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?

i hope your tv is more than 4years old ....... in all CRT TV's or CRT monitors after 4years a component called flyback transformer (see picture ) becomes weak - its work is to supply voltage to tube............. then following are the signs ... (1) in some TV's only front LED's blinks - no picture no sound.... (2) in some TV's picture comes slowly after few seconds or after few mins or after few hours......... (3) in some TV's suddenly picture & sound goes temporarly & after some time again it appears ...... etc in case of (2) & (3) only flyback transformer needs to be replaced .....100% GUARANTEE again TV works normallyBUT in case of (1)... --------------- YOUR CASE (a) either only flyback transformer gets deffective or (b) flyback transformer & another component called transister ( will be near flyback transformer & its back portion is attached to aluminium metal ) gets defective or (c) along with flyback & transistor -- 3 or 4 more components (resistors, diodes, some times ICs ) gets deffective so replacing flyback transistor is a must .. & to find whether any other component is deffective or not completemainboard has to be checked ....... so if you are a technical person & having expierence in servicing line then you can do it yourself otherwise approach good tv service engineer ........... your TV is really very good one ... so don't think of buying new TV .... just goahead for repairing it it is worth & it works for atleast 2 more yrs....... try this & tell me what happened switch off your TV ... remove power cord from socket ,,,,.ware some mat or chapples to your feet ..... remove your TV's back side cover ......... observe carefully for any physically damaged components .... if you find then don't do anything ... close tv cover & approach tv service engineer ............. but if no physically damaged components are visible then take a suitable screew driver & rotate 2 (or 3) Knobs on flyback transformer in clockwise or anticlockwise direction - very little ( 4 or 5 degrees ) - you have to do this without touching any cable or any part of your tv .......... then fix..... back side TV cover ........connect power cord - stay at a distance & switch on your tv ......... if you get picture atleast for few seconds then in your case only flyback transformer needs to be replaced otherwise complete mainboard has to be checked. to find other deffective component ............. so your tv problem is a harware problem - it cannot be solved using remote control or any buttons on your tv ..... if you are finding difficult to get it repaired then you can remove your tv mainboard with the help of some technician & send to me ...... i will replace deffective components .... & send back to you ....you only have to bare the shipping charges .....it will take maximum 12days (5days - to recieve + 2 days servicing + 5 days to send back to you )....
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.
