5. TROUBLESHOOTING
1. Test Mode is not activated
With the set assembled in the front panel, the Test mode does not
become active if any button was pressed by any reason.Under this
condition, the power is not turned on even in the normal status.
(The set is kept in Standby status = Red LED is kept on) Not only
the buttons are inactive, but also a signal from Remocon is not
accepted. To check this condition, with the self check port (pin
yl
of IF CON) kept in “Low” status, supply the AC power, so that the
Test mode is forcibly activated. On the board, short the lands where
SELF is printed. The IF CON checks the self check port only after
the power on reset (only when AC is supplied; not in Standby sta-
tus). If any button was pressed, the button name should be dis-
played on the FL display tube. Though no button is pressed this
time, display of other than NOTHING implies that the button was
pressed. However, the set will go in Standby status immediately
unless the FFC (pin
qj
) connected to the MB-85 board is discon-
nected in advance.
2. Power is not turned on
1
Red (STANDBY) LED does not light up when AC was sup-
plied. The power (EVER 5 V) is not supplied.
X201 is oscillating.
Loose connection of the connector between FL board and FR
board.

pressed. Any button is kept pressed.
PCHECK (IF CON pin
uj
) is over 0.1 V.
3
Green LED lights up when POWER button was pressed, but
red LED lights up again after several seconds. PCHECK (IF
CON pin
uj
) is abnormal. (Slow rise time from 0.1 V to 1.5 V.
Voltage must be less than 1.5 V)
SYSTEM CONTROL does not operate normally.
