change the convergence fuse located next to the flyback its red and shaped like a rectangle ref fl321 number . part number is 259213 400ma 125v you can order at ebay or from newark com for 51 cent there part number is 67K2174. its the same fuse.
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'
The FL231 is available along with the DL231 and CL230 which should be replaced all together. www.tvrepairworld.com has the ITC222 and ITC222A convergence option missing repair kit it conntains the parts and instructions on CD.
there are 3 fuses in a row next to the flyback
transformer.solder all the pins on the flyback
and replace the middle fuse.check the other 2
fuses.this is very common with RCA.
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
ok first question i have for you is.....in your setup options in the main menu do you have a convergence option... if you dont it is probaly a very specail fuse that lets the set know it is a projection tv with 3 tubes ...fl231... if you can get this fuse rca part #259213 and you can solder. i can tell you how to fix this and it will cost u 5 bucks and no more than an hour
you need to replace chemical type fuse marked FL231 part number 259213, it`s located next to the flyback transformer, theres 3 of them there but 231 is the only one I`ve seen cause your problem, replace it and you`ll be all set.Happy Holidays !
