Grating in dark area, the cause of the problem, it is a bad picture tube, the second is bad deflection coil. Tube produced adverse transient area is fixed, and the dark space generated by the deflection coil bad will move according to the deflection coil rotation. GRRservice manual download site

(2) measuring deflection coil resistance, line deflection is 1.8 Ω, field deflection is 60 Ω, essentially normal. GRRservice manual download site
(3) use substitution method, after changing the deflection coil fault elimination.GRRservice manual download site
