Our RCA D52W19 TV is playing in standard 480dpi (Satellite, DVD, and Wii). How can we get it to play at 1080dpi, like it used to?

Well that settles the problem then.

The Wii is not a HD output source. It only displays 480p. If you wish to connect an HD source, you must connect through an HDMI cable or a component Cable. HDMI is better.

Hi
U can connect the wii on ur tv . connect the component video output of ur wii to the component video input of ur tv. normally component video connections need three RCA chord for video and one two RCA chord for audio input. component video will marked as Y,Pb, Pr.
ok

What to do if you have an all snowy picture (blue screen or the TV displays unusable signal-no signal or no sync)
1 – If you are using a digital cable box or satellite receiver (make sure it’s on) and be sure your TV is set for either CH3 or CH4 (which ever you usually view it on). If you usually view it through video inputs (video1 or 2 etc.) make sure the appropriate input is selected.
If you still don’t get a signal see if you get picture using the DVD or VCR (if available) if you do than plug the satellite or Dig. Box temporarily into the place of the DVD (unplug DVD) you may have to use some A/V cables (RCA yel./red/wht like the ones on the DVD) to hook to the tv from the sat./dig. box. If you get a signal then the sat./dig box is ok. If not the Sat./dig box is not sending a signal and is either defective or needs to be rebooted (unplug wait 5 min try again).
2 – If you are using standard cable or antenna (source) if possible check that the source is good by connecting to another TV. Otherwise try running the source into a VCR and then out to the TV using video inputs (RCA yel./red/wht like the ones on the DVD) and then selecting the appropriate input. Try seeing if the VCR plays using standard CH3 (or CH4)
If the VCR plays on video input but not when connected to CH3 (CH4) then the tuner of the TV may be defective – see if you can use the VCR to change channel using the VCR remote.

Check the rca guide too see supported formats and check to make sure the disney dvd matches that format.

Hook up a dvd player to the rca jack inputs, select "video" on tv.
Press "play" on DVD...

it might work like older tvs where u use a menu button to go through settings then u change settings i have an older tv and it is frustrating

Do you have HD cable or satellite? You need to make sure that they are connected to either a DVI, HDMI or Component (Y,Pr,Pb) connection. Depends on the age of the set you made need to get the Mitsubishi adaptor for HD. And to be correct the resolutions are listed as 48i,480p,720p or 1080i. DPI is used for printing or scanning as it refers to Dots Per Inch. In television we refer to lines.

Try the old RCA/GE channels of 90/91 or 92 to get to the inputs. Or try entering channel 00. Let me know if that works.
