Symptoms and Correction

The display boards of PC no image in DVI.
Reason and Resolve: If some display board of DVI cannot receive the data when turning on the TV, there is no output; if pull out the DVI line abruptly, there is also no DVI output; Before starting PC, connect the DVI line with LCD TV steadily, So DVI can receive the correct date from DDC­ Display
Data Channel­ when turning on the TV,DDC is in chassis 24LC21.

No picture but sound, on LOGO when turning on the TV, poor light is bright.
Reason and Resolve: Check the connect line in up screen, and connect the line

No picture no sound ,no snowflake in TV condition, but AV is normal.
Reason and Resolve: Check the outside of RF(also bus and power supply), there is no problem ,but no output from RF, so the RF is disabled.

LCD TV cannot be controlled.(inc red lamp is no but the TV is off, remote control and key press in TV cannot control the TV etc.)
Reason and Resolve: The LCD TV cannot work abruptly, power off and turning it on again.

Factory menu display.
M

Index: 1
HWUC_BRI 0x1F
The M denotes entering into factory mode now, the figures of index denotes the index number now, the HWUC_BRI denotes the name of adjusting item now, the 0X1F denotes the numerical value.
