No red on mitsubishi ws-65908

Set the unit to DTV input (this uses YG,PyR,PbB) . then in customer menu go to advance features, SD video format & change from 480i to 1080i. There is no 1080p

you have to use a good HDMI cable

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.

No input on a WS-55511 is capable of 720p . Inputs COMP1 and COMP2 ONLY accept 480i/480p . Input DTV accepts 480i/p and 1080i . When using Input DTV with a component connection(YPbPr) and you get a green or no picture then you will need to navigate the menus and setup input DTV for YPbPr instead of RGB.

Using the DTV input on the back via component cables to an HD source you then need to make sure the input assignment menu is adjusted to Y/Pb/Pr

is your RGB cables are the same output from your tv...are you connecting from where dvd cable box sattelite box, if you are connecting from a box exs output of cable box is what colour are you using? for your your output to your tv and what input are you using of your tv set.[input 1is it video input 1,] or comp? let me know...

Component inputs 1 and 2 will only pass up to 480p. to get 1080i you must use the DTV component input.

that tv set is only good enough to receive a 1080i signal at the DTV INPUT. unless you can change the output of the blue ray it will be outputting 1080p

there is a setting in the menu under setup i believe it is called
"LABEL VIDEO INPUTS". check you owners manual. you need to make sure that
the DTV input is set to YPbPr NOT RGB.

Looks like you are going to be working with the following:

 

1080i (HDTV) • 480p (EDTV) • 480i (SDTV)

 

Hook up depends on what else you have connected to the TV.  If you have nothing connected to the DTV component inputs, I suggest using those, as it will allow up to 1080i.  Otherwise, use the 2 other component connections directly to the left of the DTV connections.
