Ur tv have a problems known as a convergence problems it dead.Tv have colors lines like R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?Tv have a dead convergence board,board must require replacing 2 STK convergence ICS and some or all of it resistors too.To fixed the convergence board to solved the tv picture convergence problems.The shop,will coat u like $300-350 for parts and labors.
Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include....
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.
5 times blinks is error code for No Good White Balance and you said that picture is very green. As you know TV is approx 7 years old so it needs RGB gain adjustments. If you are TV tech person or know about TV repair, let me know to guide you further. Or contact local TV repair shop to fix it.
ok you have convegence problem. i suggest you read "fl231 problems under tips in tricks of my profile. this could be a simple easy inexpensive repair. i believe you can get to it under my profile. if that dont help then let me know i will help you further
You may need to perform convergence on the unit. This is something that needs to be done periodically and especially if you have recently moved the unit. You can normally find the convergence option in your menu system.
I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.
The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).
Most projection TVs have an option to refocus. For example, my Sony rear projection TV has a button on the front for focusing the lamps. Try finding this button or option in the menus with your remote.
Projection TVs actually use three lamps, one red, one green and one blue. These need to line up exactly in order to form a good picture, and when they come out of focus, you see the edges which sometimes has the effect of a 3D image when you aren't wearing 3D glasses.
Hope this helps!
Have you taken another set an hooked up the cable or sat. to the other tv from this tv? Try that first thing. Next try the video input like with a dvd or vcr. No lines ?? Then sounds like the tuner could be going bad in this set. if you still have lines then its a problem in the video or horizontal section in the tv set. There are no user serviceable parts inside this set so its anot advised to gointo this set to try to fix it. You can get a serious shock or cause more problems with the set. I know you said it is about 5 or so years old. Its at the point of do you wanna invest in this set?? If you really like the way it works then a tuner shouldnt (if thats the problem) run more then 2 to 3 hundred bucks with the labor. Good Luck
