There is no horizontal size adjustment on 99% of all tv sets 25" and
smaller. It is fixed in the scan components used. You adjust the
vertical for correct aspect ratio with the horizontal.

Hi Everyone,

I have a Mitsubishi CS21SX1C TV, chassis no: XL-B-CSX1, built in '93.

The TV seems to be over scanning a bit. How do you adjust the
horizontal
picture size?
I picked up the TV from a dumpster, it had a bad vertical IC. While
debugging, I built the 0.99$ ESR tester, checked all the caps and
replaced a few in the process.
I did find the vertical size pot, but not a horizontal one.

Thanks for any advice, Peter
