The Fl231 PROBLEM(CONVERGENCE NOT IN CUSTOMER MENU) ITC22 chasis


FL231. FUSE.... The RCA ITC222 chasis has a common problem. and it not all that difficult to repair. Does your rca projection tv have read blue and green shadows? Does it have bowing in affect on the top and bottom of picture? when you turn it on does some thin red green and blue line bow in from the top then go away. The main question to determine if you have the fl231 fuse problem is if you go into customer menu then setup do you have the "CONVERGENCE' option. If you do not. then i suspect you have this problem. In the manufactering of these sets Lead free solder is used. now there is great debate over the use of lead free. connection tend to be more brittle. cracks develop around the solder connections of the high voltage flyback transformer. this very small crack set up oscillations in the cuicit with a 400 milliamp fuse. THis fuse cant take it. When this fuse blows the processor then does not know its a projection tv with three projection tubes. it thinks its a crt tube tv. and crt tube tv dont need "convergence" so it removes the convergence from the set.

TO REPAIR... 1. Warning. this set can generate leathal dangerous voltages even unplug do not attempt if you have no experence with electronics.
2. Remove the back. there a number of torx 20 screws.
3. what you will see is a number of circit boards There will be one on the right and one on the left. the one on the right is the small signal board. the one on the left is called the power deflection board. it has a large black part with a big red or black wire coming from the top, this is the flyback.Next to the flyback on the right of it there will be three small rectangular componets tan or brown in color. these are fuses. the one in the middle is the fl231 fuse.
4. getting to this fuse can be difficult. these two cuicit boards sit on a tray that is removable. to remove this tray it is pulled out and up. BUt watch the wires.loosen the wire tyes.
5 when you get the tray up the bottom side of the board can be accessed
you will now have to unsolder that fuse. one side of this fuse is under a plastic part of the tray. i have found the easest way is to cut away the plastic to get to it. if you dont want to do this you will have to remove the board. only remove half of the plastic brace
6. REPLACE FUSE RCA PART 259213
7 RESOLDER FLYBACK CONNECTIONS simply heat up and add a little solder
8 reassemble set. make sure you examine the set for loose connections.
9 and remember "BE Careful'

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.

f0900cb.jpg
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.

Rca hd52w59 3d screen colors are seroperated no convergence


i have found the reason for the fl231 fuse blowing is faulty solder connections on the flyback transformer is the main cause. I have came across only one bad signal board that cause this but this was very very rare 1 in 1000. This is a very specific fuse, .400 and it is recomended only to replace with exacte one. consult the fl231 problem in the tips and tricks section.

RCA HDTV LOOKS LIKE THE PICTURES IN 3- D PLEASE HELP


There are 3 small fuses that will blow if the solder connections on the flyback transformer crack. If you open the tv, unplugged of course, you will see the flyback on the left most board.. the big thing with the red wire coming out of it. the 3 fuses are small orange squares just to the right of it.. two are 400mA and one is 1.25mA i believe.. anyways youll need a multimeter to check them and see which is blown.. solder the connections on the bottom of the flyback and replace appropriate fuse to fix. If only one color is off place, try going into the convergence adjusments in the menu to resolve without repair (might get lucky).. if its all 3 colors bowed on all sides, this fuse/soldering should fix it right up. A repair center will charge maybe $200-250 to do the job

fl231 is the convergence fuse, and is soldered to the board in proximity of the convergence ICS, on RCA rear projection TVs.


If
fl231 has blown, TV usually does not turn on at al, if you get bowed picture, that means that the convergence ICs must be replaced.

The fuse is on the same board where you find convergence ICs, if the fuse had blown, or the pico fuses at the base of the STK convergence ics had blown, the STKs must be replaced.
There is need of purchasing the service manual to do the job.

The repair shuld be done by a technician.

This is the convergence IC, model may vary:

Convergence problem?


i would guess that fuse fl231 a .4 amp special fuse is blown. this is common thing.if you can find the fuse it is rather simple and easy to fix. rca part 259213. a snall rectagular tan fuse. there are 3 next to the big black flyback transformer. it is the middle one. after that is replaced then you have to resolder the connections on the flyback generally that is what cause it. this repair is ussally on the r52wh74s i have never seen this on d52w20's but i guess it could happen

RCA R52WH77 convergence missing from menu


THis is very common on these sets. there is a special fuse thats cause this.. kinda hard to get rca part number 259213.. .4 amp. the reason this blows is there is bad solder connections on the flyback. so when you replace this fuse you have to resolder these connections. so if you know how to solder and can find this special fuse. it is a fast and easy repair
