Please does anyone have the circuit diagram of SONY TV
Model number: KV-J21MN1 21” colour tv with NICAM and german A2 stereo. The parts of the T.V. are I.F I.C. is TDA 8375A, Remote control microprocessor I.C. is CXP 85224A, Nicam stereo processor I.C. is MSP 3410B-PP-F7, S.M.P.S I.C. is STR S6707, Vertical o/p I.C. is LA 7830, and another I.C. TDA 8424.

I had removed approx 20 resistors near the tuner for resoldering, as their solder points had developed cracks and had removed them to clean the lead and resolder with fresh solder. I had noted down the resistor values, and resistor numbers, but I have made a mistake in noting down values of 5 resistors. I do not know which points the 5 resistors have to be soldered.

Please help me as the TV set was in working condition. The TV set was purchased in 1999 in India. My EMAIL I.D. is tejasnaidu@yahoo.com
