My son's future father-in-law just gave him a Toshiba CF3266a set that had been replaced. This old TV has been losing vertical amplitude and adjustments were no longer able to restore the size. I have not seen this set yet , but have been invited to try fixing it.
My understanding is that picture shrink had been from both top and bottom. I am betting it is a cap or two that have degraded. This box is a 1991 build. Are there any particular suspects in the vertical amp section.
I am also hoping that the suspects are PTH and not surface mounted. I have no way of checking caps other than a VOM to check for leakage and plain old substitution if I can find suitable replacements.
I am well aware of HV concerns and will keep my fingers away from places that bite.
