Sir, Pull up the on screen menu and make sure the unit is set to display 1080i or 720p instead of 480i. This may be the issue. Good Luck

I cannot tell the difference between my SD channels and my HD channels. I have samsung DLP tv, HD cable box and bose theater system. I am using an HDMI cable but there is not difference between that and...

In most cases you will not be able to see a great difference between HDMI and Component connections. As far as not seeing a difference between HD and SD signals from your cable box, go into the settings of it and see what resolution it is putting out. If you have a Motorola cable box, with it off and the TV on press the menu button and the setup screen will appear. That will tell you the output resolution as well as what the 4:3 override is set to. Please take a few moments to rate my answer. Thanks....

I don't get HD quality pictures. And it just shuts off for no reason. Am I suppose to get HD channels?

Are you on a actual HD channel? If you do not think you are getting Hd then try this hook up a dvd then select the 480I function and see if that works..

Poor sound cqality on a Samsung DLP TV

If you are receving your HD via a cablebox, check the volume and audio settings in the box's menu. Some boxes have internal volume controls. If the level coming out of the box is below a certain level, you may experience low or poor sound quality. You can also check the audio settings to assure that they are set to the original settings.

5 mostly green verticle lines on all digitle channels. HD ok.

I just called customer support and my issue is now fixed, to my extreme surprise.

It sounds silly (and a tad embarrassing), but here's what I did:

1) Unplug the TV
2) Wait 30s
3) Plug the TV in
4) Test

Apparently even if the TV is "off" for a few days it never fully shuts down unless the power is unplugged. Not sure if this will help anyone else, but I had the exact same problem others are describing. Good luck!

Poor Quality HD Picture

The lamp would make you picture dark.The colorwheel will affect color quality.If brightness is an issue = lamp.If color is the issue = Colorwheel.

No sound on one channel

Just one channel has no sound?

Then you need to change the sound option stereo or mono instead SAP.

Samsung HC-P4752W Blurry ONLY on HD Channels

Similar problem, then about 2 weeks later the SD convergence went out. Changes convergence Amps,,, Now I'm trying to learn what 2 red flashes mean now when I try to power it up,,, it flashes twice then shut down into standby mode,,, I got no picture after installing STK392-040 chips, thinking about trying another set as atleast I had blury picture before. No solder shorts of opens that I can find. TV has always been a pain,,, locking up once in a while such that you can't change modes,,,
