Question about Symphonic SC313D 13 in. TV/VCR Combo
1]...Please check that the sleep timer function is not set;
2]...Some tv's have a count-down timer & switch off if there is no signal input, either from the tv aerial, or av input;
Please check that the aerial is plugged in to the correct socket on the rear of the tv; test the aerial in another tv, to make sure it is working ok.
3]...It could be a problem with the remote/teletext panel?
for example, switching unexpectedly to standby, or changing channels unexpectedly?
4]...It could be a power supply fault;
for example, switched mode power supplies (SMPS) can cause problems; this could also cause the set to switch to standby mode.
If the unit still switches off after 1 minute, even after checking the tv aerial is functioning properly, & is connected to the tv unit aerial socket ok, & the source is set to the tv aerial, then this could be indicative of an internal fault.
TV sets contain extremely high & very dangerous voltages, even after the tv has been unplugged from the ac power socket, on the wall, which could kill you!
FOR THIS REASON, & FOR YOUR SAFETY PLEASE DO NOT attempt to open or repair the tv unit yourself, unless qualified to do so - please take it to the tv repair shop;
only qualified tv engineers should attempt to carry out tv repairs.
I hope this information was helpful for you.
