RCA DRD430RG

Mike,
 I found this with a "Google" Search...

"I have the RCA DRD430RA Receiver which is putting out 21 volts to the
LNB, instead of the proper 13/18 volts.  This is causing the receiver
not to receive signals from the odd numbered transponders... now...

I am no genius when it comes to fixing electronics, but I know some
basics.  I have traced the center pin on the coax connector back to
the power supply board, and found that it goes to an LM358 Op-amp.  I
figure this is controlling the voltage to the LNB, and I believe it is
bad (BAD LM358, BAD!) :-)

But before I start soldering, I would like you experts 2nd opinion.
Here's the voltages at each pin relative to GND:

1.  ~10mv
2.  9
3.  5.7
4.  GND
5.  17.5
6.  16
7.  19.3
8.  20.8

It looks to me that the "A" side of the Op-Amp isn't functioning,
hence the nearly 0 volts on Pin 1.  Do I have this right?

I guess I don't understand exactly WHAT the op-amp should output based
on the inputs, but I would think zero isn't right!?!?!

The "cure" below..

Looks like I'm talking to myself again :-), but the fix worked!

The transistor is an NTE55 type, and is the one on the heatsink in
approximately in the middle of the power supply board.

Enjoy!
