Question about LG 42LC2D 42 in. LCD HDTV

Open Question

Color distortion After the TV has been on for an hour or so the colors become distorted. A lot of purple/red " shimmers" on the screen and looks like a mirage. Eventually it goes away and normal color returns but it is unpredictable. Adjusting color on menu has not resolved the issue. All cables are connected.

    I am also facing the same problem after I shifted my TV from one place to another by scrolling the tv stand. The screen is divided into three colors pink, blue and green.

    I have a Samsung 42" that is 2 yrs. old. About 6 months ago started exhibiting the on and off color distortions - looks like cartoons. Initially you could tap on the top of the set and it would return to normal but that no longer works. Now the set is always distorted. I am trying to get some idea of what is wrong and just how much it might cost.

There are 4 bad Capacitors in this TV. LG just doesn't wnat to tell anybody......
I purchased four 2200uf @ 25v capacitor’s for $8 at a repair shop. I upgraded to 25v because these will run cooler. The tv came with 10v Samxon caps that seem to be problematic in all the units they were used in. Do not buy Samxon if you do this yourself.... I opened the set by taking off the plastic back panel and then by removing the second metal panel. There are three boards and a hard drive. The board on the far left just above where the plug goes in is the power supply board. There are five data cables and one red power cable attached to it that can be removed simply by unplugging them. The board is fastened to the unit with five small screws, one on each corner and one in the middle of the right side. If you look for three green capacitors grouped together around the middle of the board and slightly off to the right, you will probably see one that is bulging out at the top. This is most likely "C235", the main problem. The other three caps that need replacing are C202, C201 and C219. C219 is closer to the top part of the board.....
The process to replace is simple, believe it or not, and it could save you hundreds of dollars. 1, Go to RadioShack and buy a cheap soldering iron and a small roll of solder. 2, Buy four, 2200uf @ 25v capacitors, online or at an electronics store. 3, Plug the soldering iron in and let it heat up. 4, Locate C235 on the back side of the board and mark the negative terminal with a felt tip marker (you want to make sure that you put the negative terminal on the capacitor through the right hole, otherwise you will pop the cap. The negative terminal is clearly marker on all the capacitors). 5, With needle nose pliers, grip the cap and pull down while heating up the terminals. The cap will eventually come out. 6, Put the new cap in (you may need to heat the solder that is left on the board to clear the hole so it can push through). 6, When both terminals are through, bend them slightly so it stays in place. Take the solder and stretch out a few inches off the roll and while holding it in one hand, lightly touch the base of the terminal where it comes through the board, with the soldering iron and the solder at the same time. --- Try not to use too much solder.. you only need a tiny drop. This will solder the cap in place. 7, cut off the terminals close to the board with some snips and repeat this on the other three. 8, put the board back in, plug in the cables. Test the TV before putting the back panels on. It should work fine if all went well..... If you hear a pop than you reversed the terminals on a capacitor and that one will need to be redone correctly.... This might sound lengthy and potentially difficult but its worth a try. Otherwise you can pay someone to replace the entire board for BIG BUCKS with the same junk caps on it and have the same problem in a year or so. LG doesn’t want to take responsibility for this and I'm sure that it has cost a lot of people a lot of money for about $8 in parts........... This worked for me and it can work for anybody with the same problem.. Good Luck!

SOURCE: my vizio sv470m screen keeps distorting the images

Could be power board, could be main board, could be LCD controller and lastly - very unlikely yet possible - could be cables or rather cable connections.

It would help a lot if you post a screenshot or, better yet, a video of the distortion.

I somehow do not relate "distortion" and "blacking out".
Yet if I had to make a pick based on what you say and my experience I'd look at the main board first.

You should be able to get a replacement for under $100 at eBay and if you know what a screwdriver is you should be able to replace it yourself - a slow, but certainly not difficult process even if you do it for the first time.

Still I don't recommend spedning money before sharing more details and getting a more informed guidance as to where to look.

SOURCE: picture distorted goes red in color after 1 hour

Most likely the problem is bad capacitors on the video module of unit.If you take the back off you should see basically 3 circuit boards-Power Supply,Main Board,T-Con Board.Inspect the main board and the power Supply Boards for bad capacitors,in most cases the bad ones will usually have a bulge on the top of the capacitor,a normal cap will have a flat top,if you find any of the caps have a slight or big bulge,as if they were getting ready to explode,they need to be replaced with the same microfarads and voltage rating which is printed on the side of each cap.Replace them one at a time,you will need a soldering gun ,solder and solder wick to properly do the job.You can find all the tools you need at your local radio shack.The solder wick is used to extract the old solder so you can put a new cap in,the caps will have 2 legs.Also you must look at the cap and line up the negative side of the cap to the negative symbol on the board,there should also be a plus symbol where the cap goes in on the board.Good Luck and let me know if you need more information.

I want to buy a revlon limited edition nail color


If you are looking for the 2012 Revlon bright nail color line and it is the #240 Amethyst - Bright Purple Shimmer, then you can find it on eBay at this link:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=280945606340

If not, OPI has a great bright purple shimmer color and is an even better polish in my opinion if you can't find the one your are looking for. Here is a link to an eBay seller where you can see a great photo of it, but I think you can still find it in stores too.

The pisture is distorted on top left part of the tv and the color is off lots of purple


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

Wavy picture with blue and purple color.


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture
