Need Help With Blue curvy lines on LCD TV

Hi, I've been a long time reader but this is my first post here...

I have a 1 year old 32" LCD TV that just started doing the strangest thing. At random the screen gets filled with Blue curvy lines. the lines show up on white backgrounds and on every input I try: HDMI, component, RF, composite, S-video....

They come and go at random and sometimes don't show up for days. when they are there I have notice adjusting the contrast will make them better or worse, they never go away though..

Here is the best pic I can take:3303

Is there anything I can do/try?? or am I looking at a new TV?

Thanks for taking time to help...

Are you able to reproduce these lines with a dvd playing?

What brand and model TV do you own? Have you called the manufacturer about it?

YES! Actually They seem to always pop up when I am watching a dvd but After they show up they are on every input even with the DVD off...

I have a Westinghouse 32"
Model is a SK240.... I cant remember the rest
I have not called the manufacture because my warranty is up, I just figured it would be a waste of time.

I just took a notice to something else just now...
My Ps3 has a screen save feature where it dims the screen a bit. Well when the screen dims I can see the lines. They are not blue though, they're more like a "shadow" But they are in the same pattern that the blue ones are in so I assume these are the same lines that I am seeing, just some times they turn blue. Is this a calibration issue? or something terrible?

I'm not a HDTV expert but I learn quickly. Is there anything I can try to do? or should I take it to a repair shop?

I hate to be a bother but if anyone has any input I would be very thankful.

Can you give us the complete model number? I would still call tech support, because it certainly can't hurt.

SK-32H240S

Well the only reason I thought it would be a waste is because of past experience with Customer service. both sony and netgear have told me... " No warranty, No support" I couldn't even get advice from them! but I think i'll try Westinghouse If I can't figure this out, It hasn't happened in 3 days now.

Just a shot in the dark, but have you changed anything in the area where the set is located that is causing interference?

A whole lot actually but that was at Christmas, My issue just started the second week of Jan. I added a receiver a 360 and a fios cable box. I thought about them as being the cause but I unplugged all of them when the issue came about on Monday and the problem was still there. could there still be a issue? O and the Center channel speaker is under the TV but the manual says all the speakers are shielded and wouldn't the problem always be there if it was the speaker?

You would think. I wonder if you have a ground problem aka(ground loop). If you are able to move the TV to another room, plug it in and play a DVD and see if you have the same problem.

I think I might try that. Only problem is it hasn't happened the last two days.... Also my TV is on the wall and the closest component (PS3) is about 1 1/2 feet below it, that should be far enough away right? The only thing I can think of is that speaker. I read the owners manual again and found a small disclaimer that said "even though the speakers are shielded interference may still happen"

EDIT: I think I left something important out...
First; based on the pic does that look like interference or a LCD issue?
Second; If I mess with the settings, I.E. contrast & brightness, the lines move around the screen. Does that also sound like interference?

again thank you for your input and time.

Try unplugging the display overnight and see it something resets in the TV. If that doesn't work, it sounds like a video processing board in your TV has gone bad unfortunately.

I believe PFC5 may be right. If you still want to try plugging it in somewhere else, just take an extension cord and plug it into another outlet in another room and same goes for the dvd player.

Thanks for all the help, I have had the TV unplugged all day and will Plug it back in later tonight. I found out that my Wife leaves it on all Day long when I'm at work, even when she's out watching the TV in the living room :rolleyes: Great huh?

Also if it does end up being a video processing board how much does something like that run? I've been real happy with the TV, It has been almost as good as the 1080p tv in the living room. Also this is my gaming TV so I would hate to see it go.

The problem hasn't happened since Monday or Tuesday and if I take it to a repair shop should I wait till it's completely gone or take it now? I work in the auto repair field and I know if a car is not showing it's condition when it comes in I can't always find the problem. Does this apply to Tv's as well?

I also work in the auto field (automotive dealer). If it ends up needing repair, IMO it's not worth it verses the cost of a new 32" TV. Costco has a 37" Toshiba for $599. If a new set is not in your budget I would just continue to use your current one till it dies;)

well it's been quite some time now and the lines have not returned. Only thing is when watching standard channels through the cable box the picture looks blurry.... it could be the cable box but i'll have to test
it with the box in the living room...

anyways no blue lines for the last 2 or 3 weeks... maybe it was an interference issue? I did move some stuff around after the lines vanished the last time...
