Not likely. I would attempt to get a deflection board to fix the problem.

Tip

I replaced the fuse and the tv worked for nearly 20 minutes then it blew again....


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'

Okay let me know what you think


the flyback transformer is the large black component simalar looking to a disrtibitor of a car it has a large red wire coming out of top and a black wire. On the bottom of the board it has about 10 pins arranged in a circle. this is flyback is located adjacent to the fuse.

If all 3 colors are mis-aligned, you may have solder connections that blew a fuse. There are three fuses next to the flyback transformer, one usually blows causing this issue. Resolder the flyback solder connections and replace the fuse to fix.

yes the flyback is inside the TV, and yes I can post a link where you can get a new replacement for around 50 dollars and it comes with free on line tech support so you can do the job yourself. Its a job that only requires basic soldering skills. If you would like the link let me know

RCA P46921. Just changed flyback.


if nothing has been tampered with ie. focus controls, lens focus, I would check to make sure the high voltage lead is seated correctly.

Congrats on changing the fly and getting it to come on. If it is a sony as it looks at the top of this page (accurate model?) need only to adjust focus and/or the horizontal static control. can't tell you where the horizontal static control is exactly but there are large wire associated. If not a sony then adjust the focus on the flyback.....top control bottom control is screen or for brighter picture.

TV repairman blew fuses??


yes maybe ...but he made problems alot worse bypassing your fuse, the fuse is there to blow if you have a short and not harm other components. my guess is that he damaged your power supply and then fixing that youll still have the orginal problem. I think I was the only tech in Houston that could troubleshoot. Sad, but very few good tv men or big screen. we trained are outside guys not to touch much but do slight adjustments and bring it into shop if you dont have a clue and they make some story up to the customer. good luck
