1080p ** Longer Available, problems switching to 1080i.
Sorry the story is a bit long. About a year ago I **ticed that my Motorola cable box (1080i) which was plugged into the DVI port on the TV wouldn't work. The TV would show the picture for about 4 seconds and then tell me "** signal detected". I played around with power, input selection, etc and eventually it would work again. Strange thing is that my Xbox 360 was able to output 1080p fine at the time though old style component connectors. Eventually about 4 months ago the DVI completely failed with the cable box - ** way to get it to work. I thought it was the cable box and switched to component for it and everything worked and I forgot about it. About 3 months ago my Xbox failed to work at 1080p and **w only functions at 1080i. At the same time I have problems switching from 720p (or less) up to 1080i using the Motorola cable box (but from 1080i to 720p works without a problem). I have to select a blank input and then back to the Motorola input before it will show the picture properly (otherwise it looks like it's a copy protected signal). I purchased a PS3 a few weeks ago and an expensive HDMI cable. The PS3 doesn't detect a 1080p signal (I've tried all the tricks about settings in the PS3 with ** avail). A guy on a**ther site said the TV needs a firware upgrade. I don't believe this as it used to work fine for over 3 years. I'm capable of replacing the boards myself but need to k**w if there is truely a hardware failure and if so which board is likely the issue. I'm leaning toward the main unit board, KD006, but thinking it might also be the digital board, XD001. Does anyone have any suggestions other than call a repair guy? There is ** Sharp authorized repair in my area and Sharp wants me to ship the set to a center. For the costs of shipping to and from and the parts, I could buy a new tv! Plus I'd be without it for up to 12 weeks. Someone has to have an idea. Thanks in advance.
I'm a sharp servicing technician and since both the component and hdmi have problems, Im leaning towards the Main board also. If it was the digital board, only the hdmi would have a problem.
If you do end up replacing the main board. ONce youve installed it, check to see if it has the latest firmware version. New boards from Sharp are supposed to be preloaded with the latest firmware, but sometimes they are not.
A firmware upgrade is possible because it deals with this sort of DVI/HDMI compatibility issue. It would be the easiest and cheapest
fix. Enter the Service Menu to check what version you have. The
latest is version 1.31

Which cable box do you have? Is it Motorola or Scientific Atlanta?
If it is Motorola then press turn the power off then press the menu button. There should be a setting for ypbr output and use the left and or right arrow button on the remote to change this setting to 1080i
Sounds like the cable box is outputting in 4:3 rather than 16:9, it should also output in either 720p or 1080i/1080p. Check the settings on your cable box and set them to 16:9 and 1080i/180p. If that does not rectify the problem then you need to look at the settings on your Samsung
You have to adjust the settings on whatever is connected to your television. If you have a bluray player connected to your television with an hdmi cable you should be able to receive 1080p but you have to set the bluray player to 1080i. The tv picks up the signal automatically. From your cable box or satellite tv box you cannot get any more than 1080i from television programs at this time. You can get 1080p from bluray on demand. In certain circumstances you can get 1080p over component cables as well as an hdmi cable but in most cases you will only get 1080i. Once again you have to set your connected device to 1080 to get it on your tv
Resolution such as 1080p,1080i etc. set by your source of the signal, for example, if your cable box set to 720p that is what you going to get from the TV. Cable box is ont capable of resolution more then 1080i because there is nobody broadcast in 1080p yet. Only way you can get 1080p is BD player, upconverting dvd player or media player. 120 Hz is just a frame rate convertor - takes stendard 60Hz and doubles number of frames to 120. So, you will see 120 frames per second instead of 60.
1080P is a quality you'll only get with a blue ray quality video. Therefore, you won't get 1080P on cable tv. If your cable provider has HD channels available, you'll be able to get 720 or 1080i quality video (on those channels only). For the best quality, make sure you are using an HDMI cable. Just be sure your cable box supports an HDMI output. Your Vizio definately supports that type of input. If you have a PS3 or alternative blue ray player, you'll be able to watch 1080P.
