Any other components on board PSB ITC222 to be replaced?
After replacing the flyback transformer are there any other components on the board that should be replaced? Would like some input on this since this would be easier while the board is out instead of having something else go south after putting it back into the set. Thanks.
On another note, thers is a black wire attached to this board location BL501 shows connected to board PSDF ITC222 location BL670 but on the set itself was not connected just looped and set under a retainer. Is this correct not to be connected?

Cl031 is the sfaety retrace capacitor check DL030 an the HOT trans they are most likley blown as well. Usually if anything other than the Hot and DL030 are blown the entire deflection board will need replacement. Its also best to check all three of the CRT necks to be sure none are cracked and broken on the CRT necks . Unfortunately several designs of the deflection components had different parts although the deflection boards will usually interchnage bewteen the ITC222 chassis sets. The ITC222A will not interchange. www.tvrepairworld.com has replacement parts and boards and can also assist with part numbers that you require.
With that model its common for the Deflection board to be the problem when it doesnt power up. It can be the Power caps, Flyback transformer or several other items all located on the deflection board, so its usually best to replace the deflection board . You can get the deflection board PSB-260 from www.tvrepairworld.com which comes with installation instructions.
Unless you replaced the DL231 and the CL230 plus resoldered the flyback and vertical IC the fuse will continue to blow. The ITC222 and ITC222a convergence option missing repair kit from www.tvrepairworld.com contains those components and the CD with instructions. They also have circuit boards for your RCA.
Youre going to need the deflection board as the high pitched whine if it sounds like a short chirp each time the power indicator lights for the 3 times is caused by a surge taking out numerous components on the deflection board. You can get your board rebuilt through www.tvrepairworld.com which is fully guaranteed for 6 months. New replacement boards are not available anylonger for the ITC222
this sounds like the typical bad fly-back transformer that is also known as the high voltage transformer, n=-Not really a repair for a novice so unless you know all of the safety notices with this set please do not attempt this repair as why save 100 bucks for something that could seriously kill you!!!!!
thats called the flyback yes it easially replaced. the follwing link has replacement Flybacks and they provide free step by step instructions on how to do the repair. Your set should use the 259296 flyback if the tag on the rear says ITC222 chassis below the model number. Heres the link. http://servicemanuals.vstore.ca/
This is a convergence problem that is either poor solder connections at the convergence ICs or defective ICs. These are largel black ICs attached to a heatsink that should be marked STKxxx. If you can solder, you can fix this yourself. Try resoldering the pins on the ICs. If that fails to resolve the problem, replace the ICs. It is possible that there will be additional components that require replacement as well. Please keep us posted on your progress. Also, since there are high voltages present even with the set unplugged, please be careful inside the set.
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.
