Re: sound but no picture

Everyone - this happens to EVERY LT30Hv, and is fixable despite what the **** idiots at Syntax. They are not a TV manufacturing company, they are an import/export holding company with a freaking LOUSY website. This is the part you most likely need. If you can work on a computer, you can probably fix this yourself. I'm helping everyone I can help with this to shove it down Syntax's throat. I am in the midst of performing and documenting my second repair of this same procedure, and will post on Flickr when I can get it up.

Olevia 242 TV.... No picture or sound!!!

A blue screen usually is present if no signal is connected to the set---hook a DVD up to one of the rear inputs--select that input and see if have picture and sound.

If that works connect cable or antenna to set and select that input

NO signal is like no gas in car---it will not run.

I have 60inch plasma tv. the power is on an the blue light,but no sound an no menu or picture.can you help me pls?

Please cycle the unit through the various inputs to make sure it is on one with something hooked up to it.

Either that or a defective cable someplace--double check the hookup and start with just a DVD or something connected to a single input to see for yourself if any input is working.

The inputs are of course different from the cable fitting and it is possible for the tuner in the set not to work but the rear audio/video inputs to work.

Let me know what you find.

Need to hook up LG tv to phillips cd/4 head hi fi and RCA surround sound

Ok: I will guide yourself through "hook up" process.
1. connect your TV set to your VCR, using 3 wires RCA cable(Yellow, red, white) to "Video1" input, yellow only! The other 2(sound channels) connect to "home theater/DVD unit. Use "aux" input.
2. Connect your DVD video output. yellow or 3 colored( green, blue, red) component cables to your TV's Video 2 or "component 1" input.
Now you'll be able to use your TV as a video monitor for your VCR and DVD.
The sound will be handled by DVD/Home theater. In case your TV is a very modern, all you can get out is: direct digital sound stream. Your home theater must be equipped with coaxial(orange) input(looks like RCA plug) or optical input. Or both. You must use proper cables to connect TV to Home theater.
sorry, but it requires some patience and thorough reading of user manuals.
Otherwise, it's "level 1" difficulty. nothing you may damage, due to installation.
Good luck,
Feel free to ask for more help, if needed.

I have a memorex dvd player and a dynex 32" lcd hdtv. I have all the cord correctly in the component plugs but the picture is black and white and there is no sound.

i think ur component video connection may inter changed. check it. are u connected red to red, green to green an blue to blue. if interchanged the picture will be black and white. also check the video system of ur tv and dvd.
about audio. for that u need a stereo rca chord. connect the audio output of ur dvd to the component audio input of ur tv. if u have already connected the audio cable , check the audio setup of ur dvd. there is selection for pcm audio select it and then check again.

I have a samsung2333hd and want to connect a dvd player using the connections marked pr(red) pb(blue) y (green) when i connect them all i get a redish pink screen then when i connect two of them i get...

OK no problem here. I can help. First reconnect the DVD Player to the tv using the Compoment cables. Match Green to Green,Red to Red and Blue to Blue.. If this is done correctly then you will have normal looking picture. If the picture looks like it is missing the RED color then switch both Red cables. The pix should look normal. Then connect the RED and White audio cables to the audio inputs . Now the Pinkish color is a result of the DVD Player not being set to the "Progressive" setting in the DVD Player Menu. It will help to connect a set of COMPOSITE cables from the DVD Player to the TV's Composite Input. Those are the Yellow,Red and White inputs on both the tv and the DVD Player. This will allow you to see the DVD player menu in case you cannot see the menu while in the Component input. The Pinkish picture should go to a Normal picture.
