I believe this is you power supply board manufacturer and number. http://erecycleronline.com/planar-po...r-monitor.html

I think this one is as close as you will come to your. Perhaps ypu can contact them and they can help you. http://www.shopjimmy.com/planar-433a...t-inverter.htm

Since you do have 1000uf 10V in place, then the positive leg of the 1000uF caps should be connected to one end of the Inductor (Round inductor with black shrink tubing which is part of the Pi filter network), another end of the inductor should go to the pad where the 470uF 10V cap should be. Your board look to have 3 inductors for Pi filters for 3 power supplies.
Good clear straight shot pictures of the bottom side of the board will help a lot.

I circled the 2 that i don't know what they are. Also circled the negative pin hole. Which are 5 and 7 on the front pic. The bottom one is #7
You all have been great with helping me, Thanks alot

Do you have this picture without the red marking so I can do the tracing? BTW, the picture of the bottom side is really dark that I cannot clearly see the circuit traces.

I was thinking if you contacted them and told them your problem they would give you the information on the caps.

I hope you can follow it better now.

Cap 1, 2, 5, 6, 7, 8 should be the same Voltage rating

Cap 3, 4, 9 should be the same Voltage rating.

i don't have a 9 drawn on the front pic. U mean the one still in place on the right side of front of original post picture is 9? that is 470uF 10v. 3 and 4 are 1000uF 10v. i just need #5 and #7. one should be 470uF 25v the other 470uF 10v. those are the 2 caps i have left that i can not place. Here are pics before removal

#6 and #7 are connected in parallel so they are have the same rating, these two caps should 820~1000uF 25VDC since they are for supplying the Voltage to the inverter circuit. What is the value of #6? If #6 is 470uf 25V, that will be too low of the capacitance for that section, if that is what they used (470uF for 6 & 7) it is more likely to be marginal.
#5 to be safe, you can install a 470uF 25VDC cap then take the DCV reading, if it only has 5V on it then you can use 10V cap.

BTW, #3 and #4 (for the 5V) are also connected in parallel, so they should be the same rating.

Re: Need help where Capacitor goes Hanns hw191D

After comparing the pic in last post that shows 3,4,5 i compared the lettering at the top of the cap and it compares to a 470uF 10v that i have left over, and 7 would be 470uF 25v for the last leftover.
