[musicalmemoriesuk]

Ive recently got a used tyros 4 and its developed a fault some of the buttons have stopped working including on the front panel G And Exit on the left side auto fill in intro 3 variation 1 entertainent and swing style select the fault is intermitant and rights itself sometimes. Ive re installed the firmware and stripped the tyros. Checked and re seated the cables.

Sounds more like a hardware problems rather than software issues.
Maybe a loose cable or two, and/or bad solderings?
Take a look inside the T4 to see if here is some tips & hints to help you out:

... or if there is a dealer / repaircenter near by to ask for help?
Good luck, T4 is a great keyboard as long as it work as it should.

For what it's worth, I wouldn't start looking inside the Tyros, unless you know exactly what you are doing. I would contact the person/company/shop, whoever sold it to you.

I suspect it's a hardware problem as well, and unfortunately, most of those buttons come in strips - not just single buttons. They can be repaired, but only by a very skilled technician.

Can't be certain but intermittent start and stop on the same items each time, leads me to think this may be dry solder joints. Just a thought.
