Question about RCA HD52W59 HDTV Projection Television

2 Answers

Fl231 Hi - I have noticed in all of your posts you warn about the power for the people who are going to try this fix. Is that warning just so you dont get too close to the flyback? I assume I need to just pop that old fuse out and solder the new one in. I don't have to worry about getting fried just by doing that, do I? I will unplug from the wall. Thanks!

    Thanks for that info. I went up to Radio Shack and showed them a picture of the fuse I found online and they said they didn't have any fuses that looked like that. Should I have asked for a resistor, or would it only be called a fuse? Also...do I have to remove the old solder, or can ~I! just take the one off and put the new one on?



    Thanks!

If you got a steady hand you fine. just try not to short anything. the flyback is not generating voltage unless running. the mains input board or the one with the plug in it and the main capacitor is the one that holds the charge. you should be ok i just warn everyone. and the charge usally goes away after about 30 min to hour. replacing that little square fuse next to flyback should be any trouble.

Does the rca 52950 have the fl231 fuse? If so where is it located? If not which fuse controls the convergence. I fixed my newer model tv with the fl231 fuse but I dont see it in this tv.


no the fl231 fuse is only for model itc222 rca's . these older set unfortunately do not have that fuse convergence is contolled by a sepreated cuircit board. also these set have no stk ics that are common for most set that control convergence. it uses a series off transistors.

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'

NO POWER rca hdtv R52WH74YX61


if the fuse you took out at first was fried black as cool, how do you know it was .6a
now the fl231 as I told you before is close to the flyback transformer
Go to google search -type in flyback transformer --enter
scroll down to get video results for flyback
click on the picture
now you will see what a flyback looks like
you should not try to fix tv if you have no idea of tv repair.it is very cmplicated and fatal .there is serious high voltage in tv sets

Fl231 replacement


ok first lets determine if the fuse is the poblem. do you have convergence option in the setup in customer menu. if you do then it will not be the fuse. if you have that option go into blue and red convergence. when you arrow over left or right up and down do the cross hairs move if they dont then it will be the power board(convergence)

Bad picture


3d multicolor pitcture. is and indication of what is known as a convergence problem. First question. when you go into customer setup menu do you have the convergence option. if you do not then it is a common problem known as the fl231. This is a special type fuse that tells the tv that it is a three tube projection and not a one tube type tv. If you do have the option go into it and got to both blue and red convergence see if they move at all using the remote. if they do not move then you might have a convergence power board problem. if they do it might be a convegence amp or just s setup issue. i HOPE ITS just the fl231 there like 5 dollars and easy to replace if you know how to solder i fix this problem weekly on these sets at the shop. WARNING THESE SET GENERATE LEATHAL VOLTAGES EVEN UNPLUG THEY HOLD A CHARGE. if you are not experence with electronics be carefull. if you have any question let me know if i can help

Hi ,here is some of the tips found on www.repairworld.com no convergence- replace fuse FL231 near flyback or in front of flyback also solder flyback pins alot of these sets have poor connections,they are having alot of trouble from ribbons that connect from bottom tuner broad going to convergence broad also connectors that ribbons plug into so far there is more infor on the HD52w59 .The next set i get in my shop the first thing is to solder power supply broad,then see what happens so far the 2 sets i have now i havent been able to fix,but im not quiting untill i fix them or throw them back to customers.
