Hi all,

I have one of the above amplifiers for home threatre use. It was a cheap and
cheerful unit so i didn't worry about the display fault, but its developed
into being more off than on unlike it used to be. The VFD doesn't switch on
unless the unit gets heated up (i.e leave the doors closed on the ent. unit
for a few hours) and then it will be fine. Wouldn't be a problem except
adjusting inputs etc has no OSD and for channel level adjustment its very
difficult to navigate through the menus and tuning in the radio is basically
impossible without the display.

Do VFD's themselves show issues like this or is it likely to be the supply
to the VFD that is causing the problem ?
