Hello out there, wondering if anyone has a circuit diagram for TRF-7160 power supply, trying to ascertain the value of a blown resistor, thanks

There may be something on the oztoppy wiki - hae not checked for a long time.

Many thanks IanL-S, I'll check this out, otherwise I'll try to find a similar machine and read the color coding from it's board

Haven't been able to locate one of these to check the colour coding on the resistor. If one of the members has one of these boards (model AD09026T 27/10/2009), either a photo or the colour coding of the R7 resistor would be greatly appreciated, many thanks

My 7160 has a different power board altogether.  Actually, the power board of my 2460 looks closer, but is still significantly different.

You should try posting this question on the European forum, there are a number of users that are knowledgeable when it comes to the hardware.

Also, what model number is on your main board?  Perhaps there are other PSUs that suit that main board.  My 7160's main board is "TRF-7160  Rev 3.1" "P000-1F716-431-0"

Thank you DeltaMikeCharlie, the main board is TRF-7160 Rev 2.1 P000-1F716-421-0. I'll try posting to the European forum.

Hmm, does this mean we should be taking photos of working boards in case a component burns out? lol

Should we start a hardware documentation project, possibly in cooperation with the European forum?

We could start by taking photographs of power boards and main boards of various models and revisions and store them in a central location.  Users wishing to repair units, could use the photos for reference and comparison purposes.

Also, perhaps a "Register of Dead Toppies" could be established for a type of organ donation system.  If someone's faulty PVR is retired after years of faithful service, perhaps some of its remaining inner workings could be valuable to others.  Perhaps two dead PVRs could be stitched together to form a single working one.

I suggest that the only rule would be that the receiver pays for shipping.

I make a habit of taking photos of main board and power supply of all my Toppys. I will (when I get the time) post them on the oztoppy wiki.

Hi All, unfortunately the power supply went to God; however if anyone would like the main board (TRF-7160 Rev 2.1 P000-1F716-421-0), the HDD (500GB WD) and display board (RAU88F881), I'm happy to pack and post (at your expense), regards Rob

Saw this thread a bit late. Out of curiosity the R7 resistor is L-R brown, black, red, gold.
My 7160 has the same power supply and mainboard. I'd be interested in your left overs
as spares. Sent you a PM.

Thanks,
James.

IIRC the colour coding for resistors that would make it 1 0 00 ohms (1k ohm).
Looking at the picture of the power supply, the appears to be a bulging electrolytic capacitor that may well have been the catalyst for its demise.

A register of dead toppies sounds like a good plan to pull a Lazarus.
I have a perfectly good 2460 that is looking for its main board (I killed it wen trying to refloat the SOC).
