I suspect your fault is a common one and the convergance ICs have failed.
Is it showing any error code and have you tried entering the self test mode?
Turn the TV Off and let the Power Light go out
Press and hold both the Menu and Input Buttons on the front of the set at the same time for at least five seconds and release both buttons.
Power light will blink an error code. The most common is 2 blinks, 2 blinks, a pause, and then repeats several times.
Please let me know what you find.
This is the no error code. What inputs are you using for your DVD & Satellite?
I think the first thing you need to do is to reset the Inputs to the Factory Settings.
Have you many many or any changes to these settings yourself?
Do you know how to do this using the individual Input Menus or to reset all Inputs using the A/V Reset on the front of the TV.
Sorry but something I should have ask earlier is this something you've just set up or have you had and used it in the configration for a while?
I suspect the fault then is with the DM Board although I'm having difficulty finding a service manual to confirm if this would need a total replacement or if it could be repaired.
Would you have the ability to repair a PCB yourself by removing and replacing components?
What feedback are you getting from your other expert?
The only things I've been able to find relate to a faulty diode D2553, dry joints or broken track on the DM Board so probaly worth pulling it out and checking the capacitors while you've got it out.
OK but make sure you check for any dry joints or breaks/damage in the PCB track.
OK, I appreciate you keeping me informed how it's going. What Diode was it?
Thanks, let me know how it goes.
I'm begining to wonder if your problem is with the outputs rather then the inputs on your TV. Is it the same on all 3 component inputs?

Try to check the PAL,NTSC setting set it to Auto. feel free to send feed back good day and best regards.
The tv works perfectly, even the 12 code tells you that. Your problem is in the connection between the sources and the tv - something is wrong with the cables or the way they are connected. Most likely the S-video or the Component cables are either damaged or incorrectly plugged in.
Use the RCA INPUT connections 1 and 2 (the yellow, red and white ones on the left): just pair them with the similarly coloured output connectors from the satellite box and the dvd. You won't notice the difference in the image quality if you use decent cables.

After holding down the DEVICE and MENU buttons for five seconds I got the following ...
One blink, two blinks, then a pause.
Turned off TV. Held down Menu and Device buttons for five seconds and got the following indications.
1 blink, 2 blinks, a pause, and repeat several times.
DVD - Component 1
Satellite - DTV
I've used it in this configuration for a while. I deleted the current configuration and rerun setup. I also pressed the A/V Reset button on the front of the TV to no avail. I'm still getting a fuzzy black and white picture.
I feel comfortable repairing a PCB board and removing/replacing components. I have not received any feedback from another expert.
I've replaced the capacitors so I'll check D2553 next. It'll take me a little while so I'll probably get back to you tomorrow.
I found a bad diode on the DM board (not D2553). I have a new one on order and should get it by the end of the week. I'll solder it back in and update you then. Thanks.
D9801 on the DM power board.
Cables are fine and connected correctly. They are monster cables and I've been using them for years without a problem.
Finally got a replacement diode with no luck. Same result. Will look around for D2553 and test it. I'm guessing that it's on the DM board itself and not the DM power board?
More troubleshooting and playing with it led me to find out that only the inputs with RGB (component video) inputs aren't working. The video from my VCR (yellow RC jack only) works fine. When I plug in my DVD and Direct TV into that input they work find as well.
It's working now. Not sure how I got it to work. Maybe cable configuration (I've unplugged and plugged it in several times) could be that it just got a reset somehow. Anyway, it's working now so thanks for all your help.
