SECTION 6 – REPAIRING YOUR PSU UNIT

If you carefully turn your PSU over and look at the solder side of the PCB, you can familiarise yourself with

where the points are that you will need to unsolder which I have marked for you. Refer to PICTURE 4 below.

At this point you should DISCHARGE any stored voltage from the mains capacitor. As mentioned already,

the stored voltage here can cause you big problems, least of all would be shorting/sparking the unit, and worst

would be hurting yourself considerably. See SECTION 3 above for more information on making a discharging

tool if you do not have one.

Discharging the mains capacitor – The capacitor that will need discharging is the BIG 400v mains capacitor on

the HIGH VOLTAGE side of the PCB. If you have followed the instructions this far, then your unit will be

off, disassembled and you should be staring at the solder side of your power supply PCB. If not, go back up

and follow the previous instructions.

Carefully connect the alligator clips to the capacitor terminals/solder points on the PCB (one clip to each

exposed terminal, don’t short them!). Look at PICTURE 4 below for the location of the BIG 400v capacitor

solder points, I have marked them in YELLOW. Once attached, the resistor will drop the voltage down in

around a minute or so, count to 90 slowly and then unclip and you’re done. Test using a multimeter if you

have one to ensure that the voltage is nil.

Now it's time to replace the components on the board. You will need to replace 18 components in total. The

voltage and type of each component is detailed in PICTURE 1 above and with more detail below where I have

provided MANUFACTURER PART NUMBERS for ordering replacements.

In PICTURE 4, you can see the underside of the PSU board, and as mentioned above I have marked the points

you will need to unsolder, they are in RED – they will match the components marked on PICTURE 1 above.
