SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.
1. Check theareaofyourrepairfor unsoldered or poorly-soldered
connections.Checkthe entire board surfacefor solder splashes
and bridges.
2. Check the interboard wiring to ensure that no wires are
"pinched" or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
4. Look for parts which, though functioning, show obvious signs
of deterioration. Point them out to the customer and
recommend their replacement.
5. Check the line cord for cracks and abrasion.
Recommend the replacement of any such line cord to the
customer.
6. Check the B+ voltage to see it is at the values specified.
7. Check the antenna terminals, metal trim, "metallized" knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGETEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5mA (500 microampers).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
TW-540A. Follow the manufacturers' instructions to use these
instruments.
2. A battery-operatedAC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The "limit" indication
is 0.75V, so analog meters must have an accurate low voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
of a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2VAC range are suitable. (See

2. HOWTO ENTERTHETEST MODE
While pressing the [RETURN] and [STOP] or the [TIME/TEXT] and [EDIT] buttons of the DVP-CX850D at the same time in the standby
mode, press the [SET UP] button of the remote commander to enter the test mode.
When the DVP-CX850D enters the test mode, the automatic display sequence of the FL display tubes starts as follows.
1. All segments of the LED and the FL display tube turn on for about five seconds.
Note: The [DIRECT SEARCH] LED and the [DISC CHANGE] LED turn on alternatingly while all FL display tubes turn on.
2. Prototype model name is displayed.
As to the display indication of the FL display tubes, refer to “9. FLD AUTO TEST OPERATION”.
3. Date of the last update of the program is displayed.
Example: 990604
4. The message [GRID TEST] appears. Then the odd number grids and the even number grids flash alternately. (Three times)
5. The message [ANODE TEST] appears. Then the odd number anodes and the even number anodes flash alternately. (Three times)
6. Returns to step 1 “All segments of the LED and the FL display tube turn on for about five seconds.”
Steps 1 through 6 are repeated.
3. HOWTO EXITTHETEST MODE
Press the [POWER] button of the DVP-CX850D and the remote commander. The FL display tube turns off and the red POWER-LED only
turns on to return to the standby mode as long the serial communication between the system controller and the IF controller works correctly.
While pressing the [STOP] button, press the [POWER] button to return forcibly to the standby mode.

1.TESTINGTHE BUTTON FUNCTION
Press any function button (except [POWER] of the DVP-CX850D in the test mode. Then the machine exits the FL display tube automatic
display test mode. As long the button is kept pressed, the FL display tube shows the function name of the pressed button. When hand is
removed from the button, the message [NOTHING] appears. For the function name of the buttons on the FL display tube, refer to the
following table.
When any of the self-illuminating buttons (the buttons equipped with LED), every pressing of the button toggles between turning on and off.
To test the MULTI CHANNEL LED (blue LED), press the [RETURN] button because the LED does not have its corresponding button.
The direction pointing buttons function to enter the special modes as shown below.
R: FL display tube grid check
r: LED check
T:Direct search dial check
t:FL display tube anode check
All buttons are judged by the input voltage value to theA/D port. The reference voltage of theA/D port is EVER 5V. The input voltage value
is calculated with 10-bit accuracy. Only when the input voltage value agrees twice, the value is input to the A/D port in order to remove
chattering of buttons.
When the buttons of the IF controller are judged, theA/D port had a dead zone so that the message [IGNORE] appears when an input voltage
in the range of the dead zone is input.
2.TESTINGTHE REMOTE COMMANDER SIGNAL RECEPTION FUNCTION
When the machine receives the remote commander signal while [NOTHING] is displayed, the function name of the remote commander code
is displayed on the FL display tube. The machine receives the DVD category code only.
The [DISPLAY] button of the remote commander functions to switch the display between the function name display and the code display.
When the code is displayed, the message [REM NO xx] appears. The characters xx indicates the received code in the hexadecimal number.
When the remote commander signal is not received, the message [FF] appears.
3.TESTINGTHE SYSTEM CONTROLLER ↔IF CONTROLLER
SERIAL COMMUNICATION FUNCTION
The bi-directional serial communication between the system controller and the IF controller is performed normally at the rate of 24 ms. This
mode can easily check if the communication is correctly performed or not.
When the non-relief type characters such as [VIDEO CD], [DVD] and [CD] in the left of the FL display tube turn off while [NOTHING] is
displayed, it indicates that the serial communication with the system controller is correctly performed.
When these non-relief type characters turn on, it indicates that the serial communication with the system controller is not performed.
However, during the period of several seconds (until initialization of the MB board is complete) after the test mode is activated, the non-relief
type characters can turn on. This is normal.
4.TESTINGTHE CLICK SHUTTLE FUNCTION
This test checks that the IF controller can recognize the rotation of the click shuttle control. When the illuminating segment moves as the
click shuttle is rotated during the subsequent grid check and the anode check, the click shuttle is normal.
5.TESTINGTHE FL DISPLAYTUBE ILLUMINATION CHECK
The FL display tube can be simply checked by the automatic display mode, but can be checked more precisely by this mode.
All segments of the FL display tube are turned on when the [STOP] and [PLAY] buttons of the DVP-CX850D are pressed at the same time.

