DIY – Digital Piano Key Repair

Kristian — Mon, 31 Dec 2012 23:29:33 +0000

Digital pianos are great, aren’t they? Today, you can get pretty close to the real thing, while not having to worry about tuning every 6 months, sound volume, and maintenance. Or do you? I used to own a Roland FP-1 digital piano and after a few years of use, I found that several of its keys started to malfunction. Keys got stuck, or would refuse to play a note. What was going on here? Because of the so-called “hammer action” technology, these keys use a hammer action lever to simulate real piano keys. However, unlike real piano keys, these levers in my Roland FP-1 piano were made of plastic instead of wood. Over time, the plastic wears out, cracks, and eventually breaks apart.

I opened up my digital piano, found the problem, and fixed these broken keys by replacing the broken hammers with new ones. Here is a video of how I did it.

Fixing Voice Navigation on my Toyota Navigation Unit

Apparently, my 2004 Sienna JBL Amp was not 100% compatible with the Tundra’s E7006. Once again, eBay saved the day. To handle voice navigation, I discovered that I needed a 86280-OW420 JBL amplifier. I bought this amp on eBay, swapped out my old amp with this new one and it works beautifully. So now I have a Tundra Nav unit with a JBL amp from some other Toyota working nicely in my Sienna.

Here are the steps I took to swap these out.

1. I found the location of the amp behind the glove compartment.

2. After I carefully removed the glove compartment, I could see the amp.

3. The amp connectors are oriented towards the bottom. I disconnected the connectors from the amp. It was very tight in there and I needed need to cut some of the tie binders to allow some more flexibility, after which I could remove the amp.

4. After I took out the amp, I laid them side-by-side. They look identical except for their brackets.

5. Once I put the 86280-OW420 in, I had to pull a wire for the voice navigation:

6. Connect Pin 11 and Pin 13 respectively to …

7. Pins 23 and 22 on the 86280-OW420 amp.

I put everything together, and voice navigation works!

Installing my 2004 Toyota Sienna’s Navigation System

I bought my 2004 Toyota Sienna as an almost fully loaded XLE Limited edition. The main thing that was missing was an in-dash navigation system. Since I really value having an in-dash navigation system as opposed to a portable navigation unit (which is more prone to theft), I decided to retrofit a stock Toyota navigation unit into my Toyota Sienna

Typically, you can install an E7001 from a Toyota Solara into a Toyota Sienna. However, I found an E7006 from a Toyota Tundra on eBay, and I was wondering whether it would work as well.

After some research on www.siennaclub.org, I learned that the E7006 is the same unit used on a 2005 Sienna with a JBL digital amplifier.

I went ahead and bought the E7006 taken from a 2005 Tundra on eBay. The part number is 86120-0C160 / DW468100 – 0170. Although the part number of this E7006 is different from an E7006 used in the Solara, I was able to install it and everything worked fine except for the voice navigation.

Here are some pictures:

The rear connectors look identical as the ones on the Solara Nav Unit. I have connected the VSS signal and the brake signal into E5 pin 17 and E8 pin 17 respectively (on the Engine Control Module).
