Question about Televison & Video
Is there a way to adjust the picture size?
You don't give a model number or age of the set so I can't be too specific, but there is an adjustment for picture size (it's actually termed "vertical height") in TV sets. Many newer sets make adjustments through a service menu using the remote control, but many sets have a physical adjustment control inside. I can't tell you how it is in your set, but you can take the back off and look at the circuit board. If you see a small round adjustment control (screwdriver slot for turning) marked "vertical size," "height," "vh" or something similar, that's the one. A little turn one way or the other will do the trick.
Now having said all that, it's also possible there may be bad capacitors in the set's vertical circuit. Is this a problem that just started, or that's gotten worse over time? Do you notice distortion at the top of the picture, like a person's head or other round object looking stretched out if it's at the top of the screen? If so, that's usually a sign of capacitor failure. There are a few in the vertical circuit, usually in the range of 1 to 10 mfd at 50 volts, and they commonly go bad with age. Without knowing what model TV you have I can't suggest specific part numbers.
Hope this helps or gives you a start.
