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

It sounds to me like you may have a bad volume control switch. Unless you are good at unsoldering and soldering, I would suggest you have it repaired by a professional. Either that or see if you can find a replacement face at a pawnshop or something like that.
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.
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.
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.
