Question about Insignia Televison & Video
About half an inch to an inch vertical overscan. All I need to know is how to access the vertical lin and height controls.
After I get the vertical solved, I'll go and try to find if there is horizontal overscan as well. If you happen to know where the horizontal size control is (if it even has one) that would be appreciated also.
Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

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!

if you have already tried "code search" then you may have to return that remote and get a different name brand of universal remote.
