What is a service adjustment?? HDMI not working. syncM NG, S NG, RGB NG4, HDMI NG1

you cant record an hd picture and sound through component input rgb,for 1 you arent inputting hd,you are inputting analog,you cant up convert,

Hi Kelly,
I believe the Sony Trinitron WEGAs do not have an HDMI connection on the back of the TV. If they do it would be labeled as HDMI input below that familiar looking HDMI narrow horizontal connector. But I believe what you have is the RGB connector which looks like three round female connectors which are color coated Red Green and Blue. Now these RGB connectors are a form of high definition but it's not a direct connect for for your HDMI DVD player or your XBOX 360 or what ever you want to hook the TV up to.
You'll have to convert you HDMI to RGB. you can still purchase DVD players with RGB outputs but if you already have a device that requires a TV with HDMI, you can buy a converter. Go to RadioShack or BestBuy or search online for a HDMI to RGB converter cable . It should look something like the picture below.
RED GREEN AND BLUE for video. And then the white and red connectors that are banded together are for your audio.
Good Luck

No place to put your RGB on the PC or on the TV? Your TV should have an RGB port for sure. The "green" may be yellow instead.
Your PC will need a video card installed that features a RGB output to make it work from there.
Some PCs use DVI out instead. You would then need a DVI/HDMI converter to plug into your TV's HDMI port and then to the PC.

In order to connect your laptop to your TV using RGB, you need an RGB adapter. RGB is also known as component video; it breaks up a video signal into red, green and blue. laptops do not have RGB outputs. However, many laptops have VGA, DVI or HDMI outputs. An RGB adapter connects the single VGA, DVI, or HDMI cable to an RGB cable, which is actually three different cables tied together. INSTRUCTIONS:
1. Connect either the VGA, DVI or HDMI (in the order of increasing video quality) cable to the VGA, DVI or HDMI port on your laptop, depending on what is available. 2. Connect the other end of the cable to the side of the RGB adapter with the single input. 3. Connect the RGB cables to the red, green and blue ports on the other side of the RGB adapter. 4. Connect the other end of the RGB cables to an available component input on the back of the TV. 5. Tune the TV to the component video input you used through your television's menu. 6. Turn on your laptop. The laptop should now display on your TV screen.

I suspect you are connected by HDMI cables.
Try RGB cables. HDMI can fail to work on some TVs (HDMI is software based and the versions sometimes don't like each other)
RGB is very close in quality and does not have the problem with compatibility.

There are several ways to do this. The two best are:

1. Get a DVI to HDMI cable. This will allow you to plug directly from your computers DVI to your TV's HDMI.

2. If your computer has an analog (rgb (vga) 15 pin) input, you can simply get a dvi to vga adapter and plug into that port.

Currently, I am using option 2 for my own use.

In the photo below, I point out the HDMI, RGB (VGA), and audio inputs. You must use the audio input but you have a choice of using the HDMI or RGB for video input from your PC. If you have the extra HDMI slots, I would use that. If not, the RGB is fine.

This has a failing optical block

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.

try taking out the rgb cable or hdmi cable you are using and put it back in again. if this doesn't work then you may have to get a new rgb/hdmi cable. hope this helps.

Maybe the input on the tv needs to be adjusted to work with the cable tv for example in the tv menu where you can adjust the sources for the inputs maybe it is set to something like RGB instead of HDMI. If you have a user manual consult it on how to change the input devices. Good luck.
