Re: TV not responding to PC

How are you connecting the TV (composite, component, VGA, HDMI, etc.)? Many displays do not support standard computer resolutions. You might benefit from software such as Power Strip that allows custom resolutions or use advanced settings for your video card.,6241-order,1-page,1-c,alldownloads/description.html

Can't get it out of SAP mode. tried two different remotes. TV doesn't respond.

1. If you're watching TV via a Cable or Satellite box , then the SAP (Secondary Audio Programming) is activated in the box, not the TV. Check with your TV service provider how to activate/deactivate SAP in their box.

2. Only if you're using the TV's own built-in tuner to watch TV (you're changing channels by using the Panasonic remote for CH up/down), then press the SAP button on the Panasonic TV remote to cycle through the SAP options.

Tv monitor went blank when using my pc on it

try adjusting your resolution before you plug the tv into the pc. a 26" shouldn't cause this problem, but it may. Give it a try. If this doesn't work, try finding a driver on the Sanyo website for that pc and download or repair the existing driver. You'll need to use another monitor, of course. I hope you have one.

Shadow on Sharp Aquos LC32GA6E

Unfortunatley, they don't make TV sets as dependable as they used too because they don't want them to last. Your problem with this unit is that your panel is going out. Sharp does not supply panels because they are not cost effective to replace. I hope this helped your cause.

We have a LG42lx6500. when you turn it on after being off for a few hours the picture colour is distorted for a couple of minutes before correcting. At times you can see the individual pixels. Sometimes...


Make sure TV is on the correct channel or input. Check the cables for correct routing from TV to any other devices. Check cables to ensure they are tight and secure.

An analog signal converted to high defintion resolution will cause lines, blurriness or fuzziness in the picture. Change the resolution to a lower or native setting using the media device (cable box, DVD,). This may be an issue that requires a service call to cable provider.

A problem on one channel may just be a error on that channel. If using an antenna, it might need to be adjusted in order to ensure good signal strength. For digtal channels, go into TV Menu. Check the DTV signal. Weak signal can cause picture distortion.

If another device is being used such as a cable box, DVD player or VCR switch between devices and test picture. Check routing of cables that are used to control the image. This should be a series of red, white and yellow cables.

If a VCR with a cable box, make sure the VCR and TV are set to the correct channels for video signal to pass through. If problem is still occuring, try another set of cables. bad cables can cause picture distortion.

Bad cables can cause picture distortion as well. Try another set of cables. If picture is better than when using the cables replaced, this was the issue. If cables are not an issue TV may require service.

What channel do you watch a vcr/dvd on.

It depends on the way you have the combo set up, your instruction manual shows you different ways of doing this, but to answer the question it would be channel 3 or 4 if you are using the RF out ot OUT to TV connector in the back of your combo. You can also view tape and disc playback if you set the TV for VID1 or VID2 if you are using the rca dubbing cables(yellow-red-white).I hope this helps!

Rainbow color effect appears when Samsung LCD plays Wii or DVD

Hello, I have a question which video inputs are you using for your DVD and Wii connections? The reason I ask is because this sounds like video distortion cuased by noise. If possible can you send a picture of the screen when it has this problem and send which video ports are being used? If it is noise in the video you may have a saw filter problem, or a decoupling issue. In any event I'll know more once you send those pictures and which inputs you are using for your DVD and Wii. Thank you, Shuttle83

Remote does not seem to be communicating with TV.

I presume you have replaced the batteries in the remote control and had it checked to confirm it is working if so the most likely cause of faliure to come out of stand by is a currupted eprom (memory chip) within the TV and will require a technician to replace or reprogram
