Hi there Q: Did you push the CD Door by force? If yes ... 1: you have misplaced the mechanical wheels .. or broke some thing. 2: Or the second possibility is that the Driving motor rubber is broken the answer is to service it. Good Luck Hope this helps

My best advice is to do a factory reset on the system and then set it up again like you did when you first installed it. Unless your daughter physically damaged cables, the system should work OK. It's no use trying to work out what she disconnected as that will take even longer than a factory reset.

OK I fixed it. One of the CD's had gotten stuck between trays in the loader. I pulled out a few CD's by forcing open the trays gently. However even after removing as many cd's as possible one was still stuck. 1. Remove screws holding cover plate on in back and sides. 2. Remove cover. 3. Lift face plate latches and lift over top of unit. Remove serial cables from face plate and place aside. Remove screws from back of CD tray unit and bend back metal tab with flathead screwdriver. Lift CD unit up on one side so you can get your fingers up inside underneath and push stuck cd towards tray openings. You can gently force top few trays out. You may need to shake unit so that stuck cd reaches open end. Pull out CD. 4. Replace faceplate and connect serial cables. Plug in power cord, power on unit and make sure trays will eject normally. 5. Put it all back together!

The dvd's lens has probably been damaged due to electrostatic discharge or even a shortcut.
You'll have to replace the optical pickup to fix it.
It's better to have it done by a panasonic/technics technician. Go to your local official service.

You haven't put it back together correctly and one or more of the mechanism gears is slipping.

You'll need to take it apart again and make sure everything is engaged as it should be.

Hi

Sounds like the timing for the drawer has been knocked out of alignment.You can take top off to remove the discs...the timing can be realigned( assuming there are no broken parts). The trays can skip gears and sometimes be returned to their alignment but usually the plastic breaks easily and some important tab gets broken off unplug the unit for a minute, that is a "reset" or sometimes there is a tiny hold with a button inside, but its usually got "reset" written somewhere next to it If all else fails, look for the SAMS photofacts or the service manual, one of the authorized service centers will have one. Panasonic makes excellent equipment usually made to be fixed .The best way to re-align the timing is top obtain the service manual. Here, it will give you detailed instructions on what marks to line up....you may be able to get a service manual from UED.net...They are a Panasonic parts dist.

Please get back to us if you have further query else please accept the suggestion.

Generally speaking, an amp protects 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. Eure 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.

F61 usually means the amp has detected a short.

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