ERR0: Booting Fail(Flash boot code is broken or CPU surrounding circuit badness.)
ERR1: Booting Success(CPU interior function initialization failure, system memory(U8)
access is unstable)
ERR2: CPU interior function initialization success(Became down before NIM initialization)

5. Trouble Shooting
There may be various reasons for the abnormal operation of the receiver. Check the receiver
according to the procedures shown below.
If the receiver does not work properly after checking it, please contact the dealer. Don’s open
the receiver cover. It may cause a dangerous situation.
5.1. trouble shooting
Symptom
The display on front
Panel does not light up.
No picture or sound.
Cause
The power cord is
Not plugged in
Wrong connection of
The Audio/Video output
Of the receiver to TV.
Audio muting.
TV power off.
Remedy
Check that the power cord
Is plugged in to the wall outlet.
Connect the Audio/Video
Output of the receiver to
TV correctly
Press the MUTE button.
Turn TV on.
No picture.
The receiver can’t
Receive the signal.
Incorrect values of some
Tuner parameters.
Wrong direction of
the dish
Check the antenna cable,
Replace the cable, or connect
The cable to the receiver tightly.
Set the values of tuner
Parameters correctly in
System set-up menu.
Check the signal strength
With a spectrum analyzer and
Adjust your dish correctly.
The remote controller
Does not working.
The batteries of the
Remote controller are
Not inserted or
Exhausted.
Check whether the batteries
Are inserted correctly in your
Remote controller.
Check the batteries, and if
Exhausted, replace the
Batteries of the remote
Controller.
5.2. Check point about badness STB
5.2.1. When nothing appears on TV screen
(1) Check the SMPS’s voltage
-
Power Connect(J6) -> pin3
: 4.75~5.25V
-
Power Connect(J6) -> pin10
: 10.2~12.6V
-
Power Connect(J6) -> pin11
: 21V~24V
-
Power Connect(J6) -> pin5
: 27V ~ 33V
-
Power Connect(J6) -> pin1
: 7.5~8.5V
-
Power Connect(J6) -> pin7
: 3.2~3.5V
Action) : If voltage is not normalcy, it change, and measure again SMPS
first. Still, SMPS is normalcy if voltage is low.There are
possibility that is badness with parts that use the voltage in
Main Board.
(2) Check the Power;
?
Pls. check whether you can have displayed message or not thru. RS232 SERIAL PORT terminal after power on, if not, you need to extend
your inspection to below point;
?
Pls. check whether you can have blinked Red LED, pressing
Front Key after Power on, if not, pls. replace MICOM(U7)
?
Pls. check whether you can have 3.3V input voltage of FLASH
ROM(U11), if checked 0V.
?
Pls. check U37, if notice input voltage level 1~2V.
?
If notice input voltage of Flash Rom 3.3V, pls. check below point;
?
Check the frequency value of R61 whether transmitted 27 Mhz, or
not thru. Oscilloscope
? If not transmitted 27MHz, pls. check X2
?
Check the frequency value of BD29 whether transmitted 54
Mhz, or not thru. Oscilloscope
? If not 54MHz, pls. replace SC2005
?
Pls. check whether sustain High voltage(About 3.3V) after
sudden transmitting of ROM Read cycle(Pulse) from PIN
No.26 on U11(39vf800A Flash ROM) when Power on/off.
? If not transmitting ROM Read cycle(Pulse), replace
SC2005.
? If
continuing
ROM
Read
cycle(Pulse)
without
termination, pls. re-test by re-touching Flash Rom, and
if notice the same phenomenon despite the former try
mentioned above, must replace Flash Rom .
?
RESET
Flash-Rom of Start Control Signal uses reset, chip-Select
--
?
Check Point : U11(12pin)
CE -?
Check Pint : U11(26 pin)
? If the flash-Rom(U11) not operation. , must be Checking
chip-select pin from SC2005. Replacement of part is
required. Because Reset and Chip-Select signal
is
not Booting. Also , Checking soldering or Chip is
consider flash-rom and CPU Where are replace of
component Part, and Check the insertion of part
(3) Check RS232 TERMINAL MESSAGE;
?
Pls. set up the test atmosphere with STB verified normal operation
?
Execute Hyper terminal on PC, and Setup as
follows;
Baud Rate: 115200BPS.
Data bit:8 bit
Parity bit :none
Stop bit :1
Control: none,
?
Connect STB and PC with RS232 CABLE, and see if have
message when Power ON/OFF.
?
Connect defective STB and PC with RS232 CABLE, and see if have
message when Power OFF/ON.
If not have Message,
?
Firstly AC power plug off, and then after pressing Menu & Plug
button, plug AC Power in again => (boot mode conversion)
? If not have any message on above configuration,
replace U11(39VF800A flash ROM).
