Picture gets fuzzy or goes black with slight vibration.
Any vibration near the TV (like when kids are playing in living room) causes picture to get fuzzy or picture will go completely go black and immediately come back on. Is this a normal LCD tv problem? I purchases it at Circuit City with extended warranty. TV is a LG 42" LCD HDTV
Re: Picture gets fuzzy or goes black with slight...
It sounds like a loose connection with your signal but if the connection is tight i have seen loose connectors on the small signal board itself which may be resolveable by resoldering connector on signal board which would be far less expensive than replacing signal board itself

The fuzziness is radio noise from space. No I am not kidding. It's from the background radio spectrum of the universe's creation and it is uniform and OMNI-directional, so it will always appear as snowy noise that is fuzzy in appearance. You can't remove this noise unless you connect a signal from a TV station or cable that is much stronger in strength than this noise. If you mean that a TV signal comes in and appear fuzzy, it is because this TV signal is very weak and you need a better antenna to increase the signal gain. Hope this helps.
Sounds like a blown capacitor on your board to me. Its a common problem in Samsung TV's and is typically an easy fix, but I think in the LG's its a bit more expense and not as easy as swapping out a Capacitor. I think the main board may have to be replaced there. What actually happens is the capacitor bursts at the top and oozes liquid that solidifies, its caused when the capacitor that is used is underrated for the application (basically some engineer's solution to making us have to buy a new tv in 3-4 years, a slightly underrated capacitor will have a shelf life of use, kind of like a timer, they all do it belive me) eventually the set will not rendure any picture at all and the board will have to be replaced.
Not really a solution, sorry, but I've got the very same problem. I haven't noticed the time before tv faults, but nontheless, it greenscreens or like in your case, redscreens as well. I've been told to open the back, which I did to check the status of the capicitors, which I've done. But, the capacitors "seem" fine. No bulging or popped tops. So, I'm at a stand still...not sure what to do at this point. If someone gives you solution, I sure would appreciate your forwarding it on to me. Thanks. Robert
Yes you will get a better picture quality out of a cable box if you get an HD cable box. The reason you are getting the diminished picture is due to the signal you are feeding the TV is an analog signal. The newer HD TV's are made for digital TV and this older technology shows all its flaws on this type of TV.
When you get the new box understand that the same channels you are getting plugged directly into the tv are still going to have some grainy look to them but the good thing is that a lot of them are starting to be rebroadcast on HD channels and that is where your new toy will truly shine.
yes,remove the back of the tv,on the power board you will see the problem.replace those capacitors on the power board.this will allow the set to work.the black bars may still be there.this is an indication of a bad panel.
I had issues when I set an SD override for the box, it would sometimes display as bad input when switching to HD content(as well as display all menus in SD even with HD mode in settings.) Turning that off in settings (also turned off "modes" which has no description) stopped it and gave me guide/menus in HD.
You should check your home wiring and grounding. Also be aware of anything that has recently been turned on when this happens. Anyone using a microvwave, cell phone, or other appliance that might be causing the interference.
Well, I can tell you it shouldnt have anything to do with your not having an HD box. The TV does not require a HD signal to give you a quality picture. The HD box only gives you the enhanced HD signal, but should work as any regular TV without it. How do you have it connected?
