3) Output Circuit
The output circuit make two convergence correction currents flowing 4H and 4V coils which are constructed on
the deflection yoke. These output circuits are similar to the other. The following description is 4V output circuit.
The digital signals which are output from IC8U1 are converted to the analog signal(4V) at MR8U2 and input
to IC8P2 through IC8W2.The signal(YSC) which is output from DSP(IC501) is changed DC level and swing
at R8N2,R8N3 and R8N4 and then input to IC8P2.These signal(4V and YSC) are mixed at IC8P2 and input
to IC8P1.R8R7 and D8R3 are slice circuit for preventing over current and keep the input voltage at IC8P1
within -0.7V to +0.7V. At IC8N1 the input voltage is converted to the current flowing correction coil on CRT.