5-2. Grid Check (Pressing the Rbutton enters the grid check mode)
Any desired grid of the FL display tube can be turned on one after another by this mode. (All anodes of the corresponding grid are turned on.)
Move the click shuttle control of the DVP-CX850D to select the desired grid to test.
When the click shuttle is rotated in the clockwise direction starting from G16, the grid G15, G14, —— G1 are turned on. After G1, the grid
G16 turns on. Any one of the grids turns on during this test.
5-3. Anode Check (Pressing the tbutton enters the anode check mode)
Any desired anode of the FL display tube can be turned on one after another by this mode. (All grids of the corresponding anode are turned
on.)
When the click shuttle is rotated in the clockwise direction starting from P1, the anode moves to P2, P3, —— and returns to P1 after the last
anode. Any one of the anodes turns on during this test.
6.TESTINGTHE LED CONTROL FUNCTION
The LEDs can be turned on one after another when the button ris pressed.
When the click shuttle is rotated, the LED to turn on moves.
The self-illuminating buttons can be turned on and off, not using this mode, but by operating the buttons.
7.TESTINGTHE KEY BOARD CONTROL FUNCTION
When [ENTER] of the direction pointing button inside the click shuttle is pressed, the message [Key Board TST] appears in the state waiting
for keyboard input.
The numerical and alphabetical character inputs are accepted. The typed characters appear on the display.
When pressing the [Caps Lock] button or [Num Lock] button turns on the LED, the keyboard circuit is judged to be functioning correctly.
The keyboard of the IBM compatible PC of the USA model can be connected.
8.TROUBLESHOOTING
8-1. Cannot Enter theTest Mode
When any button is pressed by some reason after the front panel is already attached, the machine cannot enter the test mode.
The main power cannot also be turned in this state. (The machine stays in the standby state. = The red LED is kept turned on.)
The remote commander cannot also control the machine, not only the button operation is invalid.
To diagnose this state, turn on the mainAC power while the self-check port (pin-69 of the IF commander) is kept "Low". The machine enters
forcibly the test mode. Alternately, short the soldering lands that have the indication SELF on the printed board. The IF controller checks the
self-check port only after the power-on reset. (It does not check the port in the standby mode.)
Pressing any button displays the button name on the FL display tube.
If any display other than NOTHING appears even though any button is not pressed, the machine mis-operates as if any button is pressed. In
thisstate,besure to removethe FFCfrom pin-15 that is connectedtothe MB board, otherwise themachineenters the standby stateimmediately.
8-2. The Main Power Cannot BeTurned On
1.The red (STANDBY) LED does not turn on even though the main AC power is turned on.
The power (EVER 5V) is not supplied.
X201 does not oscillate.
Connectors connecting the FL board with the FR board have the defective connection.
2.The red (STANDBY) LED remains ON even though the POWER button is pressed.
Any button is in the state of being kept pressed.
PCHECK (pin-77 of the IF controller) is 0.1 V or more.
3.The LED turn on in green when the POWER button is pressed, but returns to red several seconds later.
PCHECK (pin-77 of the IF controller) voltage is not normal.
(Rising up from 0. 1 V to 1.5 V or higher is slow. Or the voltage does not go higher than 1.5 V.)
The system controller does not operate correctly.
