Every time I use my component video, the screen is cut on both sides. I wonder if it can go full scene or wide screen. Need Help.......

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

The program you are watching is not formatted for wide screen viewing.

There should be a screen mode button on your remote. Full, Wide, Zoom, and Etc. Sounds like your putting a 4:3 video into your 16:9 screen. Which causes the normal "box" video to be stretched to the wide "rectangle" video. Just keep the screen mode on Full or Normal. You should have empty spaces on the sides of the video and when a HD program comes on, the sides should fill in automatically.

Replace Vertical IC.

Hey!

The full screen shots are the actions scenes that were filmed in IMAX... there's nothing wrong with your player or disc!

I think your video drum needs replacement. You can get replacements for your brand of Combo on the Internet.
