Diode test results show reading both ways

Re: Diode test results show reading both ways

The info below is another posting by me at https://www.badcaps.net/forum/showthread.php?t=59414

I started this posting because I didn't get a response about the diode issue there, and thought is was important....

There's no standby led lighting up. Without the main board connected, I get 5.14 on the 3 pins labeled for 5v for what I assume is standby(con isn't labeled as such...see pics). With main board connected, I get the following pin voltages:

1 gnd
2 5vcc 5.21
3 5vcc 5.21
4 gnd
5 5vcc 5.21
6 13vcc 12.71
7 13vcc_AUD 12.71
8 gnd
9 PWON 3.03
10 ACD 3.46
11 gnd
12 BLON 0
13 DIM 0

I realize that pins 6 & 7 are supposed to be 13v. I don't know what pins 9 & 10 should be, nor 12 & 13. Also, when checking diodes and fuses, I found that D210A on the Secondary side has reading both ways (208 and 1342) I keep running into this, and am wondering if this is normal on the secondary side, or not? I usually don't take the diodes out of circuit when I test them...maybe this is why I get this?

So the main board is sending the PWON to turn on the rest of the power supply but it is not sending the BLON or DIM control signals.
Bottom line: it has nothing to do with the diode you were testing. Your main board is the problem.
When testing diode and it shows conduction both ways, I always need to know the resistance reading.

Re: Diode test results show reading both ways

Your power supply board is putting out as it should as shown in other thread in the TV section, this thread should be closed.
Main board problem as replied in other thread.

Ok, budm, I understand. I've never closed out a thread, so not sure how.
