Mitsubishi WS-55809 Blue screen on DTV and Component connectors. Think it may be the connectors on Terminal board

DTV is the single HD input for this set.

The model listed has only ONE HD input and it is on the rear and marked DTV--it is a component input with red, green, blue and a red and white for audio---cable box would have to have same outputs on its rear.

I don't think it does since it doesn't have an HDMI input of it's own. You may be better off connecting your Xbox to the TV by component video (Red, blue, green RCA connectors with audio L/R on a separate cable).

I wish that I could be of more help.

I would look at the source for the Hd signal as being the problem--if you are using some kind of cable or sat box it will deliver the signal to the DTV input on the back of the set--this is the HD input for this set.

It is possible to have a problem like you describe be one in the set--but very unlikely----have you looked on that green signal board for any signs of Glycol?

Anything that will produce a 1080 signal to the DTV input should tell you if the problem is the set or the source of the HD signal that is causing the problem.

If the set is normal on AV inputs or thru the coax input--but has problem in the DTV(HD) I would suspect whatever is giving it signal(it is component input) is the problem--the component input for DTV could cause this problem--red,green, blue carry not only video but chroma information---if you are using a direct TV box of some kind return it and get another---only other possible cause(Long shot) would be to do a factory reset on thisTV--All
Mitsubishi sets have an option menu which resets the whole set back to condition it was when new in the box--If you want to try this verify model number to me and I will tell you how to do it--Remember: the set is not smart enough to know which input you are using--if you have a problem only on 1 input--it usually is not the set--it usually is what is connected to that input.

your problem is the 2hdw board is located in the signal board.

On the back of the TV you should find three sets of the component sockets, only one can produce 1080, the one that is labeled dtv (should be the one on the farthest right of the three sets).

Are you trying to use the red/blue green component cable or HDMI cable? You may have to go into the menu on your cable box and specify which cable you want it to output to.

Do the self test located here in threads or ctechnicians.com

Looks like you are going to be working with the following:

 

1080i (HDTV) • 480p (EDTV) • 480i (SDTV)

 

Hook up depends on what else you have connected to the TV.  If you have nothing connected to the DTV component inputs, I suggest using those, as it will allow up to 1080i.  Otherwise, use the 2 other component connections directly to the left of the DTV connections.
