Question about Durabrand DU1901 TV
Your TV is telling you that the cable, antenna, or another input has no signal coming into it. When there is no signal, the set mutes itself to a blue screen to avoid your seeing "snow" on the screen. You need to check your connections. IF all are O.K., then your problem must be in the tuner or A-V input. Stargazer
