Can anyone tell me how Humax actually perform a software update?
I was not aware that this could be done over a standard TV aerial, and It's not as if the box is connected to a phone line.

Software updates can be done via the aerial but one thing is for certain Sophie, Humax are not pushing a software update for the machines affected. In any case a software update does not reset user settings as far as I can remember but obviously a Default Setting does and is recommended after software update. I have no idea what is causing this problem but my two friend's with 9300s are not affected.

I also strongly suspect this is NOT a hardware problem
but a BUG that is in the SOFTWARE!

My guess is that it is hardware because boxes work fine for long periods of time and then suddenly develop this problem. That smells like hardware to me. Also the 9200 which uses very similar software doesn't suffer from this problem; again a difference in the hardware could be significant. Why do you think it is software?

I suspect a lot of people have focused on the loss of recording schedule as being at the heart of the problem here, but I believe that this is only one symptom of different issue. That is that the machine spontaneously resets itself to default settings.

My 9300t decided recently that it would reset itself to all default settings every time I switched it into standby (or possibly every time I switched it back out of standby). This meant loss of recording schedule and all other 'Preference' settings such as aspect ratio and instant replay time etc. The oft-repeated Humax stock response of a manual retune didn't fix it (I didn't expect it to - it addresses the wrong problem). I decided then, after looking at a lot of forums, that since a lot of people were having the same issue when they switch the box to standby, perhaps the problem was with the power supply.

I took a chance and changed the capacitors in the power supply. And BINGO - it didn't fix it!

So now I'm stuck with the only (not satisfactory) solution that anyone has found - leave the stupid thing permanently on.

Hi Kermit.
Mine has been permanently switched on since the middle of August!
Previously it had been suffering with all the symptoms as you describe them
that your box has been suffering with.
Up to now this is the only (I agree not that satisfactory) answer!

Cheers!
Steve.

P.S. I still firmly believe that the fact that so many "boxes" of
differing models are failing with the same symptoms is suspicious.

It was evident from the first few pages of this thread that the affected machines are doing a 'sort of' default setting but are not performing a retune as is normal in a 'proper' Default Setting. Power supply capacitor problems had also been ruled out from photos twofords had sent to me, however thanks for confirming that replacing the capacitors does not cure the issue.

Biggles, if only it were possible to diagnose faulty capacitors from a photograph, a lot of diagnostic heartache would be avoided. Unfortunately electrolytics don't always display their failure visually, and without sophisticated test equipment or component substitution you can't be sure whether they've failed or not.

I rather think that Biggles has access to sophisticated test equipment and the skills to do component substitution.

This is my first post here so I hope somebody can advise.

My PVR9300T is 5 years old, and the system info says:
HW rev 1.0
SW 1.00.26
loader a 4.38
update date 7 July 2011.

A couple of weeks ago it began to revert to factory settings for volume, screen resolution, loses recording schedule etc. in the same way as reported earlier in this thread.

I have done a reset and manual retune, but the problem is still there (and resulted in me missing one of the Rugby World Cup matches last week!)

Am I correct to deduce that there is no easy way to fix this problem? Is there a later SW version help? (Where are updates for this model?)

TIA

Hello David,

I can only speak for the 9150T issue that I began to experience but know nothing of the 9300T issue, although, I expect it has the same fault of which there appears to be no known resolution.

Isn't it just strange that these two models have had the same issue after 5 years of life use!!

Regards
Mike

Well, I did eventually have a reply from Humax, but this is what they have said.

Hi Sophie,

You've done all of the trouble shooting steps we can provide I'm afraid, if none of these steps have resolved your issue I'm afraid the unit is faulty and will need to be replaced. Unfortunately we no longer carry out repairs for this model.

Best Regards,
