SOURCE: Blue screen - no signal - turns off [visio tv L42hdtv10a]

With out turning on the T.V., Push the [Input] button on the remote control. The TV should turn on and activate the input menu, just continue to push [Input] until it is set on TV (or HDMI, etc.). this should solve your problem.

Screen on LG goes to black right after turned on.


It looks as if the backlights are being switched off at start up, this will be due to a fault either with the inverter board or a fault with the screens backlights which would mean the screen needing replaced. Contact your repair centre to have an engineer give you an estimate on the cost of repair.

Black Rectangles on 42" Vizio HDTV LCD


Your DirecTV signal is probably too low. That would produce the small black rectangles (pixilation). Also, try replacing the cable you are using to get the signal from the DirecTV receiver.
