Attached is a screenshot of various 738 settings and controls. V1 and VR were called called out  and the joystick was pulled back but no rotation occurred. The Flaps 1, D2, assumed temperature are from TOPCAT. V1, VR, and V2 and stabilizer trim are from the FMC. This shot was taken about 1 second after I realized the plane was not going to fly. I have additional screenshots of TOPCAT and the same shot as the one here about two seconds later if they are needed. I see nothing wrong with any settings. However, I could be missing something. If anyone sees anything amiss in this setup, let me know. Thank you.

 

Is trim set correctly,

Check your yoke axis settings. Confirm that hardware settings haven't accidentally disappeared, reversed etc.  Simple Cessna flight will do.

Trim was set at 4.95 ANU per FMC.

That is why I enlarged the SYS Display from Lower EICAS. The joystick has been pulled back for takeoff and the elevators indicate a nose up position.

Bottom left of your screenshot indicates brakes are applied !

 

Check your assignments/calibration. Toe brakes need a null zone. Make sure your elevator axis is not also commanding brakes.

I think that's because he's rejecting the takeoff by this point (RTO):

From what I can see, everything looks correct (trim, power, speed, elevator deflection and other control surfaces), so the only thing I can suggest is a weight or balance issue.

I think that's because he's rejecting the takeoff by this point (RTO):

 

You'd see the white arcs at IDLE on the EICAS if that were the case, I believe.

 

And by that, I mean the outer white arcs that show the difference between lever position and actual N1 (as you normally have when in manual control of the throttles).

Even so, the brakes are something of a moot point since the aircraft has already achieved Vr, so they wouldn't prevent takeoff by this point. I still suspect it's likely a weight and/or balance issue.

Did you load the weight via TOPCAT?

This situation occurs on about 5% of the takeoffs starting around 6 months after I got the 738 in August 2011. For about 2 years it was solved by just pressing the TOGA click spot at idle. No throttle to 40% N1, engage TOGA, full physical throttle. Just press TOGA and go. That worked until about six months ago. Then I started using the procedure per Tutorial 2.

 

The screenshot was probably taken about a 1/4 second after the brakes were applied. That is why you see Brakes on the screenshot.

Did you load the weight via TOPCAT?

No. Loaded per FS Action>Payload. I don't use the W & B page of TOPCAT. I select the aircraft and then go to the Takeoff Off page and enter the TOW from PFPX.

CG within limits?

(CG shows yellow when out of tols)

Nothing yellow on any FMC pages.

I did notice that speed is just below V1 and it is also very hot, +33c, and the aircraft is decelerating rapidly, no doubt due to RTO

The speed is below V1 because I have started to abort the takeoff. Notice that the brakes are on. It was at VR at one time. It hot's because it's Orlando FL at 1:00 PM EDT.

Before you  try this  wait for confirmation  read some where in this forum about  some  thing  about  the fsuipc.ini file  was causing  the aircraft not  to climb, so maybe  this is  the same issue.  If you do delete  this fsuipc ini file  it will rebuild it self on the next fsx load. Any one agree with this or  am iam wrong on this
