How can i plug in my computer on my 1080i - Panasonic PT-47WX49 47" Rear Projection Television

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.

1080i only works with component cables and wont go to 1080p but your hdmi will set it back to 1080i and then switch back to the component cables.

when your using the comp in or hdmi the tv should swithch automaticlly but you must have an HD signal

i would have to know what type of connection you are using. usually in most hd monitors, the vga plug will only show up to 480i/p and some will show 1080i. DVI will only show 480i/720p/1080i and if it has an HDMI you can get 480i/480p/720i/720p/1080i/1080p. you will also have to set you resolution of your video card to match.

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...

Go into DTV setup and switch back to 1080i

I have this same TV and a PS3. You either need to get a HDMI - DVI cable, or plug in some component cables in order to get 1080i from your PS3. Your DVD's will upscale to 1080i and your Blue_Rays will run at 1080i, but be aware, if you play PS3 games that only read 720p on the back of the game box, the PS3 will down convert them to 480p instead of upconverting them to 1080i.

Peace, Bob

the best from what i seen is HDMI, DVI, or comp. in that order.
On my 82" HDTV i use the VGA plug connected to P4 3.5ghz.
everything seems to come to life using a computer and good video card.

The problem is your cabling. Plug the cable from the back of the Comast box directly into the TV. Do NOT plug it into your AMP. See the link below for details. http://www.audioholics.com/education/frequently-asked-questions/why-wont-my-cable-box-video-work-with-my-receiver Good luck.

have you got the slider switch at high definition and not TV at the connecting end at the xbox that leads to the tv input
