TV has blue vertical lines and no picture

If you get a clear picture using your DVD player, then the problem may not be the TV, but rather with the satellite decoder, or the wiring from the source to the decoder.

Good day!

that problem is on the cable please try to play dvd or recorded tv shows.
if you play dvd or recorded shows and picture is normal
try to check the connection of your cable and try to touch the connector and move it gently then see the picture of your TV if there's changes

thank you

I've had the same problem. (black vertical lines) They will appear then go away. I have a 42EDT41 42in. Now my screen has gone completely Black.

You have bad capacitors in the vertical deflection. And you will have to resolder the vertical IC as well. Replace the caps in the area of the vertical IC. Find a TV tech or hobbiest to do this!

vertical ic fult or vertical section supplys missing

the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

Here is a picture of my TV problem, the green horizontal line is from the camera flash. thanks for the help.

My Lcd monitor has blue line? How can I solve this problem?

IF THE LINE IS ABOUT 1INCH WIDE THE CHANCES ARE IT WILLBE YOUR PLASMA DISPLY THAT HAS GONE . WOULD BR CHEAPER TO BUY A NEW UNIT . HOWEVER TRY RINGING HITACHI EXPLAIN THE FAULT COMPLAIN THAT IT SHOULD OF LASTED LONGER THAN THE WARANTY AND SEE WHAT THEY WILL DO ABOUT IT
