www.eserviceinfo.com have one for the dcm 280....

There is special disk for sale for cleaning lenses. Otherwise you will have to take apart your changer to clean lenses. If you have some experience and tools - you'll be fine.

not if its a toll call. try 2 clean the eye with a q tip

5V standby OK? Bad capacitors with bulging tops.

If you don't wanna send it for service, open the chassis of the player and free the CDs from the tray. Its highly likely that the CDs came off the trays and got stuck inside.

Hi there, this lens may be dirty or it may have a thin layer of heat film that is causing it to not read in a consistent manner. i would try to clean the lens with a good CD lens cleaner. if the cleansing doesn't restore the lens to its original reading state, this will confirm lens assembly failure and you will need to replace this assembly.

hello you mean buzzing,humming cause is a high missing broken ground and it needs service by electronic shop............make shure is not missing any wire that must be connected or undervlotage working............saludos

Probably drive belt that rotates the carosel inside is not lining up properly,or the belt that moves the laser mech into position,sounds like its just not lining up properly

i had err 2 screen. removed case (about 10 screws, took just a few minutes) and found 1 disc was had been knocked out of the tray. removed all discs. replaced case. works fine again
