This lense is used by LG also in their several models, The lense which we get in local market are recycled (as ststed by few LG  friends). If you get it from any LG service centre ,it works very well  without any adjustment  but if it is from market, you need to adjust RF level for CD to 1.3v PP  on test disc instead of 1v PP (original adj). If you measure RF  level in those lense it is always less than 1v pp  which makes its strange behaviour.
Thanks and regards

Recently I had same experience with new lens PVR502.It is used in Philips DVD. When you hold upside down the lens, with sliding holes to top, adjust left side preset & VCD,MP3 lens starts working!
