_____________________________________________________________
Model: DTR-4.6 (for ALL unit service info )
Subject: Input work Digital lit on display, No audio output to speakers.
Symptom: Use DVD RCA audio input, no audio signal at Pin 4,5,6,7 at P3101B.
(Check with Scope should have 2.5 V DC with 0.2 V pp audio
** USE SCOPE TO CHECK **
Missing Output from pin 8 to pin 15 on P3101B digital out Should be
0 V dc with 0.4 V pp) o v
0.4 v pp
Solution: First check microprocessor Q701 control signal output. (5 V. )
5 V R267, R268 VOLSTB and VOLCLK should have 5 V dc with
0 V 5 V pulse down to 0 V when adjust volume control. ( also at P3105B)
R659 VOLDAT should have 0 V dc with 5 V pulse when adj volume.If low
Remove pin 58,59,60 On Q3003 if pulse was low. To check control signal back
Up to 5 V. If control signal still low Q701 may be def.
If yes have 5 V pulse Q3003 was leaking Replace new IC.
Next check +7 V and – 7 V power supply on Q3003 and Q3009.
Remove XM Radio NARF-9688 and VIDEO Board NAVD-8657 .
Check R3127 right side Reg Q3005 out pin 1 should be + 7 V. If low or +2.5 V
Q3003 or Q3009 may be leaking. Remove pin 19 or VCC pin 39 on Q3009 and
Check. Same as Q3006 out pin 3 ,Right side R3128 should be – 7 V. if low
Replace def. Q3003 or Q3009.
If control signal is good CD audio signal go in to Q 3003, +7 v
And – 7 V all good but no ADRT-,ADRT+ , ADLT- and ADLT+ audio out
Replace Q3003 input select IC.

__Switch Problem May find in any DVD ? Receiver too !!_____________________________________________
Model: DV-CP701/CP702 ( Info May use on other DVD )
Subject: Standby is light is ON but set will not power ON (power on Tray move itself)
Symptom: The Standby light is ON but the set will not power ON when the Standby
button is pressed. (some unit power on or play disc T ray will open close itself)
(Check Voltage with Scope int leaking switch May not show on ohm test )
Solution:
Reset circuit to confirm that it is operating normally and crystal OSC (X801) to verify
that it is on frequency and supplying 2.5V to 5V pk to pk. If these items are normal
check the voltages on the DISPLAY board at KEY0, KEY1, KEY2 and KEY3. The
voltage at KEY0 through KEY3 should read 4.9V ~ 5VDC. If any of the KEY voltages
read low check the associated momentary KEY switch to see if it is stuck in a closed
position. If the switches check good, check the DISPLAY board capacitors C827, C828,
and C829, to see if any are shorted or leaky. Replace any defective parts and re-test.
If Switch is leaking replace the Bad switch.

CONFIDENTIALITY NOTICE:
When Power board was good Standby Lit Unit can not turn on power.
Use scope check Display board U3 P804A
When K0,K1 or K2 Voltage much lower than 5 V. Microprocessor lock up
Unit will have no function.
If K0,K1 or K2 line Lower than 5 V. First check all switch not lock in.
Remove U8 and U9 PCB from U3 Display board . If K0,K1 and K3
Voltage low than 5V.(2V to 4V) Replace display board.U3 NADIS-7808.
When you have 5 V after U8,U9 removed check any K0,K1 or K3 line Voltage
lower than 5 V when you connect U9 orU8 (U7) board back to U3. Replace that board.
Or check out Def. Push switch and replace. 25035718 NPS-111-S681 If SW was leaking

READ ALL INFO IT WILL Help Y ou Save Time
Please print out circuit which you work on write down voltage you check. TechEmail
to us all info When you need us to help ! Give us model # and Ser:# Customer
info and problem. ( Always use scope to check)
When THRM line Voltage too low 0.1V or too high over 2.5V.Unit go Thermal protection in 3 sec.
GENERAL CHECK LIST FOR INTERMITTANT operation or NO AUDIO ,VIDEO
1. What is idling current on each channel? Adjust and test. (If Idling adj. not change !
replaces surrounding transistors and idling adj. resistor.
2. What was customer setup on speakers level? If too high reset unit and test.
(It will over drive amp. When input signal go high unit will go protection)
3. What is each channel voltage from ID+ to chasses ? Good Unit about 0.04V
If a channel ID+ voltage much higher than other. Replace the two input transistors
(use same transistor) at driver circuit. It will drop this voltage down.
4. Use scope check do you have DC in any audio line ?
( When adj. volume up or down. Press and change input bottom) If yes find def. parts
IC mutting transistors.
5. What is voltage on IPRO ( PROTECT) Use scope ? Check transistors it may leak.
6. What is voltage on THERMAL line ? Check transistors it may leak ( delay act. Some unit
5 sec, some unit act in 5 min. some 10 min or more. To turn unit to Thermal protection)
Unit use TXSR XXX LM61CIZ Thermal Sensor. THRM line about 0.95V if unit turn on
and 1.5V. Unit will go Thrmal protiction in
7. Check power supply to all DSP IC . Use scope check voltage and noise!
a. If unit audio work intermittent .Warm up lost audio. Check +5V,+3.3V and +2.5V if
Low down and noise! Check Rag IC . Some unit is in amp board. Not in DSP board.
Add more thermal joint compound and test.
8. When you have audio signal go in to a IC but no output.
a. check you have good power DC supply to this IC ?
b. do you have good control data from microprocessor to the IC ?
15 min. replace this sensor !!
microprocessor. ( If microprocessor not available than replace PCB. some unit in
