Why do all my diseq switches die?

Re: Why do all my diseq switches die?

Along with static electricity, also shortcuts must be considered too.Sometimes, F connectors are not sealed well and it makes shortcuts for the STBs through the dish line, reaching the diseqc switches.

When it is dangerous for switches, then its also damage the STB ?

If you don't wanna have this problem you just need to link your dish pole to ground.

Re: Why do all my diseq switches die?

Yesterday, one of my diseqc switches died unexpectedly.It was raining out and after sometime I realised that, it was exposed to pure rain for some time.This is also a precaution to consider in this kind of failures.

Check the ground connection of your box.

Try this test:

Unplug the coax dish cable from the box, keep the connector in one hand and with the other hand touch the connector on the box....

If we won't get a reply in 3 days means....

Seriously use a tester and check from the cable (disconnected) to the box do you have tension/current ? in this case is you ground connection which is not good at home.

For begginers without any measurement device, if you touch with one hand the receiver and with the other the cable and you electrocute a little, then you have a grounding problem :P

Re: Why do all my diseq switches die?

Funny enough, according to various forums, many people have had the diseqc switches die on them and then they work again a few days later. In fact some people have said to have kept swapping dead switches periodically because they work again after a while.

Have a read what these people have said, just ****** search "diseqc switches died" and look at the first 4-5 results, it might help you.

On havy loads, because of temperature and humidity, some components may malfunction, after cooling it can work again.

Being made manly from some IC and capacitors,inductors,transistors, this could be the single plausible explanation for what you are sayng.

Defective weldings can cause such behaviours, too. You could try to use some copper and spot-welding sealer spray that helps weldings work better...

Indeed welding is more plausible, you could also try to a phone repair shop where they have special tools for solving so called "cold contacts".

For this problem on cellphones they use a special hot air blower that will weld back problematic contacts

Re: Why do all my diseq switches die?

you can fasten behind dish in shadow and also its better the switch have about 10 cm far from ground

Re: Why do all my diseq switches die?

10 cm far from ground

Why do you have to be on 10 cm from ground, you worry about humidity or is somthing else ?

yes this is my experience humidity and freeze water while rainy

I thought that it has somthing with grounding influence, ok it just about weather

Re: Why do all my diseq switches die?

Never happened to me but you have a point here, even if you simple deselect the DiseqC by mastake, it won't work anymore.

My guess is that you don't have rain bouncing higher than that in normal conditions.


But back to my main reason for posting. "Grounding or Earthing of Equipment"

This, if done incorrectly is more dangerous than doing nothing.

Normall satellite boxes are double insulated. That means the mains power is isolated from the exposed conductive parts via the transformer/PSUexposed and components. ie the metal case and connections.

If you ground your dish incorrectly, you could be providing a electrical path to ground for any accidently exposed live conductors.

I don't have all the answers myself, although a bit of time on goo6le would be wise.


PS A DVB card in a PC differs from a STB in that it is within an earthed case

Re: Why do all my diseq switches die?

the really hard job is to get the real defective device:
my problem(dm800 clone, diseqc switch 8/1,):
sometime, not always, after I watch some tv-station from LNB1,
i get no signal on the other LNBs (on tv stations with usally 80% strong signal)
but if I go to the setup-tuner and change anything(nothing important, current level from 600mA to 360mA or the other way etc.) and save, i get back the signal to 80%

I cannot estabilish if my dm800 tuner is defective or if it is the switch or some problem on LNB1.
(I cannot test becase i have no spare diseqc switch or reciever and hard acces to my antenna)
