Call up the"AFC ALIGN" service menu (press and hold the button . . 3 seconds while switching the TV on). With 2 select the menu item "AFC ALIGN". The button 4 or 3 activates the automatic AFC alignment function. The AFC average value is stored in IC 830. 5a. Activation of AFC reference . –> OK –> 6 –> 6 –> 4 or 3. AFC "ON" / "OFF". On activation of AFC Reference a rectified IF-voltage is measured at the AFC output of the IC150-(9) which is used on station search as a comparative value for VCRRF playback (station identification "AV") to readjust the modulator drift. 6.Tuner AGC Feed in a standard test pattern at a channel in the upper range of the UHF band and store it at programme position 1. RF .1.5mV (64dBmV, noise-free picture). Switch the TV off with the power button. Voltmeter: tuner contact 2. Call up the Service Menu (press and hold the button "6" for . 3 seconds while switching the TV on). With 2 select the menu item "AGC ALIGN". With the 4and 3buttons tune the station so that noise just starts to appear in the picture. Then reduce the value so that the noise just disappears from the picture. Terminate with "6". or: With the button 4or 3. set the voltage to 3.3V ± 0.4V. 7.White balance Feed in a FuBK test pattern. Set the colour contrast (E) to minimum. Set the contrast (W) to maximum. Adjust the screen brightness (R) so that the gradation from the darkest grey scale value to black is just still visible. Set the controls VG and VB on the CRT panel so that no discolouration is visible in the grey scale. 3 - 2 GRUNDIG Service CUC 7301 F Schemas electriques / Circuit Diagrams CUC 7301 F Schemas electriques / Circuit Diagrams (button) CUC 7301 F Schemas electriques / Circuit Diagrams CUC 7301 F Schemas electriques / Circuit Diagrams Travaux de maintenance Voir alignements page Servicing work after replacing see alignment page 3-2 ( BB639 CD2092 BB545 CD2036 BB639CD2096 BB545CD2066BB545CD2051 B10P CD2077 BB640CD2123 BB639CD2078 BB545 CD2181 BB640 CD2189 BB639CD218818kCR2188 18kCR2182 1kCR2181 470kCR2136 47 CR2142 47 CR2141 10kCR2138 3,3kCR2101 3,3kCR2031 18kCR2096 18kCR2097 18kCR203847kCR2046 18k CR2115 22CR2125 18kCR2124 3,3kCR2071 47k CR2084 18kCR2077 3,3 CR2122 22CR2086 18kCR2078 15CR2111 18kCR2151 47k CR2109 18kCR2123 18kCR211718kCR2112 15 CR2113 8,2kCR2102 10k CR2026 18kCR2106 18kCR20560 CR2058 18kCR2098 220CR2121 3,3CR2087 10 CR2089 18kCR2079 68 CR2190 68 CR2195 10k CR2146 0CR2057 18kCR2192 10kCR2139 18kCR2119 18kCR2118 18k CR2191 10k CR2187 1,2p CC2048 6,8p CC2064 100pCC2188 * CC2194 100p CC2181 8,2pCC2056 1nCC20581nCC2059 1nCC2154 8,2pCC2053 15p CC2143 100p CC2067 10nCC2135 10nCC21113,3pCC2101 1nCC2097 2,2p CC2089 470p CC2098 470p CC2099 82pCC2096 270pCC2091 * CC2182 10n CC2192 470p CC2041 100p CC2031 1nCC2085 4,7pCC2124 10nCC2125 47p CC2042 3,3pCC2036* CC2037470pCC20471nCC2043 1nCC2084 0,47p CC2121 1nCC2123 1n CC2126 10nCC2122 1n CC2072 10nCC2113 * CC2081 10nCC2168 270pCC2078 1nCC2076 10nCC2086 10n CC21931,5p CC2191 1,8p CC2189 2,2p CC2187 2,2 CC2186 2,2p CC2184 2,2p CC2183 1,2p CC2179 1,2p CC2178 1n CC2152 39nCC2153 1n CC2102 10n CC2118 100p CC2066 100pCC2142 100pCC2141 10nCC2138 470p CC2107 47p CC2006 120p CC2007 1,2p CC2177 1,2p CC2176 470p CC2129 470p CC2128 10nCC2139 1nCC2155 6,8p CC2063 120pCC2005 470pCC2167 10n CC2174 * CC2190 1n CC2039 470pCC2170 1nCC2151 0,5p CC2185 0,5pCC2175 1nCC2065 1nCC21561nCC21581nCC2162 1nCC2049 10nCC2106 10nCC2112 1,2p CC2051 10nCC2119 470p CC2127 10nCC2136 10nCC2131 10nCC2133 1nCC2134 10pCC9003 10pCC9002BB640CD2121 B11P CD2124 BB640CD2103 B10P CD2104 BA592 CD2031 BA592 CD2071 BA592 CD2101 470 CR2135 4MHz Q2143 DruckDruck Druck TEST VSSA2A1A0 SCL SDA VCC 1 2 3 4 5 6 7 8 X24C01 CIC2120 31 BUFFERS B1B3B5B7 + + + + - - - - COMP PHASE 2 VOLT.
