Introduction
Reliability and Serviceability Technologies—Simplified!
If one word could be used to describe the reliability and serviceability technologies in Mitsubishi's 2011-
2012 TV products, it would be simplified.

The second generation V42 chassis is a complete redesign of the V40. It is, well... simplified. How?

The Screen is stationary. No motors. No moving parts. No shipping screws.

The Fiber Optic Cables have been eliminated. No optical connectors.

The Mirror is flat.


The Chassis is held in the cabinet by only 4 screws. And, disassembly is simplified by a reduction
in the number of screws necessary to remove the PWB-MAIN. Comparing the base models V43
to V41 shows a screw reduction of more than 42%. The high end models screw reduction is more
than 32%. And the V41 seemed simple!

The Optical Engine assembly has been redesigned to a more compact design and is held in the
cabinet by only 3 screws.

The PWB-BALLAST is held in place by a single clip.

The screw on DVI Cable has been replaced by a finger locking LVDS Ribbon Cable.
DLP Home Cinema

The Self Diagnostics feature is self activated when the set is in the shut down condition. No pro-
cedure necessary to obtain an Error Code.

The Error Code read-out is now color coded. It's now simplified to the point where a customer
can read the Error Code.

Software updates can be performed on-line automatically (Internet Media models).

Bluetooth circuit is on a separate PWB to simplify troubleshooting.
