RIGOL DS2000A and DS1000 rotary encoder replacement - RIGOL company policy

[Kiriakos GR]

When we buy a new scope (and this is our first one), we do not have experiences of oscilloscope servicing and replacement parts.

They are two reasons, which someone will start looking for rotary encoder replacement.
1) An accident and a crash.
2) When the scope this passing it second decade of life, at the hands of an expert user.

Today I have become aware of RIGOL company policy, due a YouTube video.
This customer reported, that  RIGOL this is willing to sale a new PCB with all encoders onboard for 60$ USD. 
And this is the solution for DS1000 series.

The other path, this is of you, shopping alone for replacements.
In this path, you will have to engage with the large and known sellers (chains) of electronic parts.
Possibly you will aim for ALPS (Japan) parts..
Now if you think ordering entire number of rotary encoders = Fail safe thinking = For as NEW working oscilloscope, then the cost of parts and shipping this will not be that economical.

Additionally the responsibility, for performing a proper repair with maximum caution this falls on you. 
   
Here is my personal advice,   if your age this is bellow 28 Years old, you better accept the offering of RIGOL.
When this is available due your local authorized distributor.

An rotary encoder this is a very sensitive component, this it should operates with high precision, and also this has a specific service life.
In conclusion, be very careful with your choices.

They are traces within YouTube, Low-end Siglent, Hantek and UNI-T, these having rotary encoder failures, within the first three years.
The problem begins by the use of low-quality Chinese components, at equipment this aiming exports.

By the numbers, low cost scopes they are in greater numbers out there.
At inexperienced hands, they will fail sooner.

An three years factory warranty, this translates that the components in use, they are of above the average quality, but not immortal.   

Its totally unknown to me, company policy of Keysight, R&S , Tektronix and of GW Instek, in similar situations.
