SOURCE: Permanent horizontal line approx. 4" from top of screen

if this line is in the picture, that is possible burn in screen. if you have a black bar at the top or faint white lines that come down from top this is caused by defective filters in vertical circuit or bad vertical output. mch

SOURCE: The screen on my 4 yr old 42 inch LG plasma keeps

I believe that you are experiencing an intermittent problem with what's called your florescent lamp ballast. The best thing is that it can be repaired/fix. There should be a LG repair shop in your area. Cheaper to bring it in than have a service tech come to your residence.
Should be between $200 to $300 for a repair.

Horizontal Lines scrolling on screen


I had a similar issue with my Mitsubishi HD 1080. My power supply went out, I had it replaced and it works like new. However, just today I had AT&T U-Verse installed. When the cable guy was showing me the new HD channels all seemed good. This evening (about 5 hours after being installed) I started seeing these horizontal lines across my screen. The picture was still HD quality, but those annoying lines just wouldn't go away. Anyway, after reading a few blogs on-line suggesting interference or bad grounding, it hit me!!! The AT&T guy who installed my U-Verse (cable, internet and phone) had set the modem on top of my TV!!! It was just starring at me this whole time. So I removed the modem off the top of my TV and put it on a side table just to see what would happen and sure enough the lines were gone!!! You may not have the exact same problem, but it may be some type of interference (cell phone, modem, etc, either on top or around your TV that is causing the issue... Hope this helps. Thanks.

Green line down left side and geen snow


Horizontal or vertical bars on the screen could be from an ac line interference, adjacent magnetic field, bad input wire connections.....especially HDMI connector cables. A bad HDMI cable causes all kinds of unwanted picture interference. Check the conditon of all connection wires for proper fit and function. Keep in mind the method in which you connect your tv will result how the tv performs. As well this line problem could be a circuit issue too, requiring a technician to look at it.

Unfortunately there isn't any way to repair your tv as the magnet has distorted the tube that is in the tv and with CRT becoming obsolete the repair is likely to be very costly so probably your chaepest option is to buy a new tv .

Flickering crispy screen


maybe ur screen was put into a lot of magnetic interference. so check for any magnetic rays emitting devices like speaker adapters etc. a simple check would be to degauss( its in the screen properties). raja
