Information Breakdown...

 My Rx, Monster Truk, has an information breakdown...  It's an electronic component thing.  Electronics work best when they have a solid state condition, and are completely isolated from mechanical movement.  Well, some electronic components are mechanical constructions, and are still vulnerable to motion, and will breakdown with vibration.  Anything that is mechanical, and moves, will breakdown faster than solid state components.  In this case I think it is capacitors.

OK, lets extract the component that is in question, open it up, and look for some signs that we have failing components.  First we have to get the component out of the assembly in which it lives.  My RX is a Toyota product, so we have to deal with the interior constructions of a Toyota product.  First we need to pull some trim pieces out of the way...

The first piece you to get out of the way is the faux burl wood trim piece.  Looks neat, and does nothing...  It is secured with plastic clips around the perimeter.  Use a plastic trim pry tool to gently remove this trim piece.  I used my Mini Bar to get it started, and very gently indeed...

I am surprised at the amount of debris that is behind the things that I am removing.  So, there were a few electrical connectors I had to remove from the trim piece.  Next we can remove the four, ten millimeter screws that retain the radio, and the the upper part of the center console can be removed.  There are a considerable amount of electrical connections on the back side of the upper part of the center console, but they are all unique, and only go back into a singular location.  This make it much easier to reassemble.

OK, now, carefully, we pull off each connector, being very careful to not damage it, in order to liberater the center console facia from the vehicle.  Each connector has a latching tab that must be depressed in order to disconnect it from its mating connector.  When all the mating connectors are detached, then you can pull the Center Console Facia away from the body of the vehicle.

Now we can start to disassembly the upper center console, and isolate the display so that we can diagnose the breakdown.  Toyotas are very modular, and they have dedicated divisions that work on these individual parts.  Every sub-system in a Toyota has a dedicated subdivision of people working on that system.  In this case I have a multimedia display, with a touchscreen which has a fundamental breakdown.  The display, and touchscreen are contained in a module, with a part number, and you can go find them on the interwebz,,,

Here is a shot of the liberated Display Module.  You can search on the Interwebs to find this specific part number, and haz yourself a new display.  I'm gonna say that I am a little more adventurous, and I am going to troubleshoot this module down to failing components rather than just replace it. I might save a couple bucks, but, ultimately it is the knowledge of circuit failures is what I am after...
