Hi and welcome to FixYa,

Offhand your described problem could be:

  • top and/or bottom - vertical deflection, most likely a failing capacitor or the Vertical IC. In some instances, it could just be a cold solder on any of the IC's pins;
  • all 4 sides - likely to be a main B+ issue. Often, this would be the main filter capacitor. In some instances, this could be a failing component in the horizontal section.
This would require opening the unit. This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

How do i get the closed caption off of my magnavox smart series tv?


There is a little button to the right of the "0" that says "CC" for closed caption. Just keep pressing it till the option "closed caption off" appears on the screen. Then, hit STATUS EXIT, and you're done.

Horiz adjustment on magnavox 20ms233s


I can tell you genericaly what the fault is. I have not worked on your particular model, or have the service manual for it.

It is not an adjustment. There are some electrolytic capacitors that typicaly go off value with age. These would be located in the horizontal scan amplifier area.

The set will have to be properly serviced in order to bring it back to normal operation. This is not something you can fix yourself.
