Samsung CW-29Z308T problems, fuzzy screen

Screen has very good focus, but for example when face is making slowly move then it loose focus and make ghost effect. It looks like picture is digitally processed, has little squares, something like Divx. I tried to turn off any digital effects but no changes. Only when i truning on DNR (Digital Noise Reduction) ghost effect seems to intensificate. Maybe changing some values in service menu can fix this problem, but dont know what mostly means. Thanks for respond.

By the way, signal has very good condition, i`m using AV device. When using air antenna ghost effect is not so visible. It could be caused by noises.

Can someone tell me what means options in service menu ?? f.e. ABL MODE, TNR Enable etc.

Ok, i had all this options write down, np to back to default values. You see, service maunal i have nothing tell about meaning options (or maybe i need other service manual). So i think its better to do something than sitting and waiting for samsung company, which propably will not fix this problem. I dont know how with Samsung in other countries. What do i need is to know what this shortcuts in service menu means. Have you got any service manual for this model ?? I have only manual with service menu, no any explaination about meaning. The most wanted meaning are: ABL Mode, ABL TH, AKB Time, S - ABL, P - ABL, VSU, H_EHT comp, V_EHT comp, PIN EHT comp, AFC EHT comp, TNR Enable, LTI Enale, CTI BW, CTI LP, CTI Gain, CTI Coring, IF Comp Filter, DHYAPRESC, DHCAPRESC, Neg peaking, DCE Gain, CORBP, SVM RW, SVM Delay, SVM Coring, SVM Gain, SVM C_Gain, VCR Mode Cnt, SLLTHD, SLLTHDV, THRSEL, LPCDEL, AM_Prescale. There is much more, but mostly i know what they mean.

Regards

P.S. I plug PC using S-Video or Composite video and there was no ghost effect (speccialy when .using S-Video, composite had a very very little ghost effect).

You may find these terms used and explained in other service manuals.

Can you give me some urls ?? I tried to find some others manuals but didnt find any special.

Found some clues
