What is the best IC replacement for original IC part# STK393-110?

Yo don't. The TV's resolution can't be changed. Only the signal resolution from the source can be altered.

The TV is a fixed pixel device. The panel has a resolution of 1920x1080 pixels. The incoming video signal is scaled to fit that display. If the signal is 480i then it is deinterlaced to make it 480p, and then scaled up to make it 1080p. The amount of detail in the picture doesn't change. It's still a 480i image. It's just blown up to fill a 1080 panel.

The TV reports the resolution of the incoming signal before it is scaled. If you have a BD player you can see the effect of changing the resolution setting from 480p, to 720p, to 1080i, to 1080p 60, to 1080p 24. The last three (the 1080 resolutions) shouldn't look too different with a Blu-ray apart from movement because the native picture is 1080p 24 and the TV is simply converting it back to 1080p 24 for display.

960i is a funny resolution. That would be achieved by line doubling a 480i signal. But it's not one of the VESA HDTV timings. TTBOMK there's no Blu-ray or HD source that generates a 960i image. So even if you could generate it then the TV wouldn't understand what to do with it.

Have you tried a different input like a DVD to ensure the issue is with the TV? If the issue is indeed the TV then replacement of the video card (Or digital board) is warranted. If there is a separate board with all of the video inputs on it that would be the video board. If the main board in the unit has the video connectors on it, that is the digital board.

480i is the highest resolution of your tv. The tv has composite, s-video and component inputs in the back. The manual states that with component connections are dvd compatible allowing you to enjoy the highest quality image playback than using s-video. Dvd's resolution are 480i or 480p. I'm guessing it's more 480i than 480p since the tv is a crt tube tv and does not have any of the digital inputs for higher resolutions.
