Question about Proscan PS56700 56" Rear Projection Television

1 Answer

No Picture I have the PS56700 and it no longer has a picture. Playing a DVD works but the cable box does not have a picture the screen reads "Unusable Signal". I changed the digital box, checked the box on another TV and put another TV in the Pro Scans spot to eliminate all outside issues. Any ideas why no picture?

    Yes, I did all that and changed cables. I even brought another TV in the room and hooked it up to the same setup and it worked. I switched it back to the Pro Scan and still no picture just says "unusable signal". If I play the dvd that has a picture on the set.

    I unpluged the TV and pluged it back in to let it reboot and that worked. Thanks

Fix tv picture


If the TV is receiving its signal from a cable TV box or DVR then you need to find out if the problem is in the TV or the cable box/DVR. Connect a different source to your TV such as a DVD or Blu-ray player and play a DVD movie. If the problem occurs again it suggests the TV needs repair. If the TV works OK when playing a DVD movie then that suggests that your cable box/DVR needs repair or replacement.
If your TV is receiving its signal directly from an antenna or cable outlet on the wall then you should try replacing the cable wire from the wall to the TV with a new wire. If that doesn't help then your TV probably needs repair or replacement.

I have a 46" DLP TV, I have sound but no picture. But I can play a DVD, and it works fine.


Does the dvd have picture when playing or no picture no matter what?

You can try switching cables.

Do you know if the screen is on?

OK, just kidding. If your TV or its remote control has a Reset button you can press it twice to reset the TV to original factory conditions (but you lose all customised picture and sound settings). If the TV receives its signal from a cable box or DVR, try connecting a different device such as a DVD or Blu-ray player and play a movie disc. If the problem on your TV screen still exists that suggests the TV needs repair or replacement. If the picture is OK when playing a DVD movie that suggests that your cable box or DVR is faulty and needs replacing (usually free from the cable TV company).

My DVD is playing my videos in black and white .. It's a Panasonic tv model is tc-L32c5


follow the steps. God bless you
Insert a DVD lens-cleaning disc into your player and press "Play" to clean the DVD laser, eliminating picture problems due to read errors. Do not use a CD cleaning disc as the brushes on these discs can damage your laser.

  • 2 Wipe your DVDs clean of all visible marks and dirt using a lint-free cleaning cloth moistened with rubbing alcohol or glass cleaner. This further fixes read errors which can damage the quality of picture and sound.


  • 3 Disconnect your DVD player from the TV or receiver you have it connected to. Reconnect the DVD player directly to the "AV" or "Video In" port of your television, firmly pushing the plug into place, to eliminate possible noise from the receiver and ensure a clean connection.
  • 4 Connect your DVD player using an S-Video, component video or HDMI cable. Standard yellow/red/white RCA connectors cannot carry the high-quality signal that DVD discs are capable of transmitting, and will display a particularly poor picture on flat-screen high definition televisions. Use an HDMI cable, if your television and player support it, or a red/blue/green component video cable.
  • 5 Press "Setup" on your DVD remote and enter "Picture Settings." Make sure your DVD player is set to display images in the correct screen format ("Widescreen" or "16 x 9" for HDTV sets, "Standard" or "4 x 3" for older square sets) and scan mode. If you are using a DVD player that supports "Progressive Scan" on an HDTV or flat-screen set, activate this setting; for older sets, choose "Interlace" if given a choice.

    Issue with our Toshiba 50H82 - overnight it has stopped playing DVD's properly - a solid black rectangle obliterates 75% of the screen. Any idea?


    Hi,
    Do you see same solid black box in all inputs or just in dvd picture?
    If solid box appears only with dvd picture then its generated by dvd player, check dvd player Menu and turn off any subtitle settings.
    And if solid black rectangular appears in all inputs of TV like cable etc then check Close Caption feature in TV and turn off CC function.
    Hope this will solve your TV problem.
    Thanks.

    HDMI ports 5 and 6 on the back of tv no longer are working. (We had a series of thunder storms so don't know if that is how they got damaged or if it was something else) but moved HDMI input cable to HDMI port 4 on tv and everything is working again. Service call placed for warranty service on tv to repair bad ports.

    TV & DVD HookUp (No Box) Can't get picture


    As far as I know, my Go Video machine when there was no box involved...

    The cable came from the wall to the IN of the Go Video box. Then another cable coming from the OUT of the video box and to the IN to the TV. TV should be on channel 3. As far as I can remember, I don't need to push the TV/VCR button, but instead, have to channel down to below channel 2 on the TV to the LINE/INPUT selection. Once you go there, and the Go-Video machine is on, you should be able to see a clear picture.

    You'll push the TV/VCR button if you want to toggle back and forth from the VCR picture to the TV picture (which will be technically blank since it's on the 'line input selection.)

    Hope that helps.
