I power up my head unit and no music comes forth, it has power, no error coded, cd player reads, and the system still beeps when changing source, menus ect. Opened it up, nothing looks burnt, or unhooked.
What happened... was working well, hit a bump, got static then nothing, so i figure something maybe toasted will keep digging deeper, any advice on where to start?, what to look for?
would love to get back up and running.

Hi Wendy CD-Rs and CD-RWs have a component that ordinary music CDs do not have -- an ...This additional track space includes the power memory area (PMA) and the ... which tells the CD player what part of the disc it is reading at any particular time. ...uncorrected error on a music CD only means a bit of fuzz or a skipping noise. GOOD LUCK !

This can often be solved by opening the cover and blowing on the optical head to displace dust and any debris that is fouling between the optics and the actuator that controls the head position. It isn't fool proof but will fix perhaps 40% of units. Take a can of air duster (aerosol blower) and blow the little pick-up form the distance of about 1 inch. It will bounce around in the wind but don't blow to hard. Give it a gentle blast and then try the player. If it doesn't work then try again this time but blow harder.
My first guess would be that the loading belt is slipping. This will prevent the cd from loading completely and thus won't read. The belt costs around $2-$3. Care must be taken when opening up this unit.
It happened to me today and it passed after a while when i was arriving home. Try to reset it by taking the power source off for a couple of minutes then try again.
Don't forget about your system definitions, it will be restored to default.
If you want to know whether the region coding can be hacked on your unit then you need to state both the make AND model. If it's reading DVD's but not CD's then the reading head is faulty and must be replaced, but it's rarely an economically viable repair.
Pull the top off the unit and use a can of Dust Off (compressed air) and clean out the inside. Then use a Laser lens cleaner and run it thru the unit once or twice. This is considered normal maintenance on a 300 or 400 disc changer that should be done annually. If it still won't play a disc, replace the unit, the replacement model is around $ 199.00. A repair would easily cost that much. Hope this helps.
