DESCRIPTION OF BLOCK DIAGRAM 1. Video Controller Part(GM5020). This part amplifies the level of video signal for the anolog to digital conversion and converts from the analog video signal to the digital video signal using a pixelclock. The pixel clock for each mode is generated by the PLL. The range of the pixel clock is from 25MHz to 135MHz. This part consists of the Scaler and frame buffers which converts frame rate of input signal to 60Hz frame rate.

EMI components. This part contains of EMI components to comply with global marketing EMI standards like FCC, VCCI CISPR, the circuit included a line-filter, across line capacitor and of course the primary protection fuse. 2.
ADJUSTMENT 1. Application This specification shall be applied to the adjustment and inspection of the LN801H. 2. Adjustment Setup All adjustment are thoroughly checked and corrected when the monitor leaves the factory, but sometimes several minor adjustment may be required. Adjustment should be following procedure and after more than 30 minutes. Unless otherwise specified, adjustment shall be carried out under the following conditions.
3. Adjustment 3-1. Initialization and Aging Prior to adjustment of this model, more than 30 minutes of aging shall be carried out. 1) Display any pattern at any Mode. 2) Run adjustment program for LN801H on the IBM compatible PC. << DIST.
