Hello ,
suddenly the dec began an unusual behavior
first with digital terrestrial channels and then with satellite.
after about half an hour the image starts to block then starts again and so on. I thought they were channels that are not well received but it is not so because attacking the other my dec and verifying the signals with the antennist are all good.
I do not understand if it's a power problem

Most probably the capacitors from the PSU are becoming old and doesn't give enough anymore...

Look here, it's good to replace these capacitors by high quality Rubyconn 105° ones.

You can find them with the ID printed on the PCB of the PSU,

Change the small electrolytic caps under HS1 (heat sink1) and C6 just above.

C36 = 100 microF 25V - 105°
C31 = 10microF 50V - 105°
C38 = 1microF 50V - 105°
C23 = 47microF 25 - 105°
C6 = 1 microF 50V - 105°

It's the same PSU as for DM8000HD, please check with johnny from jb8a8f8.com, and your box is then most probably a DM7025+,

check from jb8a8f8.com but if so, can not the capacitor change be applied?

I think it's a different design, the DM7025 had a different PSU than then DM7025+ (that is a DM8000HD PSU)

We have a solution here, for DM8000HD PSU, but generally the original PSU seems to work better than the clones one that are discussed on this topic, I let you read it but best is really to open a topic about this issue, talking about the possible PSU problem to Johnny at http://jb8a8f8.com.
