My TV was in storage for about three months. When I put it in my apartment in October 2005, a problem had appeared: when the picture was intense -- for example, a bright solid color like white or orange -- the screen would "scroll." At first, it was annoying, but tolerable. Eventually, however, the picture started to scroll all the time. This happens both on Composite and TV Tuner input. However, it is completely fine on Component input. I'm not able to test S-Video because it looks like one of the pin holes on the input connector was damaged at some point.
At first, I thought the problem might have something to do with NTSC decoding, but I realized that the component inputs are NTSC encoded as well, so that's out. I've worked as a computer technician, so I'm fully capable of making any repairs to this set that are needed, but I don't have experience with TVs, so I don't know how to troubleshoot.
I've thought about de-soldering the S-Video connector, in case that whatever damage is there is affecting the picture. However, since it's only one pin, I can't fathom how any damage would cause a short or anything that would disrupt the picture.
Since this was a progressive-decay problem -- i.e. it started with the bright picture and then eventually started happening all the time -- I'm a little stumped as far as troubleshooting goes. Perhaps a capacitor slowly died on me? I don't see anything exploded or badly soldered inside. Any ideas?

Re: Picture scrolls on all inputs except Componenet
It certainly sounds like a defective capacitor. Was the storage area hot? Electrolytics can dry out and change value over time or flat out short out. They don't cost that much and it sounds like you know what you're doing around TVs. I would start in the vertical circuit and replace all electrolytics. Also look closely at all connections with magnification and solder anything which looks suspicious. If you have a scope and know how to use it a check of various waveforms should identify the culprit. Good luck and remember safety.

Whatever video components you have, they should be, depending on inputs on TV, should be run to TV first. Recievers do have pass through ports but, are not the best way to achieve picture and sound. HDMI cables are great but you r reciever may not be able to transfer the video. What I suggest is taht you run your componenets, cable/sat box, DVD, etc. via HDMI, componenet, etc., to TV input, then, run audio out from TV, via(best) digital optical. You can use TV's menu to choose what you watch while, you only have the one input to reciever. Scan your recievers menu to make sure you have selected the proper mode(TV, Aux, Vid2, etc.).. If you run your video unit to TV with component cables, you will have to get your sound through separate cable(s). Component cables have graet video, but do not carry the sound.
This is a manual that should help you, it may even be your model but, it shows hook ups and has a page about the Simplink: http://www.lg.com/us/support/product/support-product-profile.jsp?customerModelCode=37LH30&matchedModelCode=1000009240&searchEngineModelCode=37LH30&initialTab=documents&targetPage=support-product-profile# Scroll down to manual, ckick on the one you want, and open. Typically, you would want to hook all video related units directly to TV, via HDMi, Component, RCA, etc., with the componenet video, you have to also have an audio cable, because the componenet does not carry sound. In other words, you want to hook things like, cable/sat box, DVR, etc., directly to TV then, use your digital optical out from tv to digital optical in on your home theater. You use your TV's menu to select what you are watching and you only have to use the one input setting on receiver to listen to all. If you try to route you units through the home theater system first, you may not get the best results and you may expierience lags between the video and audio.
I have never herd of a red and blue combo but, The three, red, blue, and green are "component" cables. Hopefully your DVD player has a red, blue, adn green component out, not to be confused with red composite out. Composite cables are yellow, red and white, and, your tv has componenet in. The component cable will give you the best video quality. When installing make sure they are inserted all the way but twisting and wiggling or you will have a bluish, grenish, etc. picture. The composite cables give you the video only, so you will have to provide the audio. Audio can be achived using composite red and white or digital optical.If you second monster cable is red and white you can probably use those To go from "audio" red and white out on DVD to audio in red and white on tv. You must use the same audio input that corresponds to you video input.
