2007 Multifunction Display fading.

Looks to me a bit like what you get with polarization. Perhaps thereare 2 screens over the display and one has somehow gotten twisted. Someone with more sense than me will possible answer your question later, but that's all I can offer.

 

maybe a loose connection? or just a defective screen that needs replacing.

 

No back light or it move out the it holder

Looks like you need to buy a replacement MFD; remove the original so that you can determine the correct part number, and look on eBay for a used unit.

 

I have the EXACT same issue.. Same 2007 Prius.. And also live in Florida.. Would rather not have to buy a whole new MFD.. Any way to just change the screen? Or clean it?

 

Do you have a picture of it? Mostly a Capacitor

welcome!
i don't think cleaning is gonna help, but give it a shot before buying a reman on eBay.

 

I also have the same problem with my screen on the MFD. Did you find a solution to this? My current assumption is that this is being caused by sun damage to the screen. I also live in Florida and I noticed that the screen darkening started after my A.C. went out. I drive with my windows down a lot causing the MFD to be in direct sunlight. I know there is a polarized filter in front of the screen and I wm wondering if it can be replaced easily.

 

You need back light to see the screen like a led tv. It normaly a light on the side of the screen either the light gone out or it not in place

If it is sun you just need a new dark tint. Filter (window tint) you can tell him dark of time by the the spot that still works a little lighter. I think you back light out on one of the side of the screen kind like dash lights but on the side

it looks as if it's gotten too hot, what temperature weather do you live in? Probably best just to replace the unit for a cheap used one on eBay

 

This is what our 2006 screen looks like...just not as dark. We spent many years in south Florida before this happened. What have you done to repair it? Is it a backlight? Or, has the screen been sun damaged? What have you done to remedy the situation?

 

I have a 2005 with the exact same problem. I thought that it might be the digitizer screen, which controls the touch screen function, and which is the least expensive to replace, so I dismantled the MFD, and replaced it. Although it did improve the viewability of the screen it did not completely correct the problem. It appears that the main culprit is the units LED which sits behind the digitizer. I believe the best alternative is to find a good used MFD. The dismantling of the MFD to replace the digitizer is time consuming but can be done with patience. The biggest problem in removing the MFD was removal of the A/C vent covers which were so brittle with age that they all broke when being removed, regardless of how careful I was.

 

It seems this is a common Florida Problem I am going to change out my digitizer this weekend to see if it resolves the problem if not i will begetting a reman unit to replace the whole unit

 

I had the exact same issue with my 2009 MFD. The Southeast heat must’ve fried it. Bought a used one from EBay and swapped it out and it’s alive again.
