Question about Sanyo DP19648 19 in. LCD TV

5 Answers

HD Problems When I am on the HD channels, sometimes after awhile I will get snow, or a green screen, or just colored lines across the screen. Sometimes its after 5 minutes, 10 minutes, 2 hours, and sometimes it might work just fine.  And sometimes the audio works, and sometimes it doesnt.  Usually, I have to go behind the TV, unplug it and the HDMI cable, and then it will work OK again... but then who knows? It happens again in 5, 10, 100 minutes.  Ive already got a new HDMI cable, so I know its not that.  Its either the TV or the cable service.  Any suggestions???? have an antenna only. The audio and video went out at the same time, but the power remained constant. About 2 hours later the video came back on, but no audio. That was 3 days ago (2/25). I've tried everything in the manual up to and including hitting the reset button twice to reset tv to factory specs. Anyone have any suggestions?

    It's hard to believe that after all this time out of the blue something just came loose without any help from a fall or push etc.

Well, I would suggest new cables, but sounds like you got them. You might have a static build-up that is interupting the signal. Try unplugging your television for at least 4 hours. Better yet overnight. This is what is called a "hard reset".  Computer routers are extremely known for this but it also does happen to tv's and stereos. Usually you just unplug the cable for at least 10 seconds and re-plug it back in and everything is fine. 
I would suggest removing the back of the tv and looking for any loose or broken ground (black, brown, or green) wires or solder pieces.

    tv main menu, find a "input signal" setting. (such as antenna or CATV) make sure the antenna option is highlighted or selected. 


    Also on main menu, you should be able to go to the "sounds" setting and make sure speaker "ON " selected. 


    It may be the antenna itself or the antenna input. Try resolving with any tv settings first. You may also want to try hooking antenna up to vcr, and vcr to tv and seeing if that makes a difference.

    Oh yea, just so you know, with all the television stations just recently transfering to digital, they may have not worked out all the kinks yet, because others have been having similiar problem. If all this is recent and yet to be determined permanent, then just wait it out and make sure everything is Kosher on your end with all right settings and connections. I don't believe it would be a problem with the television if it doesn't happen 24/7

Hi!

Are you using a grounded supply(Three wire connector to a 3 pin socket grounded supply).

If tv is not grounded then it can result in failure of components aswell. Please use a grounded supply to resolve your issue.

Please ask for further clarifications.

Thanks

    Try using external speakers to see fi they work.



    If you have lost the audio internally it will need servicing. BUT: first check your settings. Make sure the SAP is OFF and the audio is set for stereo and for internal use (or external if you have external audio going).

    Or try audio from either the headphone outs or phono audio outs. If you have audio there is will be cheaper to add a PC type speaker system externally than to have it fixed as the repair charges will be at least $150 or more.

    And, a good set of pc speakers with subwoofer, etc. will be much less.



    Please ask for further clarifications.



    Thanks

I would have the cable service come out and check your lines in to the TV. You may be losing signal strength.

I have a multi colored line running across my screen and I can't get my digital antenna channels? Any ideas? Tv is only about a year old and I have unplugged it for an hour to reset it but it didn't w


Hi it sounds like you have multiple problems with your tv. First you said that there were no digital channels. The tv has a bad signal board. The second problem is the colored line running across the screen. That could be two things either the screen itself is bad or your t-con board is bad. The t-con board would be the cheapest of the two to try. You can get parts from www.interliquidparts.com

Green line down left side and geen snow


Horizontal or vertical bars on the screen could be from an ac line interference, adjacent magnetic field, bad input wire connections.....especially HDMI connector cables. A bad HDMI cable causes all kinds of unwanted picture interference. Check the conditon of all connection wires for proper fit and function. Keep in mind the method in which you connect your tv will result how the tv performs. As well this line problem could be a circuit issue too, requiring a technician to look at it.

26PFL5520D/50 DVT PROBLEM


If the lines across the screen are made up of coloured blocks, then the problem is likely to be a weak signal.

Digital channels are broadcast in groups called multiplexes. Sometimes one multiplex may have a weaker signal than others, and so you experience problems with up to 6 channels when all others are ok.

If it is only one or a few channels then just wait and see what happens, because it may be transmitter works.

If you have problems with all channels it could be a connection or antenna problem.



If the lines are just straight lines, then try resetting the TV as follows:

Switch on the TV

Press and hold the menu button on the side of the set. The settings menu will appear. Hold until the menu disappears again.

When you release the button, the TV will take up to about 90 seconds and then reset.

The TV will then show the original screen when the TV was new.

Press ok when shown.

Set language and country settings.

Move down the list and press ok to re-install all channels.
