I've been trying to rectify a fault on ferguson tv(25inc), model no;d59f. the nature of the fault is; the tv always switches itself off an on ,after sometime( with shrill noise from the line transformer ), especially when connected to the aerial and tv station very bright. i have removed the boost capacitor in the power supply with known good one,but the problem still continue.i observed that when the tv is not receiving broadcast signal,it will not switch off. i've injected a video signal throughthe av input(bypassing the tuner), the result is still the same.Arching is observed in the line transformer ,with vertical dark line streaks when the tv is about to swich off.What could be the cause of this?
