Phenomenon 1˖The LCD can not lightDŽ
Possible reasons˖
a. Are the Main Board power okDŽ
b. Are the Main Board work DŽ
c. Are the Backlight ˄24 V˅socket inserted goodDŽ
d. Does the output 24V backlight power normalDŽ
e. On board back light control plug (CN20) whether inserts.
Phenomenon 2: Main board can not work normally
Are there short-circuit phenomenon or not good weld on the Main Board˄mainly look whether
the surrounding circuit of the FLI8532 and FLASH(U29) is short-circuit or not good weld ˅DŽ
a. Whether all power on the Main Board (U17, U22, U8, U24, U18) is normal
b. FLASH chip may be badDŽ
c. DDR chip ˄U15ǃU16˅may be bad .
Phenomenon 3˖have VGAˈno HDMI
a. Examine whether the power supply of ANX9021 is normal ˄U5ǃU7 have the output
voltage˅DŽ
b. Whether the input of the HDMI have signal DŽ
c. Examine whether the 27M clock signal of the ANX9021 chip to detect is normal
d. Examine whether the circuit of the ANX9021 chip is normal.
e. Examine whether the circuit of the U4 and U32 chips are normal.
Phenomenon 4˖there is no picture˄no LOGO picture˅
a. Examine whether the power supply of Main Board is normal
b. Examine whether the Main Board does work.
c. Examine whether FLI8532 clock is normal output
d. Examine whether LVDS signal jack is good.
Phenomenon 5˖ Picture is good,sound is not good
a. Examine whether power supply of Analog Board is normal.
b. Examine whether speakers is good
c. Examine whether the Analog Board is Xu Han phenomenon or short-circuit.
Phenomenon 6˖The sound is good,but the picture is bad
a. Examine whether the Backlight power supply (24V) output is normal
b. Examine whether the on/off signal is high.
c. Examine whether signal line is good.
d. Examine whether 12V supply is normal.
e. Examine whether the LVDS chip output signal is normal.
Phenomenon 7˖VGA is not picture.
a. Examine whether VGA socket is normal
b. Examine whether PC is open
c. Examine whether U2 surrounding circuit chip is normal.
d. Examine whether U3 chip output signal is normal
Phenomenon 8˖ VGA is good,pictures of YPBPR and USB is bad
a. Examine whether the PI5V330 IC(U1) is normal
b. Examine whether YpbPr, USB input signal is normal
Phenomenon 9˖
The picture of YPBPR is good but USB is not good.
aǃ Examine whether the 5pin UA7 is low. signal
bǃ Examine whether UA7 is 5V output UA7.
cǃ Examine whether U1,U2 of HDTV USB Voltage Power Supply is normal.
Other˖Switch on powerˈif 12V is low, The main reason is the power to the main board is a
short circuit
