My Apex AT2702 has under scan. Both vertial and horiz. sweeps are pulled in about 1/2 inch. Any componet change experienced in order to fix?
Try to reset first;
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;
Regards,
VOTIT

You can get into the service mode by entering the special code from the remote control. But, you must have the service manual in order to get that information.
Go to this web site:
http://www.worldwideelec.com/apex_asc_site/apex.html
Then download the service manual for the model marked APEX AT2702 & AT2702S. It is not exactly the same model, but the service mode will be the same as far as I know.
Then, go to page 48 of the manual and follow the instructions on entering. There is a table given for all the adjustments that can be made for the set.
Menu 04 will give you control of the vertical size and position, etc.
Hope this will guide you sufficiently to get it adjusted properly.
click also below for the manual:

Being that it is an apex tv those are basically "throw away tv's".They are made quite cheaply and offer no support/parts. Are you planning on repairing this yourself?
Thanks,

Well most of the modern tv today doesnt have vertical hold anymore.
this
symptom is caused by a trouble in the IC integrated circuit or the
vertical oscillator circuit. let the service guy do the job if u dont
know anything about this. good luck!

No! Under scan has nothing to do with vertical hold.
