"Service not running or scrambled" has been intermittent for a while on my TPR-5000

Previously it's fixed itself after some cursing & swearing, together with powering-off at wall then trying various channels until one decided it'd work, after which all worked

Not this time

Seems there are multiple theories about root cause for this, and after a couple of days trying every channel, I decided it must be hardware and opened it up to check out capacitors

Seeing all electrolytics were 85° rated, I replaced most of them with known 105° Japanese makes, before running out of replacements

Left the others alone, assuming they're reliable polymers

Decided to give it a try at that point, still "Service not running or scrambled"

I've decided it's not a genuine problem because TV has no problem with reception, getting its signal from the TPR-5000's Antenna Out - also no problem if I simply plug the Antenna In cable into the Antenna Out cable, instead of both into the PVR

So I decided to try the firmware theory

Mainboard is TRF-7160 rev 2.1 P000-1F716-421-0, system status:
System ID    32340
Loader ver    1.02
Device ver    1.0.1
App ver        TF-BCPF 1.01.00

Unfortunately Topfield did a pretty good job of stopping TPR-5000 from being updated with firmware from other models

From a USB key I've tried many of IanL-S's TRF-7160 & TRF-7260 firmware downloads, all getting rejected as wrong ID

Also tried unsuccessfully the bricked Toppy recovery procedure

So now I'm stuck

Having reset to factory settings, only options now seem Station Search or Firmware Update, former finds nought

Somewhere along this journey I recall mention of repackaging firmware for a different model, but cannot find procedure

TL;DR need firmware for TPR-5000 - could someone please provide same, or how to repackage other firmware acceptable to TPR-5000

The original firmware is available at the follow link

Here is the procedure to extract and change the system id. I have no experience with this so no liability accepted.

Thanks James - hopefully I can now recover with original firmware if wheels fall off

Although my experience with Bin2TFD wasn't as stellar as I hoped - TPR-5000 firmware update accepted file produced by Bin2TFD then produced message like "Failed to read/write file"

Maybe not surprising when you see size of Bin2TFD's output, latter of the following:

07/09/2018 09:57 PM     9,516,200 TRF-7160_32027_v1.08.00_2012Sep14.tfd
09/09/2018 04:27 PM 2,147,516,207 TRF-7160_32340_v1.08.00_2012Sep14.tfd

I guess I upset its applecart by using standard .tfd file as input, rather than binary firmware image I assume it expects, judging by name Bin2TFD together with instructions for copying firmware image from PVR's file system

I'd appreciate if someone could advise how to extract firmware image from a .tfd (using a hex editor perhaps), or even better, supply a prerolled late model .tfd for the TPR-5000 [wink]

I have an a 7160 firmware that I ported to the 5000. Also tried the 7100+ without much success, but that may be IceTV related. In my case for some reason the front display is scrambled. As I only use the 5000 as a backup it is not a big worry. Otherwise it seems to work OK. Could possibly be fixed by resetting to factory settings.

You can download repackaged 7100+ firmware from here and 7160 firmware form here. One advantage of these firmware are that they support quad recording and include TAP support.

Thanks IanL-S, you've saved me a lot of effort

Both firmware installed on my TPR-5000 without issue

Unfortunately seems as though "Service not running or scrambled" is a hardware problem in this case - neither firmware made any difference to the outcome from Station Searching, still nothing detected

At this point I think I'll agree with a theory I read somewhere about faulty BGA connections beneath the main chip, the one with the heat sink on it

Seeing main board is labelled RoHS (= Restriction of Hazardous Substances = Lead-free solder) that theory has a lot of plausibility

I've attached pic of main board in its original state, in case anyone's interested

TRF-7160_bef.jpg 

Capacitors I replaced were certainly held by some weird solder - much effort required to remove, solder didn't melt like normal, even compared to more recent computer motherboards with which I've worked

So TPR-5000 and I have reached a stalemate, until I can work up enough enthusiasm to have a go at the main chip with hot air station

My dilemma is what to get now - once upon a time I'd have gone for Panasonic without qualm, but judging by most recent acquisition, Panasonic are trading on a reputation which is no longer warranted

Currently considering a cheap Wintal STB18HD = Radio Parts house brand ? - any feedback on this ?

Why don't you try and purchase a new mainboard, even a genuine 7160 board. There is a guy on the forum who bought all their spares when they quit the country.
I think his username is - fixmydata

Thanks again James - worth finding out if that's an option, so I've PM'd fixmydata

My mother got a Panasonic PVR a few years ago. It was crap. So awkward to use. I don't think it was significantly worse than many others on the market at the time. That was why Topfield was so successful - it was easy to use.


A lot of people looking to replace Topfields are looking at Beyonwiz.

The Beyonwiz is the obvious choice. There is bit of a learning curve, but once you get the hang of it you get a good experience. If you use IceTV it works much, much better on the Beyonwiz.

Being of a certain age, and having used Toppy for a long time, I do most of viewing of recordings on my 7100+ or 2400. (Usually transfer them from Beyonwiz - the U4 has 10x ftp speed - edit them, create *.nav with TFtool, and send them back to the Toppy by ftp.)

Yeah,we have had a few in the extended Family over the years,mine was the first model,2008 DMR-500BD but MPEG2 unfortunately.It is still going and comes in handy to transfer FTA Rec. to BD or DVD.
I agree it was clunky to use but super reliable,no bugs,it just worked.
I don't see the point in wasting time and money on the MPEG 2 Toppies,time to move on,you can get a MPEG4 model that does HD for next to nothing and worth spending time/money  to get it going.

The TPR-5000 is a MPEG4/MPEG2 PVR - it uses the same main board as the 7160. Aside from the case, the main difference between the two is one is branded Toppro and the other Branded Topfield, and on supports quad-recording and TAPs and the other does not. I prefer the case on the 5000 to that on the 7160.

My father-in-law had a 7160 which I had recommended and which he used for years. Then one day he rang me to come around and set up the new Panasonic PVR he had bought because "the Topfield didn't work anymore" (Grrr, why didn't he ask me about any of this first!). The new Panasonic was an absolute pain to use but I set it up and showed him the ropes.

I found the only problem with the 7160 was a broken remote. Someone had seemingly stood on it and broken a capacitor off internally so I soldered it back on and it worked fine. I told him if he gets sick of his Panasonic to call me and I will put the toppy back. He lasted about a month before calling me.

Radio Parts show Wintal STB18HD at $69-95, so, after finding CatchOfTheDay.com.au offering it for $57 shipped, I took the plunge

First impressions:

Trivial to some perhaps, but to me a real pain was its large moulded power plug, especially considering it's two pin

Had to pull other stuff out of cabinet, then use file to enlarge hole through which other plugs fit without issue, before I could even connect it [mad]

After that, at least it did power on, and its Search found digital channels [thumb]

Plugged in a re-initialised 1TB portable disk drive, set up a program to record, switched it to Standby, then came back later to find activity going on the disk

It did record the program, recording seems to be OK, so I suppose I've got my $57's worth

Using it is going to be a bit of a learning curve, interface a bit fussy

FWIW, the user manual in a couple of places mentions GH5944 which apparently was something offered by Dick Smith in pre-Kogan days

Oh, and its channel indicator on the front is a really bright, intrusive yellow LED display
