Hello, My Samsung VP-D80 has a problem : In cam position, picture in LCD screen or eyescreen is bad at some moments : I think there is a contact or connexion problem, but not permanent. I' looking for tips to open the front part (containing lens and sensor) of this camcorder, so I will verify connexions. Where can I get datasheet or service manual in download? Or if someone knows how to do... Thank you in advance!
