do you have any idea about the slurred speech on one of my boxes, please?
Sound has now gone on tvonics box, replaced scarts etc, def the box. That did not last long.

Nick: If you are referring to slurred speech in the same way as say a slowed down gramophone record, then to be perfectly honest about it its something that I have never at any time experienced with digital equipment, stuttering speech yes! but not anything that could be described as an analogue type slur.

If you have completely reset the box then that's about the only thing that you can do, however I believe that software updates were available for some models although I am not able to check on this as I am unaware of the model you are referring to, although as the company went into administration the link I am thinking about may no longer exist.

Anyway, if you come back with the model number of the PVR in question I will have a check.

By the way, the undermentioned link is for a company that any enquiries concerning TVOnics devices should be addressed to, clicking on "contact us" seen on the left hand side of the page.

JB, the tvonics pvr, which has lost its sound, is DTR2250
The box with the slurred speech, which appears slow and deeper voice yet pic is in sync, is Digital Vision AD BEAV
Which of these two companies is in administration?
Many thanks

Nick: Thanks for the clarification on that, and in answer to your question its TVonics.

Will check up on both devices mentioned.

Nick: Should you be referring to me then I am still around, but though with this being totally dependant on work commitments and which may at times involve me working over night at short notice should I be required to assist some other engineer, as indeed has recently applied.

Understood, JB. Just wondered if you had managed to find info on the two devices.
Kind regards.

This is boring. No Engineering works, no re-tunes required and all muxes received loud and clear. What is a man to do?

Nick ; Apologies for delay in replying, but with regards to the answer to your question, although I did make enquiries / checks on the database during my usual Friday stint at the service depot it didn't actually reveal anything more than I already knew, insomuch that the only action you can take that might hopefully rectify the problem complained of is by carrying out a software update on the box, but though with major stumbling block to carrying this action out being the fact of every web link associated with TVonics software updates being inoperable.

This somewhat leaving the situation in limbo, as the only chance that anyone would have of being able to update their box is if some TVonics enthusiast (as they do exist!) had made personal copies of the completed downloads prior to the companies link having been broken, however no amount of searching by me has as yet been able to find anyone that could maybe oblige, and so the situation does not look very promising.

Apart from that though, maybe you could inform me as to the software version fitted in your particular model, as this would enable me to cross check it against others in the series thereby giving me an idea of the level your box is sitting at, the software version installed in your box being found by pressing: Menu / Service / Manufacturers details.

As far as the other box (AD-BEAV) referred to is concerned, unfortunately its really a case of grinning and bearing it as no info was seen mentioned about this model, therefore with it being assumed that no fixes are available for this device, the link below when opened giving an example of the prices that these boxes were being sold off at, or at least attempted to as the only offer I seen was half of the asking price.
