I bought a Grundig GUVCG2800B digital TV 28" widescreen tv from Tesco 2 days ago. Got back home, set it up. It took numerous scans and half an hour later before digital was picked up but nonetheless it was there and ALL channels were recieved albeit around 40% or below on some channels (as long as my signal booster was on)

However, after attaching external peripherals such as dvd recorder and my BUSH ID DV3 freeview set top box (as I bought this tv so I could record one freeview channel while watching another) via the tv scart sockets at the back, I rescanned the tv for channels in some had been missed from the day before or that peripherals affected things.

This was a massive mistake as now the TV will not pick up ANY digital channels at all! (all analogue channels are still present though) Not even when no peripherals are attached to the tv but the aerial with its booster! I know some digital tv's can be quite unsensitive and require a strong transmitter signal but this is rediculous.

I find this very strange considering my BUSH set top box can STILL now pick up all channels perfectly from the same aerial with booster! And I can't see how one day would make a difference in transmitter signal, I live 20 miles or so from the Sudbury transmitter and there are no current problems there, and I'm sure there are very few interferences in our block of flats and our roof aerial is pointing in the right direction because my BUSH set top box still works.

Surely my freeview tuner can't malfunction in 2 days of use!? It's not as if I have been heavy handed with the tv either so I can't see how it could have been damaged so early on.

Please, please, please can somebody help as this is driving me crazy!?

take it back, make them give you a new one!

Looks like I will be calling Tesco electrical repair to see what they say on the subject.

Why are so many Digital tv tuners not as sensitive as set top boxes?? There are 3 other people at work with the same problem on different makes of digital tv's (digital tv tuner tunes in to digital channels some days if you're lucky but set top box is fine)??? :confused: :confused:

Because analog TV has different signal levels. Signal level can be relatively low to non-existant and you can still see some picture. Digital broadcast is either on or off. You either receive it or you don't. When you lose signal, you see blocky squares on the screen or lose picture altogether.

You can't compare the past to the future mate.
