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 Cause Remedy

The display on front Panel does not light up.

The power cord is Not plugged in

Check that the power cord Is plugged in to the wall outlet.

No picture or sound. Wrong connection of The Audio/Video output Of the receiver to TV. Audio muting. TV power off.

Connect the Audio/Video Output of the receiver to TV correctly Press the MUTE button. Tum 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(front panel display “0000”)

(1) Check the SMPS’s voltage

- Power Connect(J2) -> pin4, pin5 : 4.75~5.25V

- Power Connect(J2) -> pin6 : 10.2~12.6V

- Power Connect(J2) -> pin3 : 21V~24V

- Power Connect(J2) -> pin1 : 27V ~ 33V

- Power Connect(J2) -> pin7 : 7.5~8.5V

- Power Connect(J2) -> pin9, pin10 : 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) Confirm by Oscilloscope whether 27 MHz break out in R10 and R11.

Action) : if 27Mhz do not break out, X1(27Mhz CRYSTAL), or

U6(74LCX04) change .

(3) ROM Read cycle(Pulse) should be happened continuously through

Oscilloscope at Power off/on in pin 26 of U2(39vf800A Flash ROM).

(If U2's pin 26 is 3.3V by Voltage Meter, it is normalcy)

Action) : if U2-pin26 is measured (0V ~ 2V) by Voltage Meter,

U2(39VF800A FLASH ROM) change, still, change U1(L64108

CPU) if do not act.

(4) Flash-Rom of Start Control Signal uses reset, chip-Select

RESET --à

Check Point : U2(12pin)

CE --à

Check Pint : U2(26 pin)

Action) : If the flash-Rom(U2) not operation. , must be Checking chip-select

pin from L64108. 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

(5) Confirm that Message is displayed when interlink STB and PC by RS232

CABLE and did Power off/on

Execute Hyper terminal in PC and do together Setup with next time

Baud Rate: 115,200bps.

Data bit:8 bit

Parity bit :none

Stop bit :1

Control: none

1) When Message is not displayed:

1. Do AC Power put on in state that click Menu and Select key

simultaneously after AC power put off, (method by boot

mode Booting) Still, if any message is not displayed, it

changes U2(39VF800A flash ROM)

.

2. if “starting boot” message is displayed, Do Download again

by suitable Firmware to model.

3. Do STB Power off/on after Download is completed.

4. If screen is displayed, it does FACTORY RESET necessarily.

2) When Message is displayed:

(Message can be different according to Firmware Version)

1. When “I2C ERROR” ,”EEPROM ERROR”,”TUNER CONNECT

FAIL” message happens After AC POWER OFF, measuring

resistance between U1's pin 156 and GND, pin 155 and GND, if

it is measured (20ohm ~ 0 ohm), L64108 ( CPU ) must change.

2. When “EEPROM ERROR” Message happens

U4 : EEPROM(24C64) change

3. When “Tuner connect Fail” Message happens

If POWER supplied to Tuner is normalcy, Tuner must change.

4. When “ FLUSH DRAM ” Message happens

U7(L64005) and U8(KM416S1020) Re-soldering do, and

change U7(L64005) if is happened again.

5. Normal Message as being displayed, change MICOM if TV screen

does not come

5.2.2. When “NO SIGNAL” message appears

(1) U19:(KA317(Regulator))-> pin 3 : 21V~24V

U19:(KA317(Regulator))-> pin 2 : 13V /18V

If confirm that voltage is measured and is not measured, U19 change

Action) : When U19's(KA317) input voltage is low, do you change SMPS,

do U19 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 F100's Lead(or Tuner LNB OUT PORT) when do SCAN

satellite in INSTALL MENU.

(LNB supply voltage check)

(3) When LNB voltage(13V/18V) is not displayed, it changes Q27(TR:kta1273) if

13V/18V is displayed measuring Q27's(TR:kta1273) Emitter monad by

Voltage Meter and measure whether 13V/18V is displayed in F100(Poly

Switch)

Action) : If mania is happened to F100 or Q27 after shift Tuner shift

(4) Voltage measurement supplied to TUNER

1. L13(Coil) : about 5V,

L14(Coil): about 28V ,

U12(Regulator)-Pin 3 : about 5V

(E54(+)Elect Cap ) : 3.3V

Action) : If voltage is normalcy TUNER change .

2. U12(Regulator)-Pin3 : 3V~ 0V

Action) : If it is 100 ohm lows, doing AC POWER OFF and measure

U12's(Regulator) 3Pin and resistance between GND,

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 chip-position

and short of solder, cold solder, etc. Where are replace of

component Part, Check the insertion of part

SCL --à

SDA --à

(6) Changing SMPS test

(7) Try scan again after Factory reset

Action) : Do U2(39VF800A Flash ROM) and U1(L64108 CPU) Re-solder

if “Wait to Reset setting” Message comes continually when did

Factory Reset. Still, change U2(39VF800A Flash ROM) if do not

become.

5.2.3. “CI CARD INITIALIZING NOW….” Message becomes Display continually on screen and

when Menu transfer is slow Firmware again Download do .

5.2.4. When do not act whether FRONT 7-SEGMENT(DISPLAY) acts strangely

(6) Change FRONT PANEL

(7) Change MICOM(U10) (AT89C51)

U10 : Confirm by SCOPE whether 11.0592 MHzs break out in pin 21

(8) Confirm by SCOPE whether 11.0592 MHzs break out in U10-pin 20, 21

5.25. 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 U7 : (L64005)

U8 : (km416S1020 sdram) change

(3) When Video Color is badness, U11 : (BT864) change.

(4) After Power ON, when that stop screen phenomenon happens U13 : (AKM4323) change

(5) Video Filter from Bt864A (Digtal Video Encoder)

Action) : If the Color signal is not operation. Shoud be Checking

43pin(SYSCLK) 27Mhz Of U11 and VCC(3.3V) if you have

checking, If No problem. Check the install chip-poistion and short of

solder, cold solder, etc. Where are replace of component Part, Check

the insertion of part
