Viewsonic N4060w - Sound, No Video

I have a Viewsonic N4060w that has sound and backlight but no video. I have looked through a lot of the forum for similar viewsonic issues. I do have mushroomed caps in the secondary (CS20,CS28,CS8,CS27,CS23). I am going to replace those and I have already replaced CS21, and CS22. My question is I looked over the bottom of the board for other possible issues and it appears that something is missing from C17. Does anyone have any information on what size capacitor that should be or does anyone have a schematic/tech sheet available for FSP276-3F01?

Thanks

Replace ALL the caps with good quality ones. If a spot is blank on the board, there was no cap there. Check the voltages with the set on. If all the voltages are good and there is no picture, then there is another problem.

Is the screen showing a light grey color? Change the T-con board.
