Hitachi 32HDT20M Plasma Monitor

Here's some tricks I would try. Something here, might help...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

RGB is a term that means the guns in the crt or other display are only driven by amplifiers for that color. So you have to have seperate signals and inputs for red,green and blue. Those come from the source in that method. They are then fed into the monitor for which each of those colors has its own channel and amplifier. If you dont have something that is supplying the RGB singals then it is of no use. The colors that you listed as red white and yellow are for COMPOSITE video with AUDIO. The yellow is the whole video signal and the red and white are stereo sound signals. No attempts at making that work will correct this unless you buy a converter.

This TV has both Composite (Red, White and Yellow) plugs and Component (Red, Green, Blue). Either are acceptable solutions, although ideally purchasing an after-market Component Video cable should yield the best possible picture quality.

Yes you can. Simply connect the appropriate color inputs.

If you use red green blue for video, and red white for audio you will get the best picture

If not stick to yellow for video and white red for audio

Just remember color that is on the back of dvd goes to same color on the input for the tv

I dont have a solution but I will purchase your AVC-50 audio video box when your ready to sell it. Please let me know, I really need one!

Replace your buffer boards they are two unit located on the right of the plasma if you are looking the plasma from behind. Do you have any sound?

Thanks,

Sorry I know your model number and its a Power Down trouble with the Scan IC's that are in the unit. You need a tech to look at it and he will most likely find a bad Scan IC and it will need to be replaced. This a is a relatively easy fix for him.
