Can a PVR, VCR or TV be upgraded by having a new tuner fitted?

Bill.


Remember that almost anything you buy these days, from a car downwards, is
essentially a computer that thinks it is something else. A TV, a PVR, and
a DTTV VCR fall directly into that category.

So essentially the answer is no.


I2C bus was at one time common on tuners - all the D to A stuff was
programmable not programmed IYSWIM.

In the early days; the front panel micro had firmware on an 8 pin EEPROM
that told the tuner who, where and what it was at start up.

EEPROMs didn't completely disappear, but I think they're just user
settings - the firmware is flashed on the MCU.

Years ago I encountered a Ferguson set with corrupted firmware - nothing to
lose, I borrowed an EEPROM from a completely different TV. The ferguson
decided the alien EEPROM was unformatted, so it prepared it and reinstated
the firmware from PROM.

I think there are some PVRs where the tuners can be changed. There being
satellite, terrestrial and cable tuners.

As a part inside, No (it's difficult).

As an added external box, yes for TV, yes for VCR (why?), no for PVR
(not supported[1])

However an external box needs to provide a compatible interface (SCART,
HDMI) and resolution.


[1] - alas, they ain't no real TiVo's anymore ....

Thought was better to have a new tuner than have an additional box.
Why not not for VCR?? Many of us still have tape collections and some
older neighbours are familiar with them and confused by YouView etc.

They're often SMD and pretty much impossible without wrecking the board.
Some are part of the board and can only be dismantled.

There's still a lot of through hole tuners about, desolder the
connection pins - make sure they're all free and you can usually melt
the solder on the tabs and ease the can out bit by bit.

Through plating is a real pig!!!

Sounds too much hassle.

Yup. An external freeview box (from 10 years ago) can be added and it
doesn't need to be much of a box, some are the size of a scart plug.
Then all the user needs to do to record a program, is switch to this
input, change the channel to as necessary, hit record, feed the dog,
wish the wife goodnight then go out to the pub.

If all day drinking (or next day sleeping) is envisaged, then user
mastery of timer controls on *both* the VCR and the freeview box would
be required, and there are then too many things to go wrong.

PVR is the promoted solution, but some have far too much reliance on the
users ability to work the GUI to schedule and find things after they
have been recorded. And compounded by a button heavy remote control, or
multiple functions assigned to too few buttons.

TiVo (in all its guises) was probably the best worked out there. The
YouView scrolling interface needs work - it's not very obvious what day
ye are currently scrolling in!

Independant IT Folks now have hardware platforms (Raspberry-Pi etc..) to
self engineer some way out of this mess. I can certainly imagine a few
tactics, but currently I'm busy saving the world from roijo jg[uhgg [hu[

Reminds me of a friend, who has a friend who left her phone out overnight
and got it wet, then plugged it into a charger and got {fizz}.

She asked me why you couldn't just replace bits in the phone, or add a
fuse to the charging circuit to prevent this kind of thing.

The answer was that these days everything is so tightly integrated that it
is very difficult (if not impossible) to identify individual components,
let alone replace them.

This is leaving aside the tendency of manufacturers to glue the whole
thing down so it can't be serviced anyway.

Back in the day, when electronic devices were big and the boards were
populated with individual components (each with a useful colour code to
aid identification) a brave person with a soldering iron could work
wonders.

In these days of the SoC repair is usually out of the question and the
whole assembly is so cheap anyway that replacement is the usual route.

Cheers

Talking of the inability to repair nowadays a friend bought a Combo VCR
recorder DVD player when TJ Hughes were selling them as end of line. It
soon developed a fault and they could not replace or repair it so just
gave him a refund.
I have a TV that came with a five year extended warranty. What will
happen if it fails?
I once bought a graphics card that failed during it warranty period and
they replaced it. That one later failed when out of production and they
did not want to give me a later model and would only offer a 50% refund
on the purchase price due the the use I already had from it.

Except things aren't very repairable these days. Even when UHF
television came in in the 1960s, you couldn't just replace the tuner.
(Yeah I know there were lots of other differences.)

All right for playback, but recording with a VCR is sub SD.

If you want to keep recordings I expect Freeview DVD recorders are
still available, if the haven't been blocked by the DRM police.

When the one I'm using fills up; I scrounge another on Freegle.

If I have to repair one - I look around for a bigger HDD while its open.

And in many of the Enigma 2 boxes which have plug in tuners albeit
most/all terrestrial tuners available for those boxes are already hybrid
SD/HD and cable.
