Weak psu?

Got a dm800 that was working fine, now showing no signal, have swapped it over with another and same error, checked the cabling, everything seems ok.

Could a weak psu cause the no signal?

TIA.

More likely a duff tuner or LNB.
 
If you have used the same PSU for both receivers, that is another common factor. As the tuner is the most pwoer hungry component, you may wish to try another PSU.

Did you use the same tuner in both receivers?

If you can try the receiver at another location that will rule out the LNB.
 
Thanks for the replies, but its a cable box, posted in the cable section?
 
Ahh!

Process of elimination is the same though, you must test only one thing at a time though

Suspect PSU
Try another PSU

Suspect signalling issue
Try receiver in another location- Proves receiver is fine
Try anoither device where current receiver is located- if other device fails, signal issue in location

Software/Frequencies
If the frequencies you have in receiver are for wrong area, you won't get signal

You will need to provide more details as to what you have done

Process so far, box was working an day or so, no problems, then no signal.

Swapped over for a different, working box, same netid etc ..

Same issue, checked the cabling, hadn't been touched, tried new cabling, same results.

When the box boots up, the correct time is displayed on the lcd, leading me to believe there was a signal, but on trying without the feed connected, time was still displayed.

Leaves the only two other possibilities as being the psu, same psu used on both, or the feeds been disconnected outside, wich is brutal luck if that's the case. Lol
 
You have isolated the common denominators. Rule them out one by one. Might be an idea taking receiver round to a mates house and you can test both factors one by one.
 
You know what id try.

Just to rules out image corruption providing the sims are the same, backup the image on the working box and flash it to the none working box.

After that make sure the tuner is fully pressed home in its slot. Failing that swap the tuner out of the working box to the none working box if it works then tuners goosed.

Still dont think its a PSU issue or why would the other box work ?
