Help with Geometry on Toshiba 57HDX82

[EVT]

Hi guys,

After owning by Tosh 57 HDX82 for almost 6 years i decided to try and address overscan through the service menu. I read an online tutorial where the individual noted it was easy to fix the geometry by eye once you had set your overscan; unfortunately I found this was not the case and I'm unable to get it back to a state that I'm happy with. I have tried the string method but I kept having the horizontal strings drop.

I can't seem to locate a geometry grid for this TV; if any knows of where I can get a grid or has another practical suggestion to fix this it would be greatly appreciated.

Thanks.
