Horizontal convergence line rolling up the screen

I have an RCA HD56W66 projection TV, it had a convergence issue and I replaced the FL231 fuse and resoldered the flyback. Now it looks good but has a 'rolling' convergence problem going up the screen. Any ideas? A cap maybe?

It sounds like an Intergrated Circuit (IC) has fried. Even on a good day, this is not something you can attack at home. As a tech (and as an owner of that model samsung), I'd need a map & tools to know what's going on. Your best bet in this situation and let them recommend an authorized service center in your area. but this is a rather serious problem...

thank u
rate me!!

The convergence box keeps going out.


this 3d effect is due to what is known as convergence.i work daily on these set in the shop. (thats a good testomony for these LOL) but the first question i ask is 1 in the customer setup do you have convergence option.. Next question is the picture bow tie looking and 3d. if you are missing the convergence option chances are it is the fl231 fuse. then you need to read the fl231 fuse under tips and tricks section of this website. Convegence is controled by three cuicit boards. if any of these need to be replace a technician may need to set or adjust the convergence back to faactory specs

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as 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.
Here are some pics of convergence problems.

For more more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

Common Problem #2) CRT Fluid is Cloudy

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.

Picture of a set that needs the fluid changed.