?
If have “starting boot” Message on PC, pls. terminate Hyper
terminal at that stage, and then download Firmware fit for
Model thru. ITLINK.
?
When finishing Downloading, pls. set up by re-executing Hyper
terminal, and then plug in/off of STB.
?
If notice a screen on PC, you must do FACTORY RESET.
After FACTORY RESET, if you fail to notice Initialization screen
or face frozen screen, you must do re-soldering U16(EEPROM).
?
Check with output message;
?
If have below message or similar one, considered as normal
working.
(Output message would give difference upon Firmware
Version)

message
(“I2C
ERROR” ,”EEPROM ERROR”,”TUNER CONNECT FAIL”), Pls.
check resister value between U13 D17 and GND, B16 and
GND after AC power plug off, and if you have resistor value
20ohm~0 ohm, you must replace SC2005 (CPU).
?
If you notice “EEPROM ERROR” Message, Pls. replace
U16 :EEPROM(24C64) .
?
While do not run I2C signal, LEVEL of I2C signal(SC_SCL,
SC_SDA) must be 3.3V
?
If you notice “Tuner connect Fail “ Message, firstly check the
input power for Tuner, and then if O.K, pls. replace Tuner.
5.2.2. When “NO SIGNAL” message appears
(1) U5:(KA317(Regulator))-> pin 3 : 21V~24V
U5:(KA317(Regulator))-> pin 2 : 13V /18V
If confirm that voltage is measured and is not measured, U5 change
Action) : When U5's(KA 317) input voltage is low, do you change SMPS,
do U5 Voltage Line check in SMPS if change SMPS and is
low.
(2) Measure by Voltage Meter(Oscilloscope) whether VERTICAL(13Volt) or
HORIZONTAL(18Volt), 22KHz(ON/OFF) is displayed normally measuring
voltage of Q4's(TR: KSB772-Y ) Emitter when do SCAN
satellite in INSTALL MENU.
(LNB supply voltage check)
(3) When LNB voltage(13V/18V) is not displayed, it changes Q4(TR:KSB772-Y) if
13V/18V is displayed measuring Q4's(TR: KSB772-Y ) Emitter
- Vertical : 14V .
- 22Khz
Ho rizontal : 18V (Switching).
: On/Off (Switching).
(4) Voltage measurement supplied to TUNER
1. BD4 : about 5V,
BD5: about 28V ,
BD3 : about 5V
U3(Regulator) : 3.3V
Action) : If voltage is normalcy TUNER change .
(5) Check I2C Control Signal
Action) : if Voltage is drop SCL as well as SDA.
“ No Signal ”
message will
be
Display at TV Screen. therefore each of part check
have to
SCL with SDA of Voltage 3.2 ~3.5V. Check the install chipposition
and short of solder, cold solder, etc. Where are replace of
component Part, Check the insertion of part
SCL --?
SDA --?
(6) Changing SMPS test
(7) Try scan again after Factory reset
Action) : Do U11(39VF800A Flash ROM) and U13(SC2005) Re-solder
if “Wait to Reset setting” Message comes continually when did
Factory Reset. Still, change U11(39VF800A Flash ROM) if do not
become.
5.2.3. When do not act whether FRONT 7-SEGMENT(DISPLAY) acts strangely
(1) Change FRONT PANEL
(2) Change MICOM(U7) (AT89C51)
U7 : Confirm by SCOPE whether 11.0592 MHzs break out in pin 21
(3) Confirm by SCOPE whether 11.0592 MHzs break out in U7-pin 20, 21
5.2.4. When VIDEO screen gets into Scratch occurrence
(1) If scratch is happened on Video screen and Audio noise or stop phenomenon is
happened Tuner change .
(2) Audio is normalcy and if scratch is happened Video screen U10(SDRAM) change
(3)
When Video Color is badness, check below circuit
5.2.4. ERR0 CHECK POINT
(1) Change the MICOM(AT89C51).
(2) Check the supply voltage of SC2005(CPU).
?
Check the voltage : 3.3V
?
Check the voltage : 1.8V
(3) Check the supply voltage of flash ROM.
?
check the flash supply voltage : about 3.2V.
?
Check point U37 or Q18 if flash ROM supply voltage about 0~2V.
(4) Check the level of I2C line .
?
check the level of R66(SC_SCL). -> normal level ( 3.1V~3.3V).
?
check the level of R65(SC_SDA) -> normal level ( 3.1V~3.3V).
4.3 Check the supply voltage to TUNER if either R40 or R41 is low level (0v~2).
4.4 Change the TUNER unit if the TUNER supply voltage is normal state.
4.5 Maybe CPU problem if same condition after changed the TUNER.
