Many people are afraid of this message on LCD screen (photo 1).

What is this sinister inscription that can appear on LCD screen
of your Dreambox? Everything is simple: dream-multimedia support services
informs us that this is I2C BUS error by which communicates all Dreambox
modules (LCD screen, Scart multiplexor, entrance tuner), but in our
repair practice it was always entrance tuner (photo 2).
The cause of this is breakage of chip STVO299 (photo 3), which is
controlled by I2C.

There are two ways out: you can change the tuner unit or change only
the chip STVO299
We choose less expensive way and change the broken chip. We carefully
solder out of Dreambox the entrance tuner (photo 4), then solder out
the chip (photo 5).

Then we install the new chip (photo 6). Then we place
back in Dreambox the entrance tuner (photo 7).
In conclusion: we are gathering information about the
causes leading to this breakage, and in future we will write about it.
