Sony CDX-M850MP Remote wont work when front panel closed.
The front panel on my player was not working properly although I could open and close it with the remote and adjust volume etc. The display itself was the only thing that would not work. I purchased another set which was faulty (no audio on 3 speakers) this unit had had the ribbon replaced on it by the previous owner. I set about changing the complete front, a very easy job, and everything went well. When I powered it up all the lights worked and the display worked well. The only problem I have is the remote control will not work with the front panel closed but works perfectly with it open. Would be good to get it working right again, any help would be appreciated. Thanks Bill.

The problem is the flexible wire strip that cracked. I just had the same problem. A guy has them on auction on e bay. Type in model number and flexible replacment for search.
1. Unscrewing 2 the two screws that connect faceplate to motorized flip bracked. One on each side.
2. Unscrew the screws that are connected to the back plate. Plate directly behind faceplate with Blue LED.
3.Unclip backplate by sliding Deck out 1 inch. Two clips on each side.
4.Unclip the waferboard/circuit board from the back plate.
5.Remove Flexible wire band that connects the faceplate to backplate.
6.Attach new flexible wire band to deck then to face.
7. Reclip everything, Rescrew everything.

The gears have probably come out of sync, meaning the tray is riding on the limit switch. You need to remove the deck, dismantle and re-sync the drawer mech. Check the limit switch isnt bent, it's quite flimsy
if yes then look under ballance and check theat rear and front ballance is in the middle if it is then for temporarily replace the front speaker with any old speaker if that works then you need new front speakers if no then the radio is broken
but what you could do is rewire the back speakers so they also play though the front ones too this can be done from behind the radio
find the rear right positive and negative wires strip the insulation but dont cut the copper wire cut the front right speaker and attach that to the rear speaker wire do this for both positive and negative
rear right positive ..v ..v I...I I...I I...I .I.I..........< strip cable but do not cut metal .I.I..______________ .I.I=_______________ <<<front right positive .I.I I...I I...I I...I I...I
There are 6 or 7 phillips head screws that keep the top on; remove them and pop the top. This will give you access to all CD's. Remove them all, then plug the unit back in and press the open close button and check for normal operation. If it still wont open, it's broken a gear and needs to be serviced. You may consider replacement of the unit if inoperative, the replacement model is priced at $129.00 and a repair would probably cost the same if not more. If you need further help, post a comment and I can help you further.
I had the same problem with our 5-CD Sony carousel player CDP-C535
(manufactured Nov 1993). I removed the top metal cover, and loaded five
audio CDs into the carousel. After I closed the table, I pressed the
carousel tight so that it stayed close, and hit the play button. The CD
player tried to push the carousel out with quite a force. I needed to
warp me fingers around the front panel to keep the carousel closed.
After a few cycles of forcing the carousel to remain close, and caused
two separate strong "clucks" from the gear area, the CD carousel became
operational again. The diagnosis of gear problem seems right.
Broken gears. The current replacement 5 disc is a CD/DVD player and sells for $129.00 at Sony or any other Sony retailer. The cost to have a service center even estimate the repair would be more than 50% of the replacement cost. Hope this helps
Dear friend, my sony dvd drive tray opens and closes itself, it is mostly a problem related to hardware. in my case I removed the IDE Data cable connected to the dvd drive and reconnected it again. now my dvd drive works well, I think the problem was the IDE data cable, may be a loose contact.due to this loose cantact,a jung signal goes to the dvd drive, which opens and closes the tray frequently without our knowledge.
