To do this adjustment, you should enter the service mode option. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. http://electronicshelponline.blogspot.com/ Service mode entry, adjust and exit procedure to many popular brand TVs are given.
There are Horizontal and Vertical size controls behind the back cover that need to be adjusted using a hand held tool. This adjustment requires a trained tech. High Voltage from the set is dangerous.
However, there maybe some limited controls that may help through the on screen menu.
To get into the setup menu, you need the original Remote that came with the TV.
Hold the Menu Key down until a box appears in the corner of the screen, then press 9,8,7,6 Enter. this takes you to the service menu. Just scroll through the items to find Horiz Size and Vert Size.
You need to adjust "vertical height" in the service program. You need to put the set in "service mode" to do this adjustment. If you google "enter service mode RCA F32665" you should find the procedure. It will be listed in abbreviated letters such as VERT SIZE or VERT HT. Follow the instructions for entering service mode and saving the data closely!! The data you change will be listed as a number between 1 and 63. The number will only need to reduced by a small amount and you can still see the picture behind the data and watch it shrink as you adjust the number down.Always burn the new number to memory (if required) before exiting service mode. Good luck

this set is known for cold solder connections on the vert output as well as the b+ supply line comming from the flyback xformer that supplys the voltage to the drivers. It could also be the vert output capacitor, The two waveshaper caps in the predriver stage of the vert, the filter cap off the flyback or the vert drive b+. Without going in and getting a schematic it will be hard to say. sets like that unfortantly these days are throwaways. NO NO NO dont throw the set at me I did mean that way!!! Its the cost factor of repairing getting the parts as well the the service diagram. it all adds up.
