HDMI blank picture

Using the HDMI cable, I have a picture for a few moments when my mac mini boots up, but then the TV (Video 7 output) goes black. I know the mac mini is working because when I plug it into a monitor, the picture is fine on a monitor.

Re: HDMI blank picture

Check to see if the TV can support the resolution and refresh rate (ie 1920X1080 at 60HZ) Most HDTV's have a limited number of resolutions and refresh rates that they are compatible with. When the computer is booting up, it is probably using a default resolution that is compatible with the tv. Then after the computer finishes loading all of it's drivers, the resolution changes to one not supported by your tv

Black and white picture with red lines vibrating with sound.

More info would be nice. Are you using HDMI or Component cables. If it is component cables (red, blue, green for video white and red for audio) Check your red and blue connection. Green alone will give you a black and white picture.
If you are using an HDMI cable, replace the cable to see if this changes anything or if you have another tv swap cables to see if problem stays with tv or moves to another tv.

How can i watch movies from computer to my tv

You probably need to get a composite video output card for your computer. Actually, I've seen many cards that have both a composite video output AND a DVI output port on 1 card. The DVI output will give you a noticeably sharper picture than composite video, but you need to check if your TV has a DVI or HDMI input. (If it was manufactured after 2000, it probably does.) If you TV was manufactured after 2006, it probably has 1 or more HDMI inputs instead of DVI. You can buy a DVI to HDMI converter cable. That takes care of the picture; to get sound to the TV, you will need to connect separate sound cables to your TV. Your computer needs to have a line-level output jack on it's sound card, and you will need to get an adapter cable (from Radio Shack) to convert the stereo mini-plug to 2 RCA type plugs to plug into your TV. And that should do it!

The tv will not see the Mac but I am getting sound on the tv from the computer. Using mini dvi adapter to hdmi cable

Check the owners manual for your TV as you most likely have to change the resolution settings on your Mac to match what the TV will accecpt. Then again there is a possibility they will not communicate to each other. Please take a moment to rate my answer. Thanks..

I just purchased a Sherwood RD 6513 reciever, I'm trying to connect a hd cable box (motorola dch 3200), dvd player (sony dvp ns710h) and a rca hd tv (l32hd41). I connected hdmi cords from both components...

Hi! I will be more than glad to assist you. I f you are going to hook up your cable box - motorola to the sherwood receiver, connect an hdmi cable to the back of the motorola cable box, there is only 1 hdmi output there, then connect the other end to the sherwood receiver on the hdmi input, then connect another hdmi cable to the hdmi output and the other end goes to your rca hd tv.

for the sony dvp, you have only one hdmi out, connect an hdmi cable to the back of the sony dvp if u have another spare. connect it to the hdmi input of the sherwood receiver. there is only 1 hdmi output at the sherwood, so u need to use a component cable to be connected at the back of the sherwood receiver component output then the other end goes to the component input of the hd tv.

if you dont have anymore hdmi cable to hook up your sony dvp, u can use component cable, the connection will goes like this, connect a component cable on the output of the sony dvp and the other end goes to the sherwood component input then connect another component cable to the component output of the sherwood and the other end goes to the rca hd tv on the component input.

I hope this will solve your concern, if you have any question, u can get in touch..

Input 6 - HD Input - Green Screen. Audio Only. No picture.

Hi there,
I am having a similar problem with the inputs. I have a cable box plugged in to cable antenna, DVD to video 6 using HDMI, Mac computer plugged in to video 7 - using HDMI (TV does not recognize this) and then Nintendo Wii hooked up to Video 1.

I have to niw manually switch the cables to have them work...

No owners manual can't get new blue ray dvd player to work on tv

Here is the manual:

When using the HDMI connections you may have to tell the DVD to output to that port.  Also you may have to connect additional sound cables from the DVD output to the TV.

How do I connect my Laptop using the S-video

I am not aware of any laptop which outputs standard or s video without an adapter. You need to get a VGA to video converter. This is the worse image quality that you will get from your laptop. Does your TV have HDMI. or DVI-D. If so get an adapter that goes from VGA to one of those. If you don't have either of those conectors how about component.
If you are using a mac laptop that is a different adapter. Mini DVI to whatever your TV's best input would be
Good luck

you really cant convert to component. it defeats the whole purpose of upgrading your tv. with your tv you should be using hdmi to connect all your devices your cable box should deffinatly have one. any time you connect component to something else you will get black and white hdmi is totally digital where as component is still analog pluse you dont need audio cables with hdmi its just one digital cable

We are having the same problem. We have 2 DVD players with up-converter to 1080i and 1080p. Both DVD work fine (one Sony and one Samsung) with our Samsung LN-T4053H upstairs, never intermittent.

LN40A530 downstairs is having "Searching for Signal" problem. Took it back to Sears got a new one, problem followed. Something is wrong with this LN40A530. Perhaps firmware update is needed.

Blank screen on Digital In

Go into the service menu using the remote (hit the sleep timer, then video status and display at the same time), go into the status menu #2, then power off the tv. This will reset the HDMI port. If your sitll experiencing the issue, probably a dead board.
