My ws-65611 always stay in 480i even with HD signal.

It sounds that a software update is necessary. Contact the service centre for Panasonic, to get the latest software to this model Plasma tv.

Its main digital board has to be replaced. It is a skilled work. If you wish to get more details about this work, check the site linked below and pull up older posts there.

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.

Tries CBS or NBC channels have HD if displayed 1080i than ur box is working.The shows must say HD or Display 1080i to work HD programming.

Connect your component cables to the DTV connections.

Sounds like you may be trying to use a resolution or scan rate the TV does not support. Many of these televisions do not support 720p, but DO support 1080i.

Good luck.

Greetings,

In the input assignment menu make sure that the DTV (the only 1080 input on this tv) is set to Y/Pb/Pr and see if that fixes your issue with at least the HD-DVR.

BTW- the HDMI information "1080i HD can only be selected if TV has HDMI inputs". is not correct.

You Can Not Change. The TV Recognize the signal on the INPUT.
If the signal is 480i than the tv shows 480i
If the signal is 1080p than the tv shows 1080p (if supported)
If you try with your areal antenna (for now digital broadcast is maximum 1080i (in USA) The TV itself doesnt "upconvert" lower resolution signals.

grab your TV remote and go to setup. check your input settigs and change them from RBG.

Problem more than likely with the xbox, as the output stream of data from the game platform is not always consistent...accordianman
