Question about RCA P52926 52" Rear Projection Television

Open Question

RCA P46813BL I have a RCA model P46813BL projection TV. The fuse blew out on it, and I replaced it. The TV works fine except for the colors seem to be out of alignment. The manual says the convergence can be realigned, but I can't seem to figure out how to do it. What do I do?

It is probably the convergence Power supply usually mounted above the main boards below. Most of them use a STK730-010 amp that is usually the problem, if not some used a little FET instead. It seems that PCB is available probably listed as a power supply rather than a convergence bd though

It can be done without Chipper check. Go to Parameter 80 and it can be done .First correct any green geometery. Then work from there. All this is covered on the ptk 195 cd

Hello I read ur answer to the Fl 231 fuse problem in rca projection tvs. I have...


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'

I have a RCA Home Theatre TV Model# P46813BL and we are having trouble congiguring the screen. We had a fuse blow, and have replaced it, but now our picture is off. We have used the TV remote to pull up...


If the color are separated then you need a new convergence board, or have it repair. If the controls are not working correctly then the processor could have some garbage in it, do to a small power surge, and you will need to leave the set unplug from the wall for 40Min. and it will reset back to normal.

Rca r52wh74 - no auto convergance


The model number of your TV probably falls under the ITC-222 chassis design. Do a search based on that criteria and it should point you in the right direction. If I remember right, you need to replace FL231 on the deflector board though. Good luck

Me again TV is driving me crazy....


Ok let see what we can do. These rca can be trouble. Im a technician and i see these alot. I guess that a good recomendation for these set LOL. First question. I take it you had the FL231 fuse problem... YOu replaced the fuse did you do the most important step. RESOLDER the flyback connections. i beleve that is step 7 in the instruction. this is the main reson this fuse blows. i have run into only one other case ...out of the hundreds of fuses i have replaced where the small signal cuircit board cause it to blow. but like i said very rare. i used to just put that fuse in and not resolder... it would come back to me within a day. LEt me know what happens

TV won't come on no noise at all is there a fuse in the back under the cover


That might be the problem, however what I would suggest is that you unplug the TV open the back look for a fuse remove the fuse (if you can, it might be soldered in) and then with an ohmmeter set to 1xR measure the resistance it should be 0 ohms. If it is not then that is the problem. If the meter reads 0 ohms then you will have to put the fuse back in and at this point I would suggest that you either replace the TV or take it to a repair shop.

I hope this helps

Thank you,

Try removing the Green CRt PC voard that is on the bottom of the green Picture tube which is the center one. Then replace the fuse and see if your set powers up if it does you need a new gree tube. Just be sure the crt board doesnt touch anything while you try it. then let me know what happened, if you need a tube they arent available new any longer but I have a source for good used picture tubes,

It is probably the convergence Power supply usually mounted above the main boards below. Most of them use a STK730-010 amp that is usually the problem, if not some used a little FET instead. It seems that PCB is available probably listed as a power supply rather than a convergence bd though
