DM8000HD Tuner B Dead (Johnny ?)

I installed a second signal cable from the dish and I plugged the cable with the Dream on, I saw the spark that and now does not come out no signal .
Maybe you can fix , if the two tuners are managed by the same chip , and maybe the problem is perhaps only protection ( resistance) come in, which can be replaced.
What do you think about it?
Thank you and greetings.

I do not really know what you want.
Will you try to fix it yourself, or do you want me to look at it.

In any case, it is difficult to say what it could be without some measurements.
It may be limited to a diode, coil, or ic which has a reasonable chance to fix it.

But it can also be a fault with the bcm4501, and it is difficult to replace, but so also difficult or impossible to obtain.

Further information about it, you can find here.
