Question about Apex Digital AT2702 27" TV
I believe my APEX TV is beginining to "bloom" and I am missing some of the picture on the sides and the bottom. I would like to simply adjust the horizontal and vertical sizes but there are no external adjustments. (It used to be these controls stuck out the back of the TV, but no more.) I opened up the chassis (CH-10C) but could not see any pots to adjust, except for two on the YOKE. Can anyone offer me some ideas as to how to adjust or correct the horizontal and vertical deflection? thanks Basil
OK...I paid a whole $50 for an Apex AT2702 that had [undisclosed] vertical zoom, horizontal shift, vertical shift and width issues. Before I raised hell for the person who sold it to me, I decided to first exhaust all alternative solutions.
I found that in order to tweak these settings, you have to be in service mode and must have a service manual which I can email upon request.
BE SURE TO DOCUMENT YOUR CURRENT SETTINGS SINCE ANYTHING YOU CHANGE WILL AFFECT YOUR SET'S PERFORMANCE !!!
1-Reduce your tv volume to 0
2-press the MUTE button on your original tv remote [you'll see "Mute" in red on the screen]
3-AT THE SAME TIME, press MUTE on the same remote and MENU on the tv controls.
This set your tv into service mode [there will be a red "S" at the top-center of your screen.
You'll need the table in the service manual page 47 where there are V-SHIFT, H-SHIFT, V-ZOOM, E/W WIDE default values that will need to be changed. WATCH YOUR SCREEN as you change the values to ensure you don't over do it.
If you have news ticker and sports scores issues, you'll want to be tuned to CNN, FOX, ESPN or whatever to see how your changes are applied.
If you have tv guide problems then tune to that channel or press info and see what happens when you make the changes.
BE SURE TO DOCUMENT YOUR CURRENT SETTINGS SINCE ANYTHING YOU CHANGE WILL AFFECT YOUR SET'S PERFORMANCE.
This has worked for my set and you may attempt this solution on yours at your own risk.
I'm no longer pissed off that I got a bogus tv because it now works just fine and I can see everything!

I took the advice of Deafbyipod and ran with it. It is true, you have to make sure your tv volume is all the way down (to 00), then hit the mute button (and see MUTE at the bottom of your screen), then simultaneously hold the mute button on your remote and the menu button on your tv to access the service menu. Then while the Menu 00 button is highlighted, hit the right arrow on your remote, this will take you through different options. Keep arrowing over until you find the V options. Arrow down to the V Shift. hit the enter button and use your remotes' up and down arrows to adjust the picture. The V correct option moves the screen also, we changed several of these options to make it look right. As Deadbyipod suggested, you need to have something at the bottom of the page to see where you're at. I also found it helpful to pull up the Guide to adjust it too (since by adjusting the vertical it cut off the top of the guide). And finally, I couldn't figure out how to get back to the tv, I simply shut the tv off and back on.

After much frustration and tinkering i found the solution in my case..
My APEX AT2702s was cutting off the screen about 2 inches on all sides.. I read much documentation and was having trouble getting my TV into service mode. The way I did it was,
reduce volume to 0
press mute on tv
then press mute again on remote, while at same time pressing menu on the tv, not the remote.
the tv will flash the normal menu for about 1/2 a sec then will go into service mode. I thought I was to press mute and menu on the remote, which did nothing. Hope this helps too and good luck

There are no adjustments that you can adjust to make the size and width larger. Your need to the power supply fixed as the B+ is lower then it should be. These adjustments your asking about are tweaking adjustments and if they are not on the board then they are preset or in a service menu. They do not make any major changes in the picture. If all of a sudden theres a change in the height or width, its not an adjustment. Good Luck

To whomever it may concern,
I have an Apex PF2720 with the same problem. The TV quit, so I checked out the fuse and found it to be blown. I also found one of the rectifier diodes to be shorted. After replacing all the rectifiers an the fuse, the TV now works, but the verticle size is reduced by 2 inches on both the top and the bottom. My son-in-law bought an identical TV and has had the same problem. I need some answers.
