Well, first the 100Hz issue. Your TV will display a descriptor or the signal it is receiving, not a descriptor of the picture you are watching. Your TV panel has a native resolution and frequency. In your case, that frequency is 100Hz. Everything, like it or not, must be converted to 100Hz for the TV to work. In your manual, you are simply adjusting setting which smooth the picture and make it flow better than it would at 50Hz. This feature is slight of hand and is probably working just fine. As for the picture fitting the screen; HD programs fill the screen of HD channels.... SD (Standard Definition) programs use black bars on each side when on HD channels. You can use any available wide or picture size feature your TV may have to stretch the picture. You may be unable to stretch the picture, due to restrictions (some TVs will not resize HD formats).
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
That is an ITC008 chassis and the problem you're referring to is called a breathing picture. One fault I am aware of in this chassis/model is the connector Bl103. I have seen a couple where the connector failed and had to be replaced. Could open it up and locate the conntector and see if it's vibration sensitive.
Before you fool around with this, it may be under warranty. Check that first. Second, does the picture stretch in both directions or just vertically? If just vertically is it more pronounced at the top?
Sounds like you may have caps going bad . Adjusting may tend to only stretch the the picture too much . Also when you say horizontal are you saying the top and bottom are closing in ? If yes then your problem is in the vertical section . If side to side then check the horizontal section . Good luck
