Kyocera  replaced over [70] J-51's here in this area [ SW Colorado ] with
low output, browning on the front and bubbles on the back stating that it
was a manufacturing problem and this was 7-8 years down the road from date
of installation. My hat is off to them for their warranty.

Dave,
I've had a small number of those J48s go hooey as well.
Most of mine had a circular browning on the face of the module caused
by the J-box. I assume that is where the string contacts failed.
They make a nice coffee table or wall art, but aside from that....
Good Luck, bob-O
