I have a 10 year old Sony Handycam Video 8mm - Model #CCD-TR91 that has served us well. The unit is on it's 4th battery, but still works, kind of... I suspect the trouble is with tape alignment/tracking since some previously recorded events and sometimes new events as well do not display properly. Usually I lose half the picture with tracking lines and at times it also is in Black and White only.
I do not see any electronic tracking adjustments similar to similar vintage VHS VCRs. Can anyone provide a reference to a service manual or a tracking adjustment procedure? At this point I am inclined to replace the unit with another since price has come down so much over the years, but before I did, I wanted to take a shot at aligning it myself.
Thanks in advance for your help.
Bob
