Use White Balance (White Black) pattern Acces to Service Mode. a. For IC Micom HBM-00-08 : - Make 1 horizontal line (raster tip) by pressing yellow button on remote control. - Set trimpot G2 until we got 1 horizontal line with enough intensity and notice the domi nance color. - return to the normal position by pressing yellow button. - Adjust trimpot G2 until we got voltage on cathoda dominance as bellow : - For 21" Real Flat - For 20" and 21" = 136Vdc ± 1Vdc = 130Vdc ± 1Vdc
b. For IC micom HBM-01-04 : - Measure the third cathode (KB, KG, KR) and look for cathode with highest value. - Set trimpot G2 until voltage on highest cathoda as bellow : - For 21" Real Flat = 136Vdc ± 1Vdc - For 20" and 21" = 130Vdc ± 1Vdc - Use Chroma meter for White Balance Adjustment. - Plug in Chroma meter probe on the black side. - Adjust R & G DC, to get standard value : x = 264 ± 5
y = 256 ± 5 Y = 1.8 s/d 5 - Press menu button to save data Adjustment.
