When changing to an HD channel the screen is vertically scrambled. I can hear the audio and can make out some of the picture. Is there a setting I need to change? The TV in general has a yellow haze. I have attempted the contrast, color, tint , etc...

I assume you have cable. The cable HD and digital channels are usually sent in Quadrature Amplitude Modulation (QAM). The cable companies are required to send local channels in the clear but not so for any others. Regular (basic) channels may be clear or scrambled. USA many not be but HBO will be.
So you have 1 of 2 problems: (1) your TV does not do QAM or (2) they have scrambled the channels you want to see. Questions: (1) Have tried direct Over-the-Air (OTA, ATSC) reception for your locals? (2) Can you see the HD local channels on cable? (3) Are you paying for an HD box from the cable company to have the channels decoded? If in doubt contact the cable company.
Current Samsung TVs do do QAM and OTA HD. Alternatives are Dish or Direct to get satellite with an HD receiver using HDMI or 5-cable RCA. Costs are comparable but OTA wins, hands down.
So far as I know the HLN series does not have an ATSC tuner, thus no over the air (OTA) reception. You can probably still get a $40 coupon for an OTA ATSC to NTSC converter. Note that will NOT get you high definition (HD). With Dish you can get HD receivers that do get OTA ATSC both HD and SD. With Direct, no OTA AFAIK. With cable you would need a QAM tuner, not in your TV AFAIK to get clear channels as required for locals. Otherwise cable needs a Set Top Box for digital and scrambled channels although the standard definition (SD) non-scrambled channels work with your NTSC tuner. Too bad there seem to be no ATSC to 5-cable RCA or HDMI HD converters except Dish.
So, You have Five cable leads, The rgb get plugged into there corresponding colors and the other two are your Red and White Audio Input ------Correct? You do not use the in4, that is for a pc with horiz and vert sync. You use input 1 rgb and plug the red and white into the audio input.....your done!
the variation from higher channels from lower channels, few things changes eg frequency, voltage, and current.
take your tv to a w/shop and have the following
tunner voltage pulse variation on a avo meter has you change channels. if the difference of voltage is not unform when you are changing from to channel then you should change the control ic on the rf stage or check the capacitors a round the rf ic for variations in value.
IYou have to have your comcast
box tuned to a channel that is broadcast in HD. On your Comcast remote
hit menu. This will bring up several icons, one is HD. Select that icon
and it will bring up the TV
Guide for just HD channels. Select one and tune to that channel. Once
your on that channel use your original remote and hit menu, then
advance features, then go down to video display and change it from 480
to 980 or 1080. Let me know if this helps.
I had the same problem
you have to set up the componant on DTV.
the signal my be hd 1080i and the only connection with componant that can support this is the DTV port.
the other componant connections only support 480,
i know this problem, happened to me with the comcast Motorola HD receiver box. The key is with the setting in the cable box.
Switch on the TV.
Set the channel to normal tuner channel 3 or HD input.
Turn off the cable HD box.
Press the Menu Button on the Cable box or the remote.
You should see a Menu.
Use the cursor keys to navigate
The default setup is also one of the option, Right click on your cursor keys acts like the computer keyboard enter key and applies the change.
The default setup is 16:9, the shacking would happen if you have set the picture type to "PAN SCAN". change it to either 16:9 or 4:3 Letter Box. The shacking should stop.
Hope it helps.
