- Reduce Volume to Minimum [0].
- Press "Mute' key, then press {9,7,3,5} by remote control.
- Press (►) key to enter the sub-menu, and press "Menu" key to return to Main Menu.
ANALOG BOARD SOFTWARE UPDATE
- Connect PC, update board, and J3 on the main board with serial line.
- Provide the STB +5V for main board.
- Open "MtkTool.exe" in MTK TOOL program, and set the parameter as below.
- Press "Browse" for selecting the SW.
- Press 'Upgrade" to download the SW. It will be OK when it show 100%.
- After downloading SW, it will be long time for Initializing EEPROM.
SOLUTION-2
- Preoperative is same as above.
- Set SYSTEM -> Factory key on Factory Menu to OFF.
- Connect the device as below.
- Update the SW follow solution (3), (4), (5), (6)
- LCD32MT01M1 is designed for Europe, using 32 inch CM1 panel. The main chip is MTK8201. Support 1x RF in, 0.5x SCART, 1XSCART, 1xYPbPr, 1xVGA, 1xside AV include YC input, 2xHDMI,1x headphone out, 1xDVB-T input.
DIGITAL MODULE SERVICING AND DEBUG HINTS
Check PCB and each section power supply:
12V, 5V, 1.2V,1.8V ,3.3V.
Switch on the power, then measure the signal
of output port of video and audio. If
no output, check the following point:
1) video output of CPU section.
2) 4Mhz clock of the tuner output
3) Output of chip 74AHC1GU04( position U24 of
schematic). 4Mhz clock signal to CUP(PNX8314).
4) Signal of SDRAM and flash chip when working
.
5) Audio DAC ( component’s position U6 of schematic.
Enter the menu’s manual research item, and set appointed channel number, check the
signal indicator on TV screen.
Normally there is a signal level display on
the menu. If no displaying for the signal state indicated
information, check the following point:
1) 4Mhz clock signal of the tuner output,
2) Output of chip 74AHC1GU04(component’s position U23 of schematic).
3) Else channel decoder schematic section.
4. When it display the signal state indicated
information, Press “OK’ button, and research program.
It will not play
the program if not get the program list. Check: components of the TS
output from TDA10046 to CPU.
Inset the CAM card( PCMCIA CARD) to CI
connector, the integrated system will detect it. if system has not found it,
please check:
1) Input clock of Chip CIMAX SP2, The clock
outputs from XD1 (component XD1 of schematic) to chip CIMAX SP2.
2) Components and schematic of CI section.
If not communication from ATV to digital module, check: I2C of the ATV( MT01 section) and digital module.
