I have a Technics PR-305 Digital Piano. I had a couple of guys come out to see if they could fix it. Only the LCD display and the front light worked. It must be the power supply.

I have a Technics PR-305 Digital Piano with very dim screen on it. I had it repaired when My digital piano blew and made a humming noise, but now it works I learned that they had parts for it.


You most likely just need a new backlight rather than the whole display. Most any competent repair guy can do the replacement or you can do it yourself if you're a good solderer. Get the backlight here-

I have a Technics PR-305 Digital Piano LCD Display back light That has gone dim can that be fixed to make it brighter?


Hi!
Most cases you can replace just the backlight itself, not the whole display. Contact http://www.telesisgear.com/index.html for the part. It's a relatively simple repair, but if you can't do it yourself, most any music repair shop or music tech can take care of it short order.

Can an inverter that powers the back light of an LCD display of a Technics PR-305 be repaired to make it light up brighter?


Yes. It is a fluorescent tube. It has to be from the OEM though.. It usually comes as a diver board and tube assy.

I have a Technics PR-305 Digital piano The back light is barely light when I turn on the piano Can that be replaced?


yes maybe you may fined that some of the power to the led is being blocked by causing a larger resistant to the led which will cause it not to light up as bright.
