A. MT29F2G08ABAEAWP (U107)
Description
Micron NAND Flash devices include an asynchronous data interface for high-performance I/O operations.
These devices use a highly multiplexed 8-bit bus (I/Ox) to transfer commands, address, and data. There are five
control signals used to implement the asynchronous data interface: CE#, CLE, ALE, WE#, and RE#. Additional
signals control hardware write protection and monitor device status (R/B#). This hardware interface creates a
low pin-count device with a standard pinout that remains the same from one density to another, enabling future
upgrades to higher densities with no board redesign. A target is the unit of memory accessed by a chip enable
signal. A target contains one or more NAND Flash die. A NAND Flash die is the minimum unit that can
independently execute commands and report status. A NAND Flash die, in the ONFI specification, is referred
to as a logical unit (LUN). There is at least one NAND Flash die per chip enable signal. For further details, see
Device and Array Organization. This device has an internal 4-bit ECC that can be enabled using the GET/SET
features or by factory (always enabled). See Internal ECC and Spare Area Mapping for ECC for more

A. USB HUB CY7C65642 (U108)
Description
HX2VL is Cypress’s next generation family of high- performance, very low-power USB 2.0 hub controllers.
HX2VL has integrated upstream and downstream transceivers; a USB serial interface engine (SIE); USB hub
control and repeater logic; and transaction translator (TT) logic. Cypress has also integrated external
components such as voltage regulator and pull-up/pull-down resistors, reducing the overall BOM required to
implement a USB hub system. The CY7C65642 is a part of the HX2VL portfolio with four downstream ports
and an independent TT dedicated for each downstream port. This device option is for low-power but high-
performance applications that require up to four downstream ports. The CY7C65642 is available in 48-pin
TQFP and 28-pin QFN package options.

13. SOFTWARE UPDATE
A. MAIN SOFTWARE UPDATE
In MB98 project, please follow software update procedure:
1. mb98_en.bin, RomBoot.bin, PM51.bin and usb_auto_update_D7L.txt documents should be copied directly
inside of a flash memory (not in a folder).
2. Insert flash memory to the TV when TV is powered off.
3. While pushing the OK button in remote control, power on and wait. TV will power-up itself.
4. If First Time Installation screen comes, it means software update procedure is successful.

14. TROUBLESHOOTING
A. NO BACKLİGHT PROBLEM
Problem: If TV is working, led is normal and there is no picture and backlight on the panel.
BACKLIGHT_ON/OFF pin should be high when the backlight is ON. Collector pin of Q106 must be low when
the backlight is OFF. If it is a problem, please check Q106 and the panel cables. Also it can be tested in TP33 in
main board.
Dimming pin should be high or square wave in open position. If it is low, please check S108 for Mstar
side and panel or power cables, connectors.
Backlight power supply should be in panel specs. Please check Q124, shown below; also it can be checked
TP42.
44
Page 46
STBY_ON/OFF should be low for TV on condition, please check Q102’s collector.
B. CI MODULE PROBLEM
Problem: CI is not working when CI module inserted.
Possible causes: Supply, suply control pin, detects pins, mechanical positions of pins.
CI supply should be 5V when CI module inserted. If it is not 5V please check CI_PWR_CTRL, this pin
should be low.
45
Page 47
Please check mechanical position of CI module. Is it inserted properly or not?
Detect ports should be low. If it is not low please check CI connector pins, CI module pins.
46
Page 48
C. STAYING IN STAND-BY MODE
Problem: Staying in stand-by mode, no other operation.
This problem indicates a short on Vcc voltages. Protect pin should be logic high while normal operation. When
there is a short circuit protect pin will be logic low. If you detect logic low on protect pin, unplug the TV set
and control voltage points with a multimeter to find the shorted voltage to ground.

Page 50
E. KEYPAD TOUCHPAD PROBLEMS
Problem: Keypad or Touchpad is not working
Check keypad supply on MB98.
F. USB PROBLEMS
Problem: USB is not working or no USB Detection.
Check USB Supply, It should be nearly 5V. Also USB Enable should be logic high.
49
Page 51
G. NO SOUND PROBLEM
Problem: No audio at main TV speaker outputs.
Check supply voltages of 12V_VCC, VDD_AUDIO and 3V3_AMP with a voltage-meter. There may be a
problem in headphone connector or headphone detect circuit (when headphone is connected, speakers are
automatically muted). Measure voltage at HP_DETECT pin, it should be 3.3v.
50
Page 52
H. STANDBY ON/OFF PROBLEM
Problem: Device can not boot, TV hangs in standby mode.
There may be a problem about power supply. Check main supplies with a voltage-meter. Also there may be a
problem about SW. Try to update TV with latest SW. Additionally it is good to check SW printouts via
Teraterm. These printouts may give a clue about the problem. You can use Scart-1 for terraterm connection.
İ. NO SİGNAL PROBLEM
Problem: No signal or Low signal in DVB-S/S2 mode.
Check signal cables and LNB voltage, if there is no problem, check RS6000 supply voltages;
3V3_SAT_VDDA1, 3V3_SAT_VDDA, 3V3_SAT_VDD and 1V3_SAT_VCC.
If the above measurements are OK, then measure the voltage from the PIN1 of U90.
If the PIN1 voltage is equal to 0V, please check i2c waveforms and software. If the PIN1 voltage is lower than
1V(e.g: 0.8Vor 0.3V), change the U128 with a new part.
