How do i get 1080i, my tv shows im only in 480i. i think i might have it hooked up incorrect. my other tv of another brand is much newer so all i did was connect the hdmi cable from the tv to the cable box...
Hello
Your TV will display all High Definition signals as 1080i True HDTV™ and all standard definition signals will be displayed as 480p.
Component Inputs 1-2
YPbPr(480i/480p/1080i)
These inputs can be used for the connection of A/V equipment with component video outputs, such as a DVD player or external HDTV receiver. Please see Appendix B for signal compatibility.
Input DTV (480i/480p/1080i)
This input is used to connect an external DTV receiver, and can be configured for YPrPb and RGB plus H&V signal types.
As a special feature, you have the ability to adjust the red and blue light beams in reference to the fixed green light beam. This process is called convergence. There are two separate memories for convergence. One, for SD 480i/480p signals; the other for HD 1080i signals. SD convergence should be adjusted while watching an SD source and HD convergence should be adjusted while watching an HD source.
Wide Expand: Enlarges the picture, cropping some of the image on both sides. This Expand format is useful to remove or reduce black side bars on HD broadcasts of 4:3 images with black bars. Available for analog 1080i, digital SD 16:9 and digital HD signals.
InputDTV
This input is compatible with most standard DTV and satellite receivers with component video (YPbPr) outputs. Compatible DTV signals are SDTV 480i/480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Please check the DTV receiver specifications before connecting.
This input is compatible with some DTV receivers using RGB with "separate H and V sync". Compatible DTV signals are SDTV 480i, 480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Industry standards for DTV RGB signals (systems, synchronization, timing, and signal strengths) are not currently established. These inputs will not be compatible with all DTV receivers that offer RGB, HV outputs. RGB, HV signals with less than 5 cables are not compatible.
If your DTV receiver offers both DTV component video signals and DTV RGB, HV signals, we suggest you use the DTV component video signals. Check the DTV receiver specifications before connecting.
Ok.

Yes, the xbox is in HD mode and the TV automaticaly selects the correct operating mode. As I stated, the small printing that is in the upper left corner of the TV screen when the input is changed can be read inspite of the lack of sync. It clearly says that the input is DTV and it is in 1080i mode. So the TV thinks it is running 1080i but something is wrong with either the horizontal or vertical sync frequency. I am not sure which.
I can see on the schematic that there are several lines marked as being 480p/1080i in the sync signal area but I can't find anywhere that there is any signal that selects between 480p and 1080i. I suuspect that the problem in in the horizontal sweep frequency since the vertical sweep frequency for 480p and 1080i is almost the same and the 480p works fine.
