i have recently obtained a 6610 of a friend who had no use for it as he
bought a new one...
 he told me it worked but when i  had a look the power button on the board
is missing.. that dont seem to be a problem as i can short the terminals out
for a sec till it turns on. the problem i have is the lack of display, the
screen is blank. the screen and keypad lights up but there is no display.
            if anyone has any suggestions on what could be the problem or
how i could repair it it would be apprricitaed.    Thanks. David.
