I have an elderly Panasonic TC-29V26A, Chassis M16M which has served me well for many years. This model was called "The One Up" I believe. I wish to make a small adjustment to reduce the vertical overscan. Can someone please tell me if there is a service menu I could access, and how to get to it if it exists.
Thanks in anticipation,
Bill.

My TV doesn't have many of the control buttons in the access codes you listed. It is really getting to be an old clunker now.
Thank for your kind effort to help.

Oh silly me, I am sure the M16 does not have a service menu come to think of it,
Just a Vertical pot somewhere on the chassis, but it sounds like a Electrolytic in the frame stage is getting a high ESR, and that is maybe affecting the linearity and reducing the height.

Yer blood is worth bottlin!
I had a sneaking feeling that this chassis was just on the cusp when service menu's were being talked about but yet to be implemented. I don't mind getting in the back there but I would have kicked myself if I had found no vertical size adjustment. The set has always overscanned and I thought it was about time to make those circles round instead of slightly oval. ( I remember the old hot chassis drill, so I will be reasonably safe)
Many thanks for the info.

There was a Vertical Centre and a Vertical Amplitude easily adjusted on the rear centre of the chassis. The old BBC testcard "F" showed me the way things needed to go, and then a final tweak to round using a conveniently sized breakfast plate as a guide. Easy as - - - -.
Nostalgia running out of my ears!
Thanks.
Bill.
P.S. A couple of tiny holes in exactly the right place on the rear cabinet means that if it ever needs adjustment in the future, a suitably filed knitting needle will do the job nicely.
