A "refurbished used piano " brings back bad memories
for me.I bought such a piano from a rather unknown small dealer
who sold only these used" refurbished " pianos.
I'have told this story before I know. The piano was a disaster.
Our technician wrote a full report of the many problems of this
piano and we were able to return it to the dealer.
This was a grey market piano and the problems were revealed
within a few days.The term refurbished is often used with these
pianos and I still do not know what it means.
The piano came from Osaka (sp),it was a Yahama YU10 made in
2012.
Is this technician that suggested the Damp Chaser from the dealer?
By the way I am really sorry you have had this problem with this piano.

If the op bought this piano through a dealer here.There must
be a warranty. Although a G2 does not sound like grey market
model .,Is there a possibility the model number was replaced
or does it not have letters which show the model?
This is a used piano from Japan that has been refurbished. ,
What is this -a paint job?
Some of these pianos are successful some are not.
I think she still may be able to have the piano replaced or she should be refunded.There just seems like too much deception going on.

The Dampp-chaser system is not going to do ANYTHING for a grand pinblock. While I am a proponent of the system, from what you have described what you really need is room humidification in the winter. The system works very well for upright pianos. Somewhat limited in a grand.

Though ultimately, if the tuning pins are in fact that loose, what you really need is a new pinblock as well as new strings and dampers. That's going to cost significant money to do it CORRECTLY.

You likely have a grey market piano in a very dry environment. Loose tuning pins can happen in that situation. The inexpensive fix for loose tuning pins is to treat the block with C/A, which your tech should have offered to do.

Installing a humidity control system in a grand piano does not reach the pin block like it does for an upright piano. You need to add moisture to the room, via a humidifier, preferably a furnace humidifier.

The other type of repair is to re string the piano with oversize tuning pins.

Natol,
If you did buy the piano in the US and have a warranty. You could
get in touch with the dealer about this pin block problem.
I do not know how old your piano is. You could get a written report
from an independent technician and present this to the dealer
where you bought your piano.Sometimes people have to fight for
their warranty.That's OK you can do that.
This problem is not typical for Yamaha pianos unless perhaps for
some grey market pianos.
Please let us know what happens about your piano.
