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.
