manual abstract


- Find the “G2 – SCREEN” item in service mode. - Adjust screen volume (on FBT) to bring the cursor to central position(Green). 3.7.2 WHITE BALANCE - Select a dark picture and adjust RED BIAS and GRN BIAS to the desired colour temperature. - Select a bright picture and adjust RED, GRN and BLUE GAIN to the desired colour temperature. 3.7.3 FOCUS Adjust the Focus volume (on FBT) to have the best resolution on screen. 3.7.4 VERTICAL GEOMETRY Adjust V. LINEAR (linearity), S CORRECT (S. Correction), VERT SIZE (Vertical amplitude), VERT CENT (vertical centring) to compensate for vertical distortion. 3.7.5 HORIZONTAL PICTURE CENTRING Adjust HOR CEN (Horizontal centre) to have the picture in the centre of the screen. 3.7.6 EAST / WEST CORRECTION Adjust the PARABOLA, HOR WIDTH, CORNER, HOR PARAL, EW TRAPEZ, to compensate for geometrical distortion. HOR PARAL DTV R&D Europe CP-520/520A/520F Service Manual HOR WIDTH adjust for 93% overscan. PARABOLA CORNER B & CORNER T EW TRAPEZ 3.7.7 AGC - Make sure option bits are correct for the tuner fitted on the chassis (See above how to change option bits). - Adjust the antenna signal level at 62 dBmV - Tune a colour bar pattern. - Find the “AGC” item in service mode. - Press the key “OK” on the remote keypad and wait until AGC level stabilise to the optimum value. - Alternatively, use “Vol Up/Dwn” keys to adjust manually to the desired Tuner Take Over Point (TOP).
