You need to replace 3 items FL231, DL231, CL230 then resolder the vertical IC and flyback conections. You can get the three components under the RCA parts category at this link.

Red blue green bowed looks like 3d no converg. menu.........


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • 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.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Do you have the convergence option in the customer setup menu? IF YOU DO NOT consult the tips and tricks section of this website for the article ' "The fl231 fuse problem" If you do then it will need some more trouble shooting

Red green and blue lines on screen


It is common for the 24V supply to fail when the convergence ICs fail. There should be fuses somewhere in the area that should be checked. I don't have the manual for this model, but verify that all of the wires and connectors are attached.

Keep us posted,

RCA R52WH74 Convergence Problem


Yes i replace that fluse fl231 all the time at the shop. at least two aweek. and the first few i replaced did the same thing. I would send it back to customer and i would get a call that the set had malfuctioned again and convergence gone. It was determined the reason this fuse blows is bad conections on the flyback transformer. The flyback is the big black component with the red wire coming out of the top. if you examine the connections on this component there will more than likely be a ring in the solder. this is caused by the manufacturing process known as LEAD-free solder. THis cause oscillations in that cuicit. like turning it of and on really fast. this is a very small fuse and cant stand up to this. so when you replace this fuse just simply RESolder these connections apply a little amount of solder to these connection. i am confident this will fix your problem.
