Topfield Trf 7160 Firmware Upgrade4/14/2021
I did notice however that the power dipped back to 4.3v. Unplugged it from the HDD and it was back at 5v.Background: A Mate of fine told me his STB with HDD had died - couldnt record anymore - disk full message.I switch the unit on and heard the tell-tale clicking sounds so replaced the 500GB sata disk.
Put the new one in and the device has a HDD not found message. Tried ex Fat - nothing although it did eventually see it but show that the HDD was full even though it was empty. I decided to measure the voltage out of the PSU as I had read the caps were pretty low quality. I started measuring the caps and the first 2 were greater than 10 tolerance so I decided to replace all 18. Prior to replacing I had measured the voltage on the output connector and it was meeting the stated voltages but the voltages on the output of the Molex had the 5v down to 4.3 and the 12v right on the money. I eventually rigged up my own cable (noting that the cable assignments on a Topfield are different to the norm - otherwise you fry your HDD). However- Im still not having any luck getting the HDD to work. Curiously - the unit struggles to detect a USB at the front and even though it is FAT formatted, I keep getting a message that only FAT USBs are supported. Any ideas (apart from throwing out as I hate sending stuff to landfill) My only thought was to apply some hot air to see if that helps reseat components. BS. In the past, some STBDVRs required the use of a particular brand and model hard drive and therefore did not recognise a foreign unit (or one of different capacity), i.e. HDD must be of the same brand, model etc. Also, many units have utilised a proprietary formatting procedure and also use a proprietary (in-house) recording format. I do not know if this applies to the unit in question, but its worth considering. Edit: Additionally, FAT is not FAT, i.e. FAT formats, so its quite conceivable that an HDD formatted on a computer (if that is what you have attempted) will not be read in a PVR. For more information regarding FAT see e.g.. An owners manual for the Topfield TRF-7150 can be downloaded from. The forums and info from topfield dont state the need to pre-format an internal HDD and I suspect the reason I cant see it is the same reason as to why I cant see the front USB - I suspect there is an issue somewhere around where the data cable connects from the board to the HDD. As this is a differnet model, I cant find the corresponding component. I think the issue is with the Sata cable (and not power as there is 5V going to the unit). Topfield Trf 7160 Firmware Serial Number OfBut, as part of the process I had to reload the firmware - from memory it was to re-initalize the serial number of the HDD in the firmware. It was ages ago, and I think I had to do a forced firmware upgrade (i.e. Will rewire the power cable this weekend and see if that does the trick. I did notice however that the power dipped back to 4.3v. Unplugged it from the HDD and it was back at 5v.
