JVC KW-NT30HD Screen not working

Unit is working just fine, other than the screen not displaying anything. The screen is backlit, if I touch anywhere on the screen I'm still changing stations, skipping tracks and changing navigation. I just can't see what I'm doing. I've reset the unit (both by popping off the faceplate and disconnecting the car battery), and I've pressed and held AV/MAP for a few seconds (JVC's tech explained that this should turn the screen on/off).

    Also, the unit was professionally installed 2 years ago, and has worked without a problem for the past 2 years. This just started 2 weeks ago, all connections to the unit are intact and all the wiring is still insulated.

It sounds like the screen back light is burned out, on a lot od LCD screens they use a very tiny fluorescent tube to light up the screen and it sounds like this backlight had burned out.

SOURCE: I have just fitted a

Hi

If you connect the red and yellow together then attach them it should work, use an inline fuse if it has not already got one, the yellow should be ignition live and the red constant live although on JVC I have seen them the other way around also.

Hope this helps
Regards

Dan

SOURCE: Remote unit is draining my car battery. Unit

Hi Rog,

I would first ask you, 'What has changed'?

Then, 'Why do you think this unit is the cause'?

Have you had the battery load tested? Not just voltage but it's ability to hold a charge, to provide the necessary power under load conditions.

Try disconnecting the negative terminal overnight. If when you reconnect in the morning, it's dead, the cause is not a drain.

Get back with me

it sounds like you don't have the yellow wire going to a constant power source. the ;yellow wire provides the power for retaining memory.

SOURCE: 95 xj battery died replaced battery radio comes on

The Radio unit may need a 4-6 digit security code. Locate the owners man and other paperwork, (usually in the leather binder for jags) the radio code is in there along with it. No owners man? Call your local Jag dealer and give the parts dept your V.I.N. # . the parts guys will assist you better and wont pressure you to make an appt for service....
Once you get the the code, turn the ignition to the on position-without the engine running, simply enter the digits using the radio station preset #'s..... as soon as the last digit is entered, you'll hear a "beep" sound, indicating the security is deactivated and ready to go... good luck!

I can't see anything on my jvc kw-avx820 indash. Everything on the screen works fine. The USB stopped working the same day the screen went out, idk if that has anything to do with it. Noticed that you

standard solution if it does not work is to check for power and ground.
replace unit if both are present. Going further find out if there is a place that has a checker for your model and maybe save some money. The USB is probably the input for display so you might take apart to see if anything is out of place.

KW-AVX710 Screen stays black (off) untill I hit the open button

So I decided to verify all the connections after I got frustrated with it. Everything was correct except one wire that was on the new harness I got that for my car that was labeled "12V fused" (supposedly the key on power source). I tested it with my volt meter and it did not have power at any time, even with the key on. The constant power source wire was hooked up so that's why I was able to open the face and eject CD's and DVD's but not do anything else (like when your ignition is off). So I ran a new wire from my fuse panel and everything works now. Just like my Thermodynamcis professor says "nullius in verba" (take no one's word for it), just because the wire was labeled doesn't mean it's right! Hope this helps.....
