Power supply

Hi,
   I've 2 toppy's for may years, one of which now looks to be foobarred. Without a HDD it looks to work ok, but if I put a disk in it doesn;t spin up (I've tested them both in PC's and they work ok). I've had intermittant problems with it losing all the channels and failing to see the hdd on startup. I've read on here about the jaycar caps and I'd rather not use them, Warkus do you still have any of the better quality ones available?

cheers

Dave

I ordered the same caps as Garyvx did from Farnell a couple of months ago, 2 sets, $22 delivered next day.

From his post earlier in the forums...

The Caps I replace are C22 with http://au.farnell.com/panasonic/eeufc1c222/capacitor-2200uf-16v/dp/9692088
And C23, C17, C18, C19 and C25 with http://au.farnell.com/panasonic/eeufc1c122/capacitor-1200uf-16v/dp/9692070

Hi Dave
I've done quite a few CAP replacements here in Melbourne and I'm about to order another set for someone else.
Are you going to do the replacement yourself?

Regards Gary

Should take you under half an hour to have it back up and running.

Just make sure you take out the right ones, and take note of the polarity of the 1 that you remove.

There is a line down the side of the capacitor, the replacement has to be on the same side

Its not that difficult a solder wick will help remove the old capacitors.

Dave,
The mains power has a symmetrical RF filter and a full bridge rectifier so in terms of actually working, it will work the same regardless of which way around the 2 pin mains plug (well socket to be correct) is inserted onto the 2 pin header on the power supply board, however while it will work properly with the main plug either way around, by rights the active should be connected to the pin closest to the end of the circuit board.  The "active" is a brown wire and the "neutral" is the blue wire. By having the mains connector positioned with the brown active to be closest to the end of the circuit board, means it connects directly into the 2 Amp fuse next to it so if anything on the mains side should short to the chassis the fuse should blow as the mains pin closest to the end of the board connects directly to the fuse, whereas if you had the other way around there are several places where the active could short out and not have the protection of the fuse. Worse is with the mains connected backwards, if the fuse did blow for whatever reason there'd still be 240 Volts throughout the power supply even though the unit would appear totally dead, compare that to having the brown active wire connected closest to the end of the bed, if the fuse blew, the only live component is one end of the fuse holder.
