Default Old Panasonic CRT TV, Adjusting Picture Geometry


"AR"

Hi, I want to adjust the picture geometry on my 1993 Panasonic TC26-L1R
(chassis M16M) crt tv. The picture is zoomed in and there are parts in
sides and upper border which are not visible.



** The usual cause of an oversize pic is because the EHT voltage is low.

If the pic size also changes with brightness, that indicates poor regulation
of the EHT.

EHT setting is normally via a trim pot on the main PCB.
