Why does my sony tv and a DVD connected to tv, when turned on, shuts off right away?

You can use the RCA style jacks, Yellow for video White for left and red for right audio OUT . Connect the TV end the same way. Note the source input number on the connectors of the TV. Turn both the TV and the Sony on. On the TV, select the input number the cables are connected to and you will see the Sony . If there are no unused places on the TV to connect to then take off the antenna/ cable wire off the TV and put it on the ANT IN connector of the Sony. Obtain a jumper cable wire long enough to reach the TV from the Sony and select either channel 3 or 4 whichever channel is not used in your area on the back of the Sony. Now turn both on and select TV as the source and put it on channel 3 or 4. Now turn off the Sony and change the channel on the TV to any other one in your area. If there is no picture, then the Sony will have to be on while watching TV.

could be alot of things but it comes on by hitting it makes me think either a bad relay or solder connection on the pcb board

DUI is actually trying to display DVI on the box (the LED won't display the V and makes it a U). You typically see this error when your connected to your TV through an HDMI cable and the handshake for HDPC is lost. The box thinks your TV doesn't support it and wants you to change your connection. The error should go away once it finds that handshake. If you were using a different input on your TV, maybe a composite or something for a DVD, and then switch back it can get lost. If it doesn't clear right away try shutting everything off and turning it back on by turning on the TV first and then the box.

1. Connect cable to cable HD DVR box, connect video out of cable box to Sony receiver TV video in, connect audio L and R out of cable box to Sony receiver TV audio in and connect TV out of receiver to video in of Panasonic projector 2. Connect Audio and Video out of DVD player respectively to DVD in of receiver. Good Luck :)

connect ur rca cables from the main left/right sockets of dvd to into audio input in tv

Its correct, Sony is no more selling plasma and I think many companies has already shut plasma production and CRT TV as well.
All TV manufacturers are busy in LCD TVs.

YOU MAY HAVE A BAD IC 2504 OR M BOARD EST $250.00-450.00

Try scrolling thru the TV's video inputs. When you get the right one, the circuit will automatically recognize it and play provided it's connected properly

does the tv realy shut off or does the pic go away sounds like bad tube
