We have a faulty TF5810PVRT which won't recognize the hard disk. When it's powered up the HDD doesn't spin up, it just quietly clicks (a few times per second). The PVR itself works fine otherwise but obviously cannot see the hard disk.
Here's what we tried thus-far:
1) Factory reset - same issue
2) Rolled back the firmware to initial release - same issue
3) Installed the newest recommended firmware - same issue
4) Replaced HDD with working HDD from 5800 - same issue
5) Connected the HDD with just the power connector - same issue
6) Put the HDD from the 5810 into the 5800 - Disk works perfectly
7) Checked the voltages at the HDD connector whilst PVR was operating (steady 12v & 5v) respectively.
8) tested the voltages on the PSU while running (17v, 3.3v, 5v, 8v, 17v, 30v & 12v 5v) - all voltages were pretty much spot on & steady.
We are now looking at this u51 chip/diode as a possible culprit although it looks ok (no physical defects). Plus the voltages getting to the disk were correct & rock steady, so we're not sure.
Does anyone have any suspicions as to what it could be? |

| Another long shot, but I had problems like this when using an HDMI lead. If you're using one, try switching on with the tv switched off, or try a scart lead. |

If U51 had failed, you would not be getting the 5V/12V at the HDD. |
