Question about Samsung HC-P4752W 47" Rear Projection HDTV-Ready Television
My tv is around 2 years old and it will not work in 480i or 1080i mode on HD. However, it works perfect in 480p mode with native off. Let me explain the symptons a little better. When I set it on 480i I get a "no signal" message. When I set it on 1080i mode the picture looks like a 3D movie without the glasses and the picture is skewed a little. The problem seems to have started when the power went off one day. I have Directv with the HD100 converter. I use and HDMI cable but get the same results using composite, etc. I have a newer LCD HDTV which works perfect in all modes with this same Directv HD receiver.
I think Bluenadas is right that it's the digital board. To be sure, I would suggest opening it up and looking for any bad capacitors. Those are small round things sticking out of the board. If they are bulging or leaking anywhere, that's your culprit. Replace the board they are on and you should be fine. You can purchase boards for this here: http://tigerdirect.partsearch.com/GetModel.aspx?MfgName=Samsung&BrandName=Samsung&ModelNumber=HCP4752W&page=3 However, unless there is something visually obvious, like the bad capacitors, it's going to be difficult to be 100% certain that the digital board is to blame without replacing 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.
