Panasonic C9700U Turns On, Works but NO BACKLIGHT

Hi, this morning i putted my Panasonic CQ-C9700U faceplate on the player, and everything worked well beside the backlight! i can see the graphics and text that it use to show but it veryy hard without backlight and impossible at nightime. first i thinked that maybe there was a bad contact on the faceplate plug but i checked and every contact were okay! its really annoying to have a dark screen, especially since i use MP3 cds so i cant read the song titles. is there anyway to get a technician service manual or something for this model so i can follow the dimmer/backlight contact?
oh yeah i also disconnected my radio 12V just to "reset" it and it didnt fixed my problem

    actually i dont think the bulbs burnt because there ONE bulb that still lights up (the SOURCE button, the only button that is always on, even if the radio is turned off) i mean it would be very strange if all the bulbs burnt at the same time excepted this one, i think theres a bad contact somewhere

    I dropped mine and think a bulb or all of them may have broke. I can still see the display very dimmly when I odly enough shine a light at just the right angle on it. Everything else works fine on it. Any idea where I could have this kind of thing fixed?

It sounds like the mini-bulbs burnt out. Any good repair shop will have them in stock and it shouldn't cost too much. We charge around $35-$55 to do it.

    Sorry, you're wrong. It is VERY common for the bulbs to all go out at once. If they are in series, one goes = all go. And if they are in parallel, when one goes it increases the current through the remaining bulbs and they blow. Trust me. I repair that type of display problem on a weekly basis and know from experience.

I bought a car with a panasonic deck in it, I think, because i found a remote in it, so i am hoping ot purchase a deck faceplate for it, but i cannot tell which model the remote in the glovebox matches....

a faceplate will cost you quite a bit, you're better off buying a new radio. The last time I priced a faceplate for a $99 Sony CD player, the faceplate was $119 !

Sorry, there's no way to repair the CD, if faulty. Try looking for a "reset" a VERY tiny hole somewhere behind the "door", on the face of the radio chassis...Using a paper clip end push into the tiny hole for a few seconds, ignition/radio on...If you can't find a reset...take it to a friendly local car stereo shop and ask them to diagnose the problem ($40).
Good Luck

It is possible for those bulbs to break from severe impact (the filaments will break before the glass).
What i would do is look in your yellow pages to see who SELLS car audio in your area (There's a million in Phoenix). Find one that's close and preferably one you are familiar with. Call them and ask if they do repairs, and if not if they know who does locally. Most shops usually know these kinds of things, because they get asked all the time.
Also, shops prices vary, so if you get multiple names, call around to see who has the lowest rates, but keep in mind you sometimes get what you pay for!

My shop would usually charge around$45 for that type of repair.

Panasonic CQ-C7103U having faceplate attachment issues.

You can order a new faceplate from Panasonic, if that is the problem. (You may find one on ebay, too?) Carefully check the connection before spending anything, as I wouldn't want to suggest spending on something that isn't broken. If you have electronic skills, check the internal connections from the jack to the internal board and every other connection. Also look for cracks in the board. If found, a light coat of solder can fix that up fairly well, and not cost anything.

Of course, this is all a guess, and I would verify everything yourself before doing anything. Good Luck.

MY panasonic CQ-C9700u starts to skip sound threw the speakers when i put it over 25 on the volume but the bass box still goes until 40?

Hi Lando,

Your Sub box gets its signal from the PReamp output. This means your problem stems from the CQ-C9700U amplifier section. You may need service from Panasonic on this one, or a new Head unit. I cannot think of any adjustment that you can do to eliminate a skip sound.
