Question about Samsung Televison & Video

1 Answer

We have a Samsun LN-T4071F LCD TV. The screen is all white and colored vertical lines. We disconnect the HDMI cable from the Dish box and the screen stays that way. We turn the TV off for a couple hours then when we turn it back on the picture is normal for some random amount of time when the problem will manifest itself again. fosterfamily1@verizon.net

Vertical lines on tv


Possibly a bad HDMI cable connection. Remove cable,
then reconnect, with the plugs firmly in the jacks. If that doesn't
work, then borrow an HDMI cable from a friend and see if that
fixes the problem.

AOC PD4264 Screen fault


Extremely blue color temperature that cannot be adjusted; some false-contouring artifacts in dark scenes; no picture-in-picture; limited connectivity with just one DVI and no HDMI inputs.
If use as a TV monitor:
The number of colors you can display is controlled by the video card installed in your computer. In order to display more than 16 colors, the proper video card driver must be installed. Contact your computer or video card manufacturer to obtain the latest driver from them.
If you are watching standard-definition or Cable/RF signal on an HDTV, the picture may appear to be of poor quality. This is because the TV is designed for viewing HD or at least digital content. Your best bet would be to upgrade to a Dish Network HD receiver and connect it to the TV with an HDMI cable. Similarly inputting analog signal to TV from your DVD player will not appear to be of great quality. A newer DVD player would most likely have component video output which would look much better. To get even greater quality, an upconverting DVD player connected with an HDMI cable would look the best. You could also upgrade to a Blu-ray disc player, which is capable of playing HD Blu-ray discs as well as DVD's at higher resolution. A less expensive choice could also be a streaming media box. Hierarchy of inputs for good picture quality:

I definitely hope that you have gotten this resolved, but if not, here are some reasons this could be happening. If you have tried the same HDMI cable on other devices, such as the PS3, then it sounds like the problem is in the HDMI output on the receiver. Have you tried another HDMI cable in a different input on your tv? It could also be the input on the tv. But so far, it does sound as though this is a receiver issue, and the receiver would possible need to be replaced. You can e-mail me if you have any additional questions. My e-mail is becki.barned@dishnetwork.com.

Picture issues


Greetings caesar975,

Unfortunately if you chose to view the non HD channels in wide screen format, you are going to have the top and bottom of the screen cut off. Eventually this will not be a problem when everything goes to digital. However presently non HD channels are presented in 3:2 ratio where as HD is 16:9, So your choice really is to view them with the lines on either side for now.

I do not have an answer for the white flickering lines.

To get the BEST picture out of your 1080p unit I highly recommend using HDMI cables to hook it up.

I hope some of this helps.

Sincerely,

Dorothy
Go Ahead. Use Us.
