check all audio input and output connections to make sure they are properly connected and not damaged. A faulty or damaged cable can cause the auto mute feature to activate.
4. Unplug and reset: Turn off the receiver and unplug it from the power source for about 10-15 minutes. This will allow the receiver to reset, which might resolve any temporary glitches or errors causing the auto mute.
5. Check for overheating: Overheating can trigger safety features like auto mute. Ensure that the receiver has adequate ventilation and is not placed in a confined space. Clean any dust or debris from the vents to improve airflow.
6. Perform a hard reset: If the factory reset procedure is not working, you can try performing a hard reset. To do this, locate the reset button on the receiver (usually a small pinhole) and use a paperclip or a similar tool to press and hold the button for about 10-15 seconds. This should reset the receiver to its default settings.
7. Update firmware (if applicable): Check the JVC website or contact their support to see if there are any firmware updates available for your receiver. Updating the firmware can sometimes resolve software-related issues.
8. Seek professional assistance: If none of the above steps resolve the auto mute issue, it's best to contact JVC customer support or take the receiver to a qualified audio equipment repair technician. They will have the expertise and diagnostic tools to diagnose and fix the problem accurately.

Always be cautious when attempting to troubleshoot or repair electronic equipment. If you are not confident with electronic repairs, it's best to seek help from a professional to avoid causing further damage to the receiver or risk of injury.
