3) Chang a good fan.
4) If the fan can not turn yet after the above operation, chang the mainboard.
8. The color of TFT is abnormal
1) Check whether the video output of rear zone is normal.
2) If the video output of rear zone is normal, that is to say the decode works
normally, and you should check the connection between the mainboard and the
TFT unit.
3) If the video output of rear zone is abnormal, change the mainboard part.
4) If the color of TFT is abnormal yet after the above operation, change the video
driver board part.
9. White screen
1) Check the connection between the loader and the mainboard, the mainboard
and the power supply board of TFT, the power supply board of TFT and the TFT.
2) If the trouble is still not solved, change the power supply board of TFT.
3) If the trouble is still not solved after the above operation, change the Display
part.
10. Black screen(No display in the TFT)
1) Check the connection between the loader and the mainboard, the mainboard
and the power supply board of TFT, the power supply board of TFT and the TFT.
2) Check whether the background lights are illumed. If not, change the CCFL
board.
3) If there is no display in the TFT, change the display part.
4) If there is still no display in the TFT after the above operation, change the
mainboard part.
11. Blue screen
1) Check whether the video output of rear zone is normal.
2) Check whether the source can normally change. And have sound output
3) If yes,check the reverse detect line.
4) If not, change the mainboard part.

3
5) If not yet, change the video driver board part.
12. The icon of MUTE displays in the TFT at all times
1) Check whether there is any audio output.
2) If the audio output is normal, change the mainboard part. If the trouble is still not
solved, change the display part.
3) If the audio output is abnormal, change the mainboard part. If the trouble is still
not solved, change the loader part.
13. Beeper function failure
1) Check whether the beeper has turn off in the setup option.
2) Change the beeper.
3) If the trouble is not solved yet, change the mainboard part.
14. Key function failure
1) Check whether the key in the front panel is available.
2) Check the connection between the front panel and the mainboard. If necessary,
change the FFC connector.
3) If the key in the front panel is void, change the front panel part.
15. Remote controller function failure
1) Check whether the key in the front panel is valid.
2) If the key in the front panel is valid,that is to say the mainboard works normally.
Check whether the battery of the remote controller is available or change
another one good.
3) If the key in the front panel is viod, you should check the connection between the
front panel and the mainboard. If necessary, change the FFC conector.
4) If the trouble is still not solved yet, change the front panel.
5) If the trouble is still not solved yet, change the mainboard part.
16. No display in the LCD
1) Make sure the TFT unit is colsed.
2) If there is no display in the LCD also, you should change the LCD board.
17. Display in the LCD is abnormal

2) If the display of LCD is abnormal, you should change the LCD board.
18. No volume display in the TFT
1) Check whether the volume knob is available.
2) Check whether there is volume display in the TFT using the remoter controller to
adjust the volume.
3) If there is volume display in the TFT using the remoter controller to adjust the
volume, that is to say the display part and the mainboard part work normally, you
should change the front panel part.

4
4) If there is no volume display in the TFT using the remoter controller to adjust the
