7.1.5 TROUBLE SHOOTING

XV-DV55 microcomputer troubleshooting

Symptom of problem

• The power supply does not enter .

• The standby LED lights even if the

POWER key is pushed.

• It enters the state of POWER OFF

soon even in case of the POWER

ON.

• DVD does not operate at all.

• Time is not displayed in FL DISPLAY

at the DVD function.

• The operation key is not accepted at

all.

Check method

• Whether terminal RESET (12Pin) is "H" is confirmed.

The operation of the RESET circuit is confirmed if

not becoming "H".

• Whether the AC pulse is input to AC input terminal

(11Pin) is confirmed. If the AC pulse is not input,

the AC pulse generation circuit is confirmed.

• The microcomputer or the oscillation circuit is broken.

The microcomputer or the oscillation circuit is

exchanged.

• If the voltage of the 3.3DETECT (13Pin) terminal of

the microcomputer is 2.9V or less, the voltage is

adjusted to 2.9V or more.

• Whether terminal (27Pin, 78Pin, 98-100Pin) for the

communication with the DVD microcomputer does

the communication operation is confirmed. If the

communication operation is not done, whether the

B to B connector etc. are disconnected is confirmed.

• Whether "H" is output to terminal DVDRESET

(87Pin) is confirmed.

• When KEY is not pushed, whether KEY input

terminal (18Pin) is 5V is confirmed. If the KEY input

terminal is not 5V, whether KEY SW on the line

breaks is confirmed.

Thought cause

• The microcomputer is not reset.

• The AC pulse is not input.

• The oscillation circuit of the microcomputer

does not oscillate.

• If the function is DVD, the 3.3DETECT input

is 2.9V or less.

• It does not communicate with the DVD

microcomputer.

• It is recognized that other KEY has already

been pushed.
