RCA D52W20 Flyback Question

Hello, I was just wondering exactly how do you disconnect the wires going into the flyback to be able to remove the board to do soldering. Any help would be appreciated. I can tell that I need to replace the flyback but want to try resoldering the connections first.

    I checked the capacitors and they all look fine. I did find some capacitors that were blown on the board that connects to the RCA jacks on the back of the television. But on with my question, so the red cable comes out but they give a replacement. On the black cable, do I just have to pull that straight up to remove it from the original flyback?

Hello,

The wire comes out by pressing the two tabs in and pulling real hard, You will be happy to know that the replacement IHVT comes with a HV cable since 9 time out of 10 you end up damaging the IHVT cable connection. In any event before checking the IHVT I would suggest looking at CP150, CP120 and CP140 to see if they are puffy, since this is a common problem in this set.

I hope this helps,

Thank you,

    Hello Casey388,

    Technically the only cable you have to remove is the red cable. The black and white cables are fixed and have to be removed from the focus block and the CRT connector board.

    I hope this helps,

Check circuit board for bulging at the top capacitors. The board you are looking for is the one with the flyback transformer. This transformer is the one with a thick red wire going to the top of it. Replace all bulging capacitors. Capacitors are the ones that look like little cans. While you are there resolder the bottom solder points on the flyback transformer. This should work, because it worked for me.

Flyback Transformer


Flyback transformers rank about a 5 or 6 on dificult to repace.. depending on the model of tv that you are working with.. the rca itc222 can be difficult.. dependend on your soldering experences. To replace this one you have to pull the chassis tray up and out to get to the bottom... unsolder the pins ussally a vacum desoldering tool is required because it is important to remove all solder from the pins..then gently pry the clips that hold it on the board... this is where you can mess up unless the pins have be completly solder free you can crack the board... NOW the hard part... removing the wire from the flyback.. if the flyback is the type that the wire comes out. the wires will eather have a clip around the large wire or you will have to go to the other end of wire and pull it out from the splitter. eather way this wire is firmly in an will require gently but extremmly firm pulling to get out.

You will need some solder wick to remove the old solder. You need to heat up the old sloder with a solder iron and while its molten touch the solder wick to the solder and the wick will absorb the old solder. You will need to keep trimming the solder wick end so it will keep soaking up the old solder. Do that to all remaining pins on the flyback. The replacement flyback will not come with the high voltage wire attached so you will need to remove the wires from the flyback. This is accomplished by twisting the wire 90 degrees while exerting upward pressure. Instalation is the reverse of removal. Let me know if you need additional assistance.
