my guess is you either have a satellite or cable box try unplugging the system cable or satellite and set for 5 minutes and then plug them back and and restart the unit up and see if it comes back the gemstar module would some times lock up causing this problem . and please let me know if that get's you working or if there is more trouble shooting to be done
Not all DVI inputs are the same. Do you have the manual handy to see if it supports analog DVI?
If it does, you should be able to just use A VGA cable with DVI adapter from your computer to the TV, Select the DVI input on the TV, and make sure your computer display settings are correct (this depends on a few things, so if you need help with that please reply back with more detail about your PC setup)
From looking at the back panel of the TV, the DTV input can be configured as a component video. The M-Link/DVI-HD port is also a DVI with HDCP port and maximum signal handled is 1080i. The M-Link should work with an HDMI to DVI cable or adapter. For this to work, the source must not be a computer or another device using the default computer video output (computers give RGB output). The DTV port would need an HDMI to Component video converter. See this page for some examples: http://www.hdtvsupply.com/hdtocoad.html . The first one in the list (for Netflix and Boxee among others) will give 1080i out if the source is set correctly.
Most DVI-HDMI cables are single link. I've seen some examples where DVI-I (single link) and DVI-D (dual link) cables are not interchangeable. If you have video problems, check your cable. An HDMI to DVI adapters will let you run an HDMI cable up to the TV and then converter at the TV as a separate connection.
Yes this television does support 720p and 1080i. Hear is something that might solve your problem or at least get you going in the right direction.
Problems with DVI-HDTV Connection
• Make sure the DVI device is turned on and the cables are firmly connected. If problems still occur, turn off your device. Re-connect
your device. Reset the power by unplugging the power cord and plugging it back in.
• If you are tuned to the DVI-HDTV input and you’re receiving Unusable Signal message on-screen, contact the manufacturer of the
DVI device for further assistance.
• If you tune to the DVI-HDTV input and you see snow, the video goes in and out, or the video takes a long time to appear, your DVI
device is having trouble sending video information to the TV. Re-connect your device. Reset the power by unplugging the power
cord and plugging it back in. If problems persist, try connecting to the Y Pb Pr jacks instead if they are available or contact the
manufacturer of the DVI device for further assistance.
• If you have bars on each side of your picture, the device you connected might have a switch or a menu option allowing you to
change the picture format output that will fix this. Choose either 720p or 1080i.
Your TV plays High Def material through either Input 4 (uses component cables R,G,B) or through Input 5 (Uses DVI cable).
Today most equipment uses HDMI cable for High Def or it may have a component (RGB) output that you can use. The DVI hookup is best, so you need a HDMI to DVI cable or Component Cables (Red, Green, Blue). You need some source that OUTPUTS High def (ex. 1080i) either through HDMI or component cable. You need to either connect the component cable(R,G,B) from the source to the Input 4 on the TV or connect the HDMI to DVI cable from the source to the Input 5.
You need to set the AV source on the TV to AV5 (if you are using the DVI input) or AV4 (if you are using component cables).
If you want to play Highdef source like Blue Ray then you can just connect the output of the blu ray player to your Tv using either the HDMI to DVI cable or component cable (Red, Green, Blue) and set the TV input to AV5 (for HDMI/DVI) or AV4 (for component).
But if you are trying to get Free High Def from an antenna then you will need to have a component that can OUTPUT high def. The $40 converter boxes don't do this - they simply convert the Digital signal to Analog (non high def). What you need is a High Def TUNER that OUTPUTS High Def. I was looking for one for this same reason and ordered the centronics ZAT 502 HD. But it cost about $80. Then I saw that Tivo had an upgrade deal where I could upgrade my existing Series 2 Tivo to Tivo HD for $99. It has a High Def Tuner in it. So I cancelled my order with Centronics and got the Tivo. In any case if you want Over the air HD you will need a High Def Tuner that will OUTPUT 1080.
A DVI cable does not have an audio connection, along with the DVI you still have to run an audio line from the device (DVD player, cable box, satellite receiver) to the TV. HDMI contains both audio and video.
Initially, pls try lowering the screen resolution of your PC. This can be done at the Display Properties/Settings tab and then move the slider of the Screen resolution towards the left, Apply OK. In some instances, you need to also lower down the Screen refresh rates in the Monitor tab of the Advanced Properties.
If your concern has not been corrected after completion of the above procedures, then other methods can be considered.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
After many hours of research, I was able to fix the missing AV5 channel. I had to access the service menu using code 062596 and the Status/Info button on the Philips remote. There was an error message that had to be cleared and then AV5 needed to be turned on in the options menu. While I was in there, I also turned on the WSCR option, giving me two additional wide screen aspect settings that had also disappeared. I advise you not to go into the service menu unless you do your homework and document each setting before you make changes. Good Luck!
When you are using the DVI connection on this unit it will automatically set the aspect ratio. There is no way to force it into stretching the picture as it will with other input sources. The only way to get to fullscreen would be to go into the setup menu on your cable box and set the "4:3 override" option to one that will meet your satisfaction. I'm having issues with this one skewing the picture to the left on DVI input. I'll crack it open one of these days to see if there are some adjustments that I can mess with on the inside. If there is anything further I figure out, I'll repost.
