can this capacitor fix signal fluctuation problem on some of DVBS2 frequencies?
I have original DM800HD PVR with tuner alps BSBE2-401A rev:k.

Should i change the above Capacitor ?

If your tuner is REV: J, K
try fixing Capacitor 680uF 10V as shown in the attached image.
540uF 10v also works.

You mean, We should add this capacitor or we should change it with another one ?

But, my one has 1000uF, 16V , more capable than 680uF, 10V ?

It looks like something has changed in your existing tuner.
So let us go through few steps.
- Just add the capacitor to your existing tuner (as it is with your old capacitor connected) and see if this solves the problem - shown in my previous message.
- If this does not solve the problem, just cut one of the wires connecting the old capacitor and see if this solves the problem
- If this does not solve the problem, you need to get a new tuner.
This could be an M tuner or a BCM4505 Tuner.
The M Tuners are reported to be more sensitive.

Hi BM300,

I have DM800se with BCM405 tuner.

Signal level, the lower the threshold level of distress from the channels. publication is often to go. especially with HD channels ...

I can watch the same channel seamlessly with skybox f3. And more TechnoTrend S2-3200

BCM4505 tuner to receive a better signal of what can be done?

Regards.

I have 2 units with BCM405 tuners one is fine, the 2nd drops out signals for weak transponders.
I solved it using a larger dish and a more sensitive Inverto black LNB.
You can try either solution or both.
Some tuners seem to have a higher thresh-hold and need more signals.
Sometimes a minor dish re-alignment solves the problem.​

How to remove/replace the exist capacitor with the mentioned one ?

You simply cut the wires from the middle (so that you can reconnect the new one in it's place if you want to).
Or you can connect the new capacitor as shown previously using a low heat solder​
