My Panasonic S-VHS VCR (model NV-sv121EB) has now been exchanged 3 times and even this one is playing up. My current hardware is all Panasonic and consists of TV + DVD player + SAT box + VCR. The menu graphics jump/flicker at all times other than in AV2S mode when the screen goes black & white and the menu graphic stabilise. However, when disconnecting this and rigging up either a BUSH or HITACHI VCR (both of which are not S-VHS) the menu graphics are always fine surprisingly no incompatibility problems etc. As an experiment I simplified the scenario by simply connecting the problematic Panasonic to a portable TV and NO problem was experienced the menu graphic were fine! It seems that some sort of interference is occurring with this particular VCR. The budget Bush + Hitachi VCRs coped with the full set up perfectly amazingly with no problems! The following points came to mind/done; 1. Played around with the tracking problem persisted. 2. Used quality THOR brand scart leads- problem persisted. 3. Phone Panasonic who do not know why this is occurring ! 4. Set VCR to shipping condition & re-tuned it to no avail ! Any ideas out there ??? if so, you should be working for Panasonic !! Many Thanks ..
