Question about Wanlida Group Malata 500 DVD Player
Hi all, CD's play okay, but DVD's (commercial, not burned) spin without being recognized. Opened it up and laser lens is clean. Any ideas? Laser starting to die? Thanks, GENE
Could be But most of the time when a tech says a laser assy is bad Its not. It could be a simple grating adj on the pickup assy that alot of techs dont have a clue what it is. This alighnment requires speacial tools and is not advised if you dont know how to do it. What it does is adj. the laser postion onto the prism inside the pickup assy. Or youer problem could be a tracking/focus Gain or offsetr alighnment. This has to be dont looking at the rf waveform from the pickup assy drive circuit via an oscilliscope. These are not unfortantly a consumer adjustment as well. If its an inexpensive player, such as more then a year or so old or under 75 bucks , it probably wont pay to have someone look at it. My friend , this is the times of the throwaway world!! Good Luck
