Re: tv powers up have sound no picture erea 40 lcd
DO NOT under any circumstances hit the neck of the picture tube. While it is possible that the tube is bad, that is not the most likely cause of your problem. Please post the make and model and I'll provide additional details.

It needs repair. If the line is vertical, then something is damaged on its horizontal circuit section on the mainboard. If the line is horizontal, the vertical circuit section is damaged. have it repaired to a qualified service center or person! avoid switching it to avoid further damage on other parts!
Ok try turning the tv of for 40 minutes by the power point and back on. that
way it will reset picture - and should go back to normal please let
me now how this goes ((By a rating
Make sure you un plugged it by the power point for the 40 minutes
also make sure there is no speakers or anything magnetic within 60cm's
of the tv this can also cause the picture to have strange colors in the
screen - if that happens simple do the above
We had a TV repairman look at our 3 year old (Oct 2004) Panasonic CT-32HXC14J FLAT SCREEN TV. It suddenly stopped working and appeared to have no power getting to it. It was a high voltage supply or transformer that was bad and has to be replaced - estimated cost is around $400. In a year we will also need to spend around $125 for a digital converter box. We went for the repair since that is still cheaper than a $1,000 plus equivalent size LCD or plasma.
Our old tube tv was still working after 15+ years. They aren't making them like they used to. Way to go Panasonic.
Sounds like you have lost video somewhere in the video circuits. Possibly the picture tube could have gone bad or lost filiament voltage.
You can check to see if you have high voltage by holding your bare arm close to the screen. The hairs will stand up if you have high voltage. Absence of high voltage will also cause a black screen,but the sound might not work either since on some sets the power for the sound is supplied from the same circuit as
the high voltage.
