There is only one possibility of noise [high-frequency] to LCD TVs. It should be coming from its back-light inverter board. The ferrite cores of the inverter transformers at the back-light inverter board can make this noise; if there is any loose fittings. Check it.

WD 73835 has ghosting images during dark or red scenes


Make sure your contrast isn't set too high. Most ghosting is caused by either contrast, brightness or tint issues. Try adjusting these settings. Also check if there is a Dynamic contrast setting for your TV as well as this can cause ghosting also.

Take it back-before the warranty runs out. Once in a great while you get a lemon. Stand firm. Don't let them 'fix' it.. You want a new one. The warranty time clock is still running while they are trying to fix it. You want another one-with a new warranty.

Sounds like you have a faulty DVD drive. If you are still in warranty Microsoft should either repair/replace the console, call them and explain the situation. Otherwise, if your warranty is out, you could replace the DVD yourself, there are many places to pick up the drives, ebay is a good place to start also xbox-scene.com would be able to help.

Please rate if at all useful, thanks!
