Common fault of LCD screen
* Bright line or bright belt (BL): constant longitudinal or transverse illuminating line or belt due to non-conformed connection between IC and glass
* Dark line (DL): constant longitudinal or transverse illuminating line due to non-conformed connection between IC and glass.
* White panel (WP): only light tube illuminates owing to non-conformed drive plate of the LCD, without any display signal in the display area, and the whole screen is white.
* Screen breaking: (overflow of LCD): with damage or invisible damage of the liquid crystal glass, irregular black defect occurs from liquid crystal body to glass and polarizer, which can not be seen at any image. The overflow portion can not form image and does not display.
* Pressing Scrape (PS): after local display area at the front of LCD is heavily pressed, glass of the pressed portion is not damaged, the liquid crystal body can not display normally, with spot or block black defect.
* Screen mess: irregular color display arising from damage of driving plate in LCD.

Service mode entry procedure [Factory mode]
Factory menu entry: Press MENU, and then press 1999
Troubleshooting
Procedure
No power
Protection or without light (refers to
the disappearance of image several seconds after the emergence of image) /
White panel.
White screen after power-off (work
normally when power on, but when power-off or no signal input, the screen shows
a white screen) / TV without channel or with color cast.
Poor sound / No VGA input signal
Poor embedded power supply of TV
Software [Firmware] upgrades procedure. MSD6308 Program Software Burning Instruction
Connect burning board and computer; connect burning board and
waiting burning main board VGA socket with VGA connecting wire.
Running, if the hint is driver should be installed for burning
board.[see the figure below for details]
Click Help in the toolbar, when pop up Present, click the first
item.
Sorting set the burning board terminal and computer interface
make sure the two are all set as automatic connecting.
Click view in toolbar in the main menu, click the second ( count
backwards) view in main toolbar and the second(count backwards) “ Eagle NAND
Program” to get into the next menu.
When toolbar shows：Success .Please reset
power. That means burning finished (Note: Although the hint shows complete but it may not be burning completed, wait for 5 minutes to
shut off power. If U disk cannot be used for upgrading.). For burning, boot file should be burning
again until U disk can be used for upgrading）
Main board software upgrades.
1,U disk plugged into main board , put MstarUpgrade.bin software into formatted U disk , press and hold on VOL + key button on TV key board, after about three seconds , LED starts flashing , wait until LED lights no longer flashing and steady mean burning success. If press three seconds, LED lights (no flashing
into place) then boot files should be burned.
2, after prompting success, then click POWER on button panel to check whether main board can be starting on, if it can be started on means burning success, otherwise as unsuccessful.
