Re: Noise block doring playback of D-VHS tapes
* Do not record program in DVHS mode on an S-VHS cassette. Use of S-VHS cassettes will not allow for maximum performance and may result in head clogging. Use only D-VHS cassettes as recommended in the instruction manual on page 27.
* Make sure that the DIGITAL 3-DNR lamp is ON when playing back a cassette recorded in D-VHS mode. If not press DIGITAL 3-DNR so that the DIGITAL 3-DNR indicator illuminates.
* When block noise appears on the TV screen, clean the video heads with the DFC-2 D-VHS Head Cleaning Cassette (continue up to 3 minutes total). Please refrain from using any other head cleaning cassettes as drum damage may result.

Bad recording VHS or old VHS tapes,will sometimes causes this problems,because of degrading magnatic tapes.Sorry this problems,u did the fixed adjusting manual tracking,that it not fixing the problems,sorry that all u will getting that kind of quality of picture.
The problem is dirt, dust or even mould on the VHS tape. You should look on youtube for video's about cleaning a VHS tape. However if it's really bad there is nothing you can do about it. Commercial VHS were only recorded on SP so the quality of the tape means more signal, so less of a problem keeping the video tracked, even if the tape has patches of mould, likely if kept in a basement!
Guide error or just guide cleaning. You have to get an alignment tape from Panasonic. Then you have study the tape path and know wich guides move and roll and which don't. Then you should demagnatise them all. Then a head cleaning is in order.
then you put the tape in and watch the playback it can be either the main entrance guide or more likely the exit guide these are found right and left sides at the top of the drum threaded up. Sometimes these guides come loose over time this is a job for an experienced tech and if you don't know what you are doing you'll never get the deck in proper alignment.
Because the cable signal is OK, this eliminates the tuner as your
problem and leaves the power supply which is a common problem. It
is a switch mode type which often have trouble maintaining control of
its output voltages and produce trouble downstream in the video
circuitry. Either the power supply is failing which can be
wholesale replaced for about a $150, or something somewhere else is
failing and loading down the supply causing it to overwork.
Usually in this case, you can hear a whine noise if you listen close.
As with all tape related recording equiptment, the path the tape follows in your machine will collect debris which will interfere with the synchronizing playback signals originally recorded on our tape when first recorded. The "ROLLING" is the loss of those synchronizing signals and the "skewing" of the tape where the heads are now reading between the recorded information causing noise at the top or bottom or throughout the entire screen.
SOLUTION for about 85% of machines exhibiting this problem is CLEANING and inspection of tape path alignment best done with a calibrated playback tape for accuracy.
HOPE this helps . . .
Unit might be picking up 60 cycle hum or other electromagnetic field. Is VCR sitting on/under another piece of electronic equipment? If so, it could pick up such from the power supply circuitry of that other device. Try moving the VCR away from other equipment and see if the unwanted sound disappears.
