The Fl231 PROBLEM(CONVERGENCE NOT IN CUSTOMER MENU) ITC22 chasis

Hey Will I talked to you on the phone and you referred me to the web site. I replaced the Fl231 fuse and did not understand what I needed to do to resoder the flyback connections. When I went to turn it on I could hear it recieve power, but the picture never came on. The power light would stay on for a few seconds shuts off turn back on then shut off for good.

no the board that has the FL231 on is the ITC222 deflection board. The other board is above the chassis in a seperate frame that runs across the set the convergence power supply is the board on the left above the board where the fL231 is. Yes the ITC222 and ITC222A are the same chassis. As for the service manual that site should have the service manual under the thomson category as the ITC 222 chassis is actually a thomson chassis made for RCA.

in customer menu under setup do you have the convergence option. If you do not it probally be that fuse. this fuse is located on the main defection to the right of what know as flyback.. which is a large black component with two large red wires coming from it.

SOURCE: how do I replace fl231 fuse, and repair flyback transormer

I'm sorry, but you have no idea what you're doing. STOP!!!!! What makes you think the fly is bad? A bad fly will not let the set come on at all. If it was me, I'd be thinking the convergance circuit. That's why you have the 3D picture. If you hell bent on your diagnostic, The flyback is the most recognizable part inside a television. It's big, It's plastic and it has a big red spark-plug looking wire coming out the top. You unsolder it from the bottom. RadioShack has a desoldering iron with a red bulb that works great. Also some solder wick. Unsolder the pins and remove. Then replace and resolder. Same thing with the fuse. The fuses are all marked on the circuit board itself. Any part on the board must be removed by unsoldering. You need to trouble shoot in a better way than you are or you'll be spending alot of money you don't need to. Also, if you don't know what your doing, you can get yourself into trouble real fast and make the set unrepairable. Most shops won't work on sets that the customer tried to fix themself. You got me VERY worried. You are the guys I worry about giving information too and wind up killing themself. Please....get some help with that thing. I just don't want you getting hurt or destroying your T.V. It's an easy fix right now, but you have to know what you're doing.

These sets do not have convergence ICs it has convergence board most common problem with them is if you go to menu then setup and do not see convergence on menu then you have a open fuse FL231 they are located on right side of FBT flyback transfomer thier is 3 in a roll small brown rectrangler looking caps but are FUSEs it will be the one in the middle.

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'

I have an RCA HD52w59 with a convergence problem. I've been told different things on this site. First I was told to change FL231, CL230, and DL231. I've also been told to replace both IC's (STK392-110)...


Your set doesnt have STK ICs. If the convergence adjustment option has disappeared from the on screen menu, then replace FL231, DL231 and CL230 If the adjustment option hasnt disappeared from the menu then you need to check the resistors on the convergence power supply board some of those will be open. The actual convergence Board will usually not develope problems just the Convergence power supply if the convergence adjustment option is still in the on screen menu.

My 52' rca tv started showing red,blue, and green double picture and i cannot find the converge in the menu what can i do ..


if this is a rca itc222 chasis then you might have the fl231 problem. check out the ariticle under the tips and tricks section under my profile. the convergence menu is under setup in the convergence menu. if it missing then it may be the fl231. depending on what the model is.

RCA P52960 Problem (bowed picture)


Normally this is either bad connections on the convergence ICs or defective ICs. If you can solder, you should be able to fix this. First locate the convergence ICs: large black ICs attached to a heat sink that shouldbe marked STKxxx. Try resoldering the pins on these ICs first. If that fails, replace the ICs.

Keep me posted.

RCA 52inch Model R52WH77 HDTV


may i suggest reading the ariticle the fl231 problem in my tips and tricks section of my profile. YOu MAY have a 5 dollars 30 minuter fix. Determine if you have the convergence option under the setup option of the customer menu. if you dont then congratulations you have a simple fix. i you do have the convergence option and the autoconvergence then you might have other problems. and will have to troubleshoot further. If so ill talk you through some more. THIS set has NO stk convergence ics. my feeling is the fl231 which i see alot on this perticlar model at the shop

Fl231 fuse compatibility


yes, thats the replacement fuse for your set. However unless you have replaced the convergence power supply also chances are the fuse will blow again, as the power supply shorting is what causes the convergence to get out of alignment and it will then blow FL231 thereby removing the convergence option from the menu.

I have serial number hd52w59


the fl231 fuse problem will apply to any itc222 chasis set. The hd52w20 is an itc22 chasis.. although i have not seen it in that set if you do not have the convergence option in setup. that is my first choice in possible problems. a simple ohm chech of that fuse can determine if it open. Warning this television can generate potetial leathal voltages care should be taken when working with set with back off.
