20 Most Recent JVC DX-T9 System Questions & Answers

When one says he replaced a fuse or a fan it is always helpful for the Technician to know - was it necessary or just a shot in the dark?

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

If you know how to measure, then check Transformer output (Low voltage). If not good, replace the transformer

If you check at the back of your hi-fi, you'll see a projection at the top where the cooler fan is located. The most likely reason is that your fan is not working (as required). In this system, the fan is turned on automatically at high volumes >=10, because then, the amplifier starts to get a temperature rise and without proper cooling the system might fault.
Try check and see if at these high volumes the fan is running, if not, then that's what needs to be fixed. Alternatively you can try running an external fan to see if it will produce the desired cooling effect.

That means your trays are on Child Lock (this is a safety feature to prevent any accidental opening or closing of disc trays by small children when listening to your favorite tracks.)
To solve this, simply switch off your radio to Standby and hold the power button...whilst holding the power button, press open on the tray that is locked....the system will display UNLOCKED on the display of your hi-fi.

That should be it. To lock the tray....repeat the same process on the particular tray u want locked.

It does have an aux input with two levels but this isn't suitable for a turntable. A suitable input should have RIAA correction with a sensitivity of just a few millivolts for a magnetic cartridge.

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 a lot more clarity and toss in a load of CAPS. Can you hear the CD Motor spinning? If so, probably this https://www.fixya.com/support/r29927004-dvd_player_or_cd_player_not_reading If not, the CD Unit has failed, or the power supply to it. A JVC Service Centre should be able to fix it. ..
