Re: no video from rgb inputs

Usually this is a bad connection on the system board, cable, etc.  If it's not under warranty, I would check the cable first, and try multiple video sources before opening the unit.  Worst case scenario is replacing the system board where the connections reside.

My question is where is the cable connection on the ALT3213om model

Not all models have cable inputs, if you don't readily see a cable input, you will have to use the RGB inputs or composite input. You may have to acquire a converter to convert cable to RGB or Component input.

How to connect dvd player to LG RZ-32LZ55 in LCD TV

This 'TV' is really more of a video monitor. It has one DVI input, 2 SCARTS (1 RGB); component video input; composite video input; S-video, and stereo audio and RF inputs. Best picture would be using the component inputs if your DVD player has the outputs. If not you'll have to consider the S-video or composite (yellow) plugs. (Neither is HD capable....)

I plugged in the normal 3 Video inputs and it still doesn't work.

More info is needed, please. When you say 3 video inputs, what are you referring to? I believe the Sanyo has the HDMI, RGB/YPbPr component video, S-video component, RCA composite video and Coaxial connections, though I'm not sure how many of each. So lets start with the best quality to least.

HDMI: This is one cable that provides both audio & video and produces the best picture quality. It comes in different lengths and is a wide, flat connection. A must for 1080p resolution signals.

Component video, RGB or YPbPr analog component cables: 5 separate RCA cables, 3 of which are video that separate the video signal & 2 audio cables. The 3 video cables are generally red, green and blue (RGB) or marked individually with the letters Y, Pb/Cb & Pr/Cr . The audio cables are red & white. You may see these on the back of DVD players often. They will carry a signal up to 1080i but not 1080p.

S-video component: One cable for video, it is a round connection with several pins in it and will only plug in one way. You must use 2 RCA cables for audio with this cable, red & white again.

Composite video: 3 separate cables; Red, White & Yellow. Red & White are audio, left and right while yellow is video.

And finally there is coaxial which it the cable that is identical to the cable from the pole/ cable box or your dish. It is the poorest quality.

What can happen is you are using 3 standard RCA cables and have them plugged into the component input & they will not carry the signal, or one end in component input and the other end in the composite output or vice versa. Another is that you have the wrong input selected on the menu. Check all your cables and connections, plus the input you have selected on the TV itself.

Need the manual to find out how to setup AV3 & AV4 as Component input, or if it is compatible with standard component input. Does not seem to work

Well, lets start here first. I would like you to look at the input jacks for a/v3 and a/v4 and see if they are color coded RED-GREEN-BLUE. or if they are just YELLOW-RED&WHITE (audio). If they are RGB then just buy RGB cables at your local Best Buy. If any are just Yellow and Red & White then those are just regular composite video the same as the old vcr's. You can't make A/V jacks work like RGB component jacks.

What type of audio jack rgb/dvi in on rear of lg 50ps3

the dvi out of pc via adaptor to hdmi on tv has no audio,ok.
so LG diagram shows separate audio into Audio in RGB/DVI.
Resulting in video in on HDMI ok,but audio on RGB.Can not get both together.
Fix is revert to DVI to RGB lead with audio on RGB/DVI input.
The audio jack would only work with mono plug for audio in, to RGB.

RGB port

A VGA & RGB port is the same thing. RGB is Red/ Green/ Blue for seperate input & VGA the video graphics array which does the same thing.
A DVi is an entirely different type of input port for digital input where your VGA port is more for analogue type inputs
