Question about LG M4200C 42 in. HDTV-Ready LCD Television

Open Question

Tiny horizontal lines blurring picture - no known trauma, but highly irritating.

Our TV is less than 1.5 years old. Recently, there are horizontal lines that make the picture blurry. This is especially noticable when there are words on-screen. These lines are present with the satellite feed, with DVDs and VCR tapes. Always.

SOURCE: purple line down middle of screen

I could do with a digital photo to be sure, however it sounds like the LCD panel itself has failed.

Are you under warranty? Chances are real good that you need the signal board....the one with the rca jacks and rf connectors. This may be pricey $$$$$ but will surely repair the problem.

Poor picture quality on alba LCD TV after recent digital switchover.

Digital TV uses less airspace than analogue TV, so after the digital switchover there'll also be more room for services such as high-speed mobile broadband and high-definition television (HD TV).

Horizontal lines shadowed / blured picture after 20-30 minutes

There are some semiconductors or capacitors that are leaky. Might need thorough check up inside the TV.

The sound is great, but the picture has gone to gray with horizontal white lines across the screen. It is 20 years old, and probably not worth fixing, but i will ask anyway, just in case it is a simple...

Hello Sat, hi, its a failure of the horizontal output transistor responsible for high voltage. This transistor is needed to be replaced. you need a TV tech guy to have this fixed. have it checked first, the trouble is common to CRT type TV really easy to fix. for a tech guy.

I've had my Toshiba 46RV530U less than 2 years,

Diana, did you ever find a solution? My Toshiba (same model) is about 2 years old and it started getting these 4 horizontal lines spaced pretty far apart and a double image at bottom. When I lightly tap the top of the TV, they went away. But now that is not working. Please let me know. Thanks.

My TV is less than a year old. It has white

Do these lines disappear after the set warms up a little? If they don't then you most likely have bad buffer boards(X buffer or Y buffer). Sometimes it is also caused by a bad panel. Since your tv is less than 1 year old and is still under the 1year manufacturer warranty I strongly suggest that you contact the manufacturer for repairs.

12 little horizontal lines in Sony Bravia KDL-52W4100

It's the panel. Mine took a sharp force trauma when it fell only 1 foot onto something very pointy (a cellular external antenna) and it looks like it got shot by a bb gun. And it has lines kind like what you are describing.

You can't fix an LCD tv with this kind of problem. You just can't. The LCD panel cost more than a new TV. I know I asked the local Sony Shop to just order me the LCD panel. It was over $900 on a $600 retail TV. I was going to replace it myself ... I fix laptops ... but not at that price. So far I'm just using it as it is, until I want to, and have the $$$ to buy another one.

Good luck on yours.

(a laptop lcd panel repair costed over $300 by the way on a $600 laptop with a few years age on it. I did it mainly as a learning experience. But never again.)
