Question about Philips Magnavox 20MT133S 20" TV
The top ~1¼" of the picture appears to be overscanned into top ~½" leaving the top 1¼" of the screen empty (black). In effect, it appears that what is supposed to appear in the top 1¼" of the screen is being jammed into the top ½" of the picture.
That makes it really tough when watching an NFL game on Fox with the game details posted in a bar along the top. :-)
There is only one unmarked adjustment port on the reay of this set.
Thank in advance for any help in correcting this issue.
First, my apologoes for the delay. I was called out on site for a major production and my access here has been limited. I do have the service manual for this set and intend to look up the pffending circuit tonight. I have listed the items you provided as target components for checking and will post the relevant parts of the vertical circuit.

Try to reset first if nothing happens we proceed another solution;
Resetting the TV
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can saved time.
1. Unplug the TV power cord from the power outlet for 3 - 4 hours.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.
hope this may help;

A missing power supply voltage, defective vertical output IC, or a component associated with it is likely bad. A bad connection or blown fusable resistor may be the cause of a missing power supply voltage
Thanks for using Fixya!
