OK, my bad!! I decided that AC voltage at those resistors seemed fishy and both the fuses on the same board with the 2 resistors blew at some point I guess... Now I know what gives if they blow again. Replaced them both and were back to where we were before. So..... We left off looking for DC at connection CN34 , all 4 pins. OK I get 5dcv on 3 and 0 dcv on 1.
In this order.....5,5,0,5

Which 2 fuses blew? The 2 on that board AWZ2893 that also has the 2 resistors you were testing on, R122 and R123?

Did you also check the 2 fuses on the next board that the J11 harness is connected to, AWZ2894?

At this point you are going to have to do some testing right on the front display. So you are going to have to remove the front and take it apart down to just the board and then be able to connect the ribbon cables back up to it. Let me know when you are at this point and I will tell you where you have to test.

OK, need a bit of advise about 2 connectors I'm not 100% sure on how they come off. I got the other connectors out ( the white ones from previous pic) but these again are a different style....   |

Picture is to dark. I cannot see what the sides of the connector looks like.

Try this one...  It's the grey connector.... |

That looks like the style that the top piece of the connector pulls up about 1/4 inch to release. See the slot in the side. But it must slide over the cable insulation. It looks like it might catch the edge of the insulation in your picture. The cable wont release until the connector piece is all the way up. Let me know if that does not work.

I got it.... The sides just pry out and connector top comes off and wires can be pulled out... Got to desolder a few grounds and I will have it completely removed.

Do you have the board reconnected so you can turn it on and make some tests?
