I changed the value ".demod_address = 0x19" by ".demod_address = 0x10" 
and resolved

Attached list of changes I made.


Results:

Analog TV can be seen, but no sound.
If I use xawtv or VLC the image is in the middle of the screen and there 
are stripes, as if interference. If I use tvtime will look good.

Digital television: not tune any channels with w-scan or gnome-dvb-setup.
But with the latter, it captures 2 weak signals, but I can not know 
which is.
Under windows also capture 2 channel and I'm in a place where the signal 
is low.
I'll try to have more signal strength.

If I run dmesg after scan channels I get the following:

[ 3474.858537] mb86a20s: mb86a20s_set_frontend:

[ 3475.182829] mb86a20s: mb86a20s_read_status: val = 2, status = 0x01

When detected signal with gnome-dvb-setup, sometimes gives this warning:

Message from syslogd@linux at May 4 01:48:38 ...
kernel:[ 3359.202289] do_IRQ: 2.145 No irq handler for vector (irq -1)


Thank you very much,

I improved the antenna signal and I've got this:

As there is little sign, I asked another person to try and got this:

$femon -H
FE: Fujitsu mb86A20s (DVBT)
Problem retrieving frontend information: Operation not supported
status SCVYL | signal 6% | snr 71% | ber -1217255176 | unc -1217744071 |

Problem retrieving frontend information: Operation not supported
status SCVYL | signal 12% | snr 71% | ber -1217255176 | unc -1217744071

and this:

[ 397.962795] mb86a20s: mb86a20s_read_status: val = 9, status = 0x1f
[ 397.962798] mb86a20s: mb86a20s_read_signal_strength:
[ 397.983108] mb86a20s: mb86a20s_read_signal_strength: signal strength = 
4096
[ 398.019975] mb86a20s: mb86a20s_read_status:
[ 398.020461] mb86a20s: mb86a20s_read_status: val = 9, status = 0x1f

I think these values ??would have to watch TV, but no.

Suggestions are welcome

Thanks in advance
