Yes you have a problem I'm afraid in the pincussion or horizontal width circuit. These circuits usually have alot of high voltage in them and is not a safe place to be experiementing around with. Most of the time, with a problem like this, there are bad capacitors or a correction transistor has failed. If the set is over a few years buy a new one. Good Luck
SOURCE: insufficient vertical height
1 it is due to electrolytic capacitor defective in vrtical output stage. 2 loose contact in vertical. 3 fault due to feedback ckt in v/stage. as per schematic diagram is concern check www.serviceinfo.com

Is the extra width problem something new or has the condition always been there? If it is something new, probably the power supply regulator has failed causing overvoltage to the tv.
