Okay I have a problem with my cd drive/player. It keeps jumping and lagging when playing cd.
Also it wont read my nav dvd at all..
I've already tried cleaner dvd, no results. I did remove the cd drive and friend of mine who's
somekind of expert of electronics did a check out for it and also cleaner the pickup eye or what ever it's called.
But the problem still remain.. I've heard if you adjust the bias of the eye it could work but my friend did not find
that adjustment. Is there anything I could do or so, I would not want to buy new one because it costs 600euros = 840dollars..

Anyone can do check out how much it costs in US. My other friend is at florida right now and he could deliver new one for me if
it's cheaper there..

Here's a video what it do..


I would apreciate all the suggestions
Thanks
