Question about Samsung LN32A550 32 in. LCD TV

Open Question

I have a 32 inch, Samsung HDTV, model number LN32A550P3F. I have HD Cable and have it connected to the TV via the HDMI port. Whenever I turn on the TV, the picture is streaky white and green lines, and the sound is a very load white noise sound. After 10 seconds the tv turns off and turns on again. I've tried all three HDMI ports and have the same problem. I now have the cable box hooked to the TV via the S video connections.

SOURCE: ilo 27 inch hdmi/dvi hd tv monitor

Hi, I'm afraid that not only a cable is needed but an analog (vga) to digital (dvi) converter/scaler as well. The iLo LCD Display V27DMBX-U12 can hook up to a PC using the DVI-I connection only. As you said, your computer has the standard 1D15 pin VGA connector. Another possibility is if your video card has a composite video output (normally a color yellow RCA female) or an S-Video output which will both connect direct to your iLo LCD Display V27DMBX-U12. For the RCA connection all you need is an ordinary RCA to RCA shielded wire cable and for the S-Video, an S to S Video cable will work. There is of course the question about the quality or the resolution. Good luck and hope that this be of some help to you. Pls post again how things turn up. Kind regards.

ok your tv does not come with the very best sound, you have to get a receiver 7.1 or you can use the optical wire , that's if the system you are using has that option.

SOURCE: PS3 (Pal) won't connect to Sylvania HD TV

I just figured it out last night - if you have used your playstation on an hd tv previously, it is set at the highest resolution possible - 1080p. You need to take it back to that tv, and go to display settings on your tv. If you select HDMI as they type of connection you'd like to make, it asks you what resolution your tv supports. In your tv instruction guide, it should give you this information. Check mark all of the resolutions your tv supports, making sure not to confuse 1080i and 1080p. After doing this you can take it back to your other television and it should work.

SOURCE: Low volume on LG HDTV

I encountered the same thing using the HDMI interface on my new TWC cable box (Motorola DCX-3200). After a little bit of research, I finally fixed it by changing the digital audio mode in the cable box using this procedure:

1. Be sure the TV is on and connected to the cable box.
2. Using the cable box remote turn power OFF.
3. Immediately press the MENU key on the remote. The USER SETTINGS menu should appear on the TV screen.
4. Select the ADDITIONAL HDMI SETTINGS >>> menu item.
5. The ADDITIONAL HDMI SETTINGS menu will appear.
6. Scroll to the AUDIO OUTPUT item and select this.
7. Change the setting from AUTO to L-PCM.
8. Return to the main page
9. Using the remote, cycle power OFF.
10. When the cable box is turned on again, you should be good to go.

I realize these instructions are specific to the DCX-3200, but there may be a similar setup option available in your cable box as well.

The problem here is that the cable box is by default configured to use Dolby Digital audio, which requires an additional 10dB of headroom to deal with the boosted LFE channel. If the cable operator hasn't taken pains to set the system up correctly (and most haven't, apparently), the digital audio level sent on the HDMI interface will be approximately 11dB down from normal analog line levels on the HDTV channels. Changing to straight linear PCM sets the TV receiver audio level on the HDTV channels to match the levels on the non-HD channels.

The only problem with this fix is that if you intend to feed a Home Theater receiver that uses Dolby Digital processing with the cable box output you will lose the Dolby encoding feature and be forced into straight 2-channel stereo. For a simple installation like mine where I'm just feeding the TV, this fix works fine. If you have a more complex setup that takes advantage of Dolby Digital features (when it's available in program material), you may have to live with the problem.

For a technical reference on why this happens, see http://www.megahz.com/specimages/Dolby/LM100%20Cable%20App%20Note%2011-05.pdf

Hope this is useful.

How do I get my PS3 to work over hdmi?


Try swapping out HDMI cable. The version of cable. (1.2, 1.4 etc ) might be too old/faulty for PS3.

If your Tv is HD ready and not Full HD lower the video quality in the PS3 settings

Can record Sky programmes but not view live.


You must connect up the TV to the SKY box, via Audio Visual cables too, in order to watch, recorded programs. You need to hook, up, Component, HDMI, or Composite, You select it by an EXTERNAL channel.
Connect the cable running from the wall into the "In" port on the Sky Box HD receiver. This cable brings in the signal to your receiver. Make sure the cable is securely fastened to the receiver, otherwise you might experience image and audio issues.
Attach an HDMI cable into the HDMI port on the Sky Box HDTV receiver. The HDMI is a single cable that provides both HD audio and video signals.
Plug the other end of the HDMI cable into an available HDMI port on the HDTV.
Power on the HDTV and the Sky Box HDTV receiver. Press the "HDMI" button on the TV's remote control. This will display the cable contents of the HD receiver onto the television.

Just connected our directv hd receiver to the tv via component cables, because we just bought a blue ray player and the only output for that is HDMI and since there is only 1 DVI input we had to change the...


You may be able the settings of your directTV box to stop frustrating you. If you help me identify the model you are using, I can research the proper menu choices you will need to choose to select the correct features. There are many different directTV set-top boxes available.

My own home theater setup did the same thing, and my solution was to use component cables from the PVR instead of HDMI cables. It is too bad your blu-ray doesn't allow for this configuration.

My work-around until I realized that using different interconnects fixed the problem, was to turn the TV off and then on again whenever switching from HD to non-HD sources. This fixed my problem, maybe it will fix yours.

I hope that helps.

HDTV goes blank when connected to Fios HD-DVR or Fios DTV recvr.


If you can first connect the Fios box via component and that will rectify the issue and still allow HD. HDMI is funny, if there is anykind of communication issues between the TV or the Fios box you see what happens. You might also call Samsung to see if there is ANY firmware/software updated for your TV specifically to fix such an issue with the Fios/Mortorola connection. If there isn't then the issue is the cable box since the TV works ok on HDMI with other devices.
