PS3 Lost Back Up Light

  If you open the engine, pull the 40 pin connector and re insert back in.

pull the 40 pin connector and re insert back in.

Very gently and not by the wires!!

Pry it up slowly and incrementally from the ends of the connector!

Check and make sure none of the pins are even slightly bent before you reinstall The plug. 

Check the the wires to the backup light for pinches or missing insulation. 

Thanks all. Will report back later tonight or tomorrow once I get it open. Will try the plug first. 

Any idea on what may cause this? Is it a "known issue" or is there an issue with the engine? 

You are saying it worked properly on a recent DCS test, but not on a later conventional test?

When you take off the shell see how it is connected.  If plug make sure it did not push pins out of female connector.  Make sure wire was not pinched under shell.

If connected via the spring pad method make sure the connector did not push out and the springs length is good.

The real goal is to find out the LED still works.  Using a 3 volt source or a  higher DC source with a limiting resistor to test the LED.  Polarity matters.

While LED last longer, you can have a manufacturing defect and early failure on some.  It happens.

Or the LED is good, and it is the wiring, connector, or possibly the 40pin contact as mentioned by Marty.   G

G, 

That is correct. No issues until yesterday. 

I popped open the shell earlier and didn't see an obvious 40 pin connector. Saw what I thought may be it but there were so many wires surrounding it, etc that I opted not to screw with it. Since it is under warranty, I boxed the engine up and it is waiting to go to the LHS tomorrow.
