Re: Help with 225BW
I didn't word my question very well.
I have two power supplies. One with bad caps and one without bad caps.
Model IP-45130A: (Bad caps good video board)
States an output: 13V 1.5A for CN2 (power to the video board)
Model IP-43130B: (Good caps dead video board)
States Output 13V 1.3A for CN2.
The video boards have the same part number so i'm guessing the .2 amps difference in power is not a problem but thought I would ask sense there is clearly a difference between the two power units. The video boards...

Re: Help with 225BW
1084-33
If I measure PIN 3 to ground wire 2 from the PSU I show 4.99V
If I measure from PIN 2 to PIN 1 I show 3.3V
On the 1.8 voltage regulator (it's labeled 17 - 18 0721CG)
Pin 3 to ground wire 2 shows 3.3V I'm presuming this is voltage input from the 1084-33?
Pin 2 to pin 1 shows 1.795V
IC501.. To make sure I have the right PN. It's the item circled in red?
If so that PN is Ji7i 78012at4s(?) not sure about the last two digits....Leave a comment:

Help with 225BW
Hi,
First off the help on here is awesome. That being said I think I have a bad component on my dvi/vga board and i'm wondering if someone
can help me figure out what.
I have a Samsung 225BW monitor. The blue power LED comes on but no images is displayed. I swapped the vga/dvi board from a working monitor and an image displays.
None of the caps on the power supply show signs of degradation.
Here is a picture of the board in question.
Any thoughts as to what I should be looking for to troubleshoot this further?
