Hi!

Since I used the Update function on my VUPlus Duo 2 in early March 2017, it began with sporadic "Tune Failed" errors. Switching to other programs and switching back brought back the picture most of the time.

Then it began to annoy with timer recordings (0 bytes with tune failed).

I then mainly used the DVB-C tuner which after some days began to show block artefacts and very huge BER in "Sat-Finder". I installed every Openpli-Update during March hoping for better times, but no help.

Changing the Vu+Duo2-Sat-Tuner to a new bought one helped for 1-2 days, then the "Tune Failed" came back. Plugging the Cable into any of the two sat-tuners did not help, Connecting the Vu Duo in the room where the VU Solo works helped for some hours, then "Tune Failed" again.

The Vu Solo works on the cables in the VU Duo Room, so the cables and switches seem to be OK.

I read about many problems with the Vuplus Duo, including Capacitors (cannot see any faulty parts or even the same parts an on some pictures on the net), hot tuners (here, too), Diseqc-settings (sometimes works after changing some Pause settings, then again not) or Spaun switches not working with Vu+.

I flashed for testing Original VU+, Blackhole, OpenATV, and VTi, but the same error.

What do You think about it? Strange, that a possible Hardware Problem begins with a Firmware Update.

Thank You for any Help.
