The solder joints are loose on the flyback transformer and that is what is most likely causing the fuse to keep blowing. Resolder the connections and replace the fuse and you should be good to go.

Sorry to hear about your problems with the RSA 52"
This unit has had its share of technical problems in the past.

1st. I have know way of knowing which fuse you have replaced, as their are several which handle limits for different section of the unit.
If you have replaced the main fuse in the power supply and you have not found why the fuse has blown, you are wasting your time in the attempt of repairs.
Example, you have changed the fuse in the power supply.
The problem may be in the audio circuit, which is in series with this supply.
If the audio circuit has a bad cap and it draws a over-limit current, or if the problem is in the vertical high voltage circuit, changing the Fuse will not repair the problem, in-fact will more than likely make it harder to diagnose later down the line.
Hope this information has been of some help.
Thanks,

Resolder the flyback pins as thats what causes the FL231 fuse to blow. Soldering the flyback should solve the issue you may need to replace the fl231 again

Tip

This is great step by step, and it makes sense, but the problem is that I have a...


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'

Auto convergence disappeared from the menu on my 52" RCA TV, Model #R52WH73. This TV is just 1 week out of warranty and the timing is impeccable.


Replace FL231 that will bring back your convergence option in the menu. If the Fuse blows again, you will need the Convergence power supply board. If you need more assistance please let me know
