Digital piano repair

[cheap_piano_a]

Hi!
I have some questions regarding digital piano repairs.

1. Is it possible to do repairs yourself?
2. What are the most conmon repairs/problems? Which part gives more problem and requires frequent repair?
3. Usually after how much time the keys on digital pianos start becoming problematic like sticky keys etc?
4. Do digital ones require more repair than their acoustic counterparts?
Thanks

2.  The only thing I've needed to do that wasn't either (i) my fault (ii) a known factory defect is replace
the small battery inside that helps store your settings.

That's very easy on the two keyboards I've done it on (although I've heard that certain models/makes can be difficult to get to the battery, which would be disappointing).  I've had one keyboard that never needed a new battery in like twenty years of nearly daily use.  Not sure why not.

The other repair was a defective Yamaha action that was replaced for free.  Actually, I had the action sent to a local repair shop, and just traded him the old one for the new one and put it in myself.  The tech would have done it for free (well, Yamaha would have compensated him, I'm sure, and they probably did anyway), but I didn't want to wait as it was during the beginning of a heavy snowstorm.

The other action problem was spilling a full pint glass full of wine into the action.  So I took it out and actually washed it in the bathtub (carefully).  It actually worked after that!  I have no idea why the MIDI contacts didn't get corrupted or corroded, so, just got lucky on that one.

I guess the audio outputs could become loose, but I've never had that problem.  That could be a DIY fix, maybe, as opposed to, for example, the power connector becoming loose, which I think is similar to a notebook computer:  soldered onto the "motherboard," and basically not fixable with my low abilities at soldering tiny things.  Maybe, maybe not:  IME they generally build stage equipment with the idea that they will be dropped, plugged in and out many many times, and have some amount of strain put on the audio outs, although you should probably take some care to avoid stressing the outward-facing receptacles and such.

(3) I've heard people complain about keys degrading over time, but I haven't had that as an issue, except for the cases mentioned above.  And my main keyboards have seen pretty good abuse, both in transport to jobs, and nowadays just dwelling in my smoke-filled apartment.

(4) Far less.  No tuning, no regulation of actions, no voicing of felts.  But if you do have an electrical problem inside, I wouldn't even want to imagine what a tech would charge to find and fix it.  They'd probably order a whole new circuit board from the manufacturer and just replace it that way, which I guess you could do yourself.  I'm fairly 100% sure that any of the big name manufacturers will sell you whatever part you need, provided it's a recent instrument.
