TC - 33 gf85r for panasonic M18M movement, first observed this machine in the condition of no signal blue screen grating on also has a bar, but for black, dark and grating left, and in the AV state still has this phenomenon, through the analysis of the circuit to determine failure to apply for the clamping circuit in blue, the movement of red, green, blue three colors clamping circuit processing IC for TC3401 (TA8889AP), measuring IC3401 (11) voltage is 2 feet. 4 v, discovery and normal 5. 4 v deviation is great, blue for clamping the IC (11 feet) filter, external C3401 capacitance, capacitance value of 50 v / 0. 1 mf removed C3401 found the capacitance has gone mouldy, replace the same capacitance, troubleshooting.dbMservice manual download site
