Screen overscan too great

The image on this TV/VCR is too large, resulting in perhaps 20% of the image being lost off-screen. I don't see any obvious CRT gun adjustment trim pots, other than brightness and focus. I'm afraid I will have to give up fixing this issue without any schematics or further information. Everything else is normal on this Sansui TV/VCR, so I hesitate tossing it for a new one. Thanks for any advice...

I would check to see the power supply ic and make sure its not putting out more then its supose to as I remeber those are between 125 and 130 volt dc output. as maybe the High Voltage shutdowns not working.oh is is too long and too wide??? if its only like too tall there is a small opot on the pcb thats for the verticle height buit its so small and easy to break off and if you do that the set will lose the verticle sweep totally. good Luck

This should be a Dish Network setting, not a television setting.

How do I adjust tv screen size to fit laptop? lap top projection is to large for operating properly. to big.

Assuming you have a flat screen 16x9 TV, make sure it is set to screen fit so that there is minimal overscan. The button should be called pic size or aspect ratio. Also set your laptop to the same resolution as your TV or as close as possible to a supported resolution.

How do I enter the service menu on an Emerson EWF2004 CRT Television? (Pictures of the OVERSCAN ISSUE will be provided if needed.)

Older sets had vertical and horizontal size controls. If you have the horizontal size control, turning it counterclockwise will reduce the size of the picture horizontally and reduce the overscan.

Magnavox 37MF337B/37 overscan only sometimes problem

This TV has a pixel resolution of 1366x768p

It will accept a 1920x1080i input from a high def source , but running a PC at 1920x1080i/p will cause the problems you describe, depending on what the PC is sending to the TV, because PC signals are not the same as high def.

Your PC should be set to a resolution as near to 1366x768 as possible. My PC allows 1280x768 and 1360x768. Try one of these for best results.

There are no settings on the TV to solve this problem.

Has VCR to TV hookup been changed? Cabling errors will result in no display from the VCR (no tape video/audio, no menu display). If you are using the TV aux/VCR input connections, you must select this input before anything from the VCR will be displayed. If you've verified hookup is correct, then perhaps something is afoul with the VCR. Try hooking it up to another TV.
