my uncle threw out a techwood 32884 HD digital tv
because when he switches it on the red light keeps going off
I now have the tv can you please help me
You need a sighal source. It can be an antena, a satelite dish or a cable box.
Make sure that you have one connected. If it's a cable box, it also need to be turned on.
Also, does your uncle still have the user manual?

"when he switches it on the red light keeps going off"
As far as In know, that is normal behaviour for most TVs. When the TV is "off" (on standby) there is a pilot light showing, which goes off when the TV comes out of standby.
Would you like to be a little more forthcoming with your fault description.
Assume we have absolutely no idea what you are on about. Because we don't until you tell us.
