my tv went off last night,the same.i tried to turn it on but black screen,no sound and flashing stand buy light.i was an electronics tester/builder for years,so i whipped the back off checked all the internal fuses mine had 2 fuses but they where ok.i noticed with the back off i could hear a clicking sound comeing from the ht coil,very danger area do not touch,about 25 thousand volts.so im asumeing its the tube gone.and am soon binning it for a newer flat screen lcd tv for about 100 pounds from your local tesco shop.cheers gary jenkins,cambridge.
