Thank you for posting your question on Just Answer! I will be happy to help you with this problem. Can you please give us some more information so I can better answer your questions.
-What is the model number for the television? (this can be found on the back of the unit)
-How old is the unit?
- Do you have this problem while watching all different devices hooked to this television? (DVD player, cable, satellite, game counsel, ect.)
Please give me this information and I will be happy to assist you further.
So you have tried the button on the satellite remote but the picture does not change at all?
How is the satellite box hooked to the tv?
How do you have the satellite box hooked to the tv?
The choices are:Component cables: 5 wires between the tv and the device, these are color coded on the end and have a green, a blue, a red, a white, and another red cableComposite cables: 3 wires between the tv and the device, these are color coded on the end and have a yellow, a white, and a red.HDMI: 1 wire between the tv and the device, this is a single wire and looks like a computer plug on each end, similar to a large USB connector.Coax: This is 1 wire between the tv and the device as well. This is the normal cable wire with the end the screws
Those satellite boxes update randomly, whenever the satellite compnay wants to change something so it is possible that we have a conflict issue though HDMI...can you try hooking it up with component cables real quick to test and see if the problem goes away?
Still no adjustment at all when you try to change the aspect?
Question...can you change the format when you are on dvd and make it bigger and smaller?
Lets try to preform a factory reset on this set...
Turn the tv on and then use the Mitsubishi remote to press the following buttons in quick order:
You will then have the OPTION MENU on the screen, scroll up or down to highlight Initial and then press enter on the remote.
Does this help the problem?
So with the mitsubishi remote you cannot change format either when watching dvd?
Well I do not see a reason why this would be unless the main board in the set has failed...The problem is this is about $500 to have replaced. I am sorry for the bad news, I was really hoping for a quick fix or a easy adjustment but it appears that the signal board in the set will need to be replaced at this point.
