Mitsubishi WT-46809 Problem getting HD from DirecTV

I bought this model about 4 years ago thinking it was only a few years till I would upgrade and actually use the full capabilities of this set. Yesterday, the DirecTV installer hooked up a Model H20, DirecTV HD Receiver. After much long anticipation I was agast to discover that the set would only work on the 480i and 480p resolution settings. The 720p and 1080i settings only show what resembles a scrabbled screen. I checked the monitors advance video settings and the only options listed are 480p and 960i, even the though the label on front of the set seems to indicate it can operate at 1080 ("HD1080 Series"). Has anyone else been confronted with this dilema and is there away to upgrade the set or am I just out of luck on this?

I have found some info on this, please read: "For standard (480i) connections, there are three S-Video/ composite-video/ R/L audio sets. You would use these for any of your standard video connections such as a VHS VCR. There are two component-video (Y-Pb-Pr) connections, each with three RCA jacks, which will accept input at 480i and 480p (such as the output from a progressive-scan DVD player, for example). Each of these two component-input sets has a corresponding R/L audio connection. Finally, there's a single component-video connection with five RCA jacks, handling Y, Pb, Pr, H, and V (the last two are for horizontal and vertical sync signals). This last component-video connection will take input at 480i, 480p, and 1080i. You do not have to use all five connections. If you have a 1080i-output device, such as the analog output from an STB digital high-def broadcast tuner, with only Y-Pb-Pr output, you can connect to just the three Y-Pb-Pr connections on this five-jack component-video connection. As with the other component-video inputs, the Y-Pb-Pr-H-V set has a corresponding R/L audio input jack pair. The Y-Pb-Pr-H-V component-video connection will also accept an analog VGA-connector output. To make such a connection, you will need one of the adapters with a VGA jack on one end, connected to a cable whichs splits into five separate cables, each terminating in the appropriate type of RCA plug (Y-Pb-Pr-H-V)." This might be your solution. It worked on my Mitsubishi WT 46809. I have moved the component cables installed by the Direct TV installer to the second row of component-video connection (labeled 1080i) and finaly my DirectTV HD receiver is recognizing the 1080 signal.

    DirecTV installed a new 5 LNB satellite dish as a free upgrade. The tech had a test set & tested the cable where it connects to the reciever. Good signal there. He wants me to upgrade to the HR20 reciever, but I am under the impression that that will only give me the local channels in HD. I still see no difference in quality when comparing TNT & TNTHD.

    I'm starting to believe that the TV is not HD compatible, although Mitsubishi markets it as such.

    Try the following:

    You do need to activate the HD input on the TV.

    Send the TV into HD mode by pressing menu 1-3-7-0 and cycling with the input button to get the HD mode.

Wharfedale dv832b software upgrade? I bought this a ouple of years ago and sinc then it has never updated itself eve though it is enabled. I have waited and nothing haseer happened. A couple of weeks ago I...

Just get into the Wharfedale site and upgrade it with latest software available, that suit to your DVD-M3. It will take some time, say about an Hour to complete the donload and installation. Don't stop as download stops, the softwre must be installed, and it will happen only after the full download. After sucessfull download, the set will propt you that has done sucessfully. Till then, never switch off the net connection, or do nothing at set end. If installation is not successful, the fault you describe here will occur. OK.

I am recently upgrade win7 hp nx9110 audio output device not installed msg getting how to resolve

Ok this is kind of common with Windows 7. Although everyone thinks its new its really not just a fairly bug free OS. The HP models running Win7 actually are using the Vista or XP driver for audio. I just ran into that issue a few months ago when upgrading a Pavillian model.

Replacing the Convergence IC's should do the trick. But it is not a easy repair do to the disassembly requierments. I would recommend calling Mitsubishi at 18003322119 to get a local service facility to come out and give you a estimate to repair.
