Wont power on and no lite on front power button.I check fuse by power cord, it not blown tested the fl231 fuse section, all three show ok.not blown.no lites in either tube.any thoughts.also where's a good place for diagrans for the board free or cheep.

you can temporarially. Its recomended not to exceed fuse ratings especially the amperage do to pretective reasons. You can get the proper FL231 fuse at the following link. They have a 10.00 minimum order for free shipping so you may have to order enough fuses to add up to 10.00 or pay for shipping if under 10.00 Heres the link. http://servicemanuals.vstore.ca/
THe rca itc222 chasis has No convergence ics it uses a series of transistors to do the same. YOU replaced the Fl231 fuse and it blew. Did you resolder flyback connections. this is why the fuses blow. check out the article under the tips and tricks section written by me willtab ... see if this helps if not let me know .. i see alot of these at the shop ( i got one right now in front of me with the FL231 probelem LOL) if can let me know i give you help
You most likely need a new convergence power supply board if fl231 keeps blowing thats the most likely cause, also check for shorthed capacitor cp231. If you need a link to get a replacement convergence power supply board, let me know I know where you can get them.
the rca itc222 chasis uses no stk the convergence is controled with transistors... the convergence amp board is located above the main signal board(green board)... it can be identified as the one with several heat sink fins on it. FL231 is related to convergence.. there has been a problem with this fuse when it blows the processor doesnt know it is a projection set so it turns it into a regular tube tv. Here at the shop we have found number one reason this fuse blows is poor solder connection on the flyback. So replace the fuse and reflow the solder connection on the flyback and around that area also the horizontal transistor and then see if that doesnt fix the problem.. if you have an more trouble ..... email@example.com
ok since you have checked the main glass fuse on the little board toward the front. You have no flashing led on front of set. this is an indication that you are missing the voltage to your processor. also known as standby. fl231 and the two other little brown rectangular fuses can be blown and the set will still come up and shut down. Are You a technician? The next step i would check is to see if your getting 320 volts out of your main doubler... CAREFULL VERY CAREFULL this will hurt you. so if your not tech.. dont do it.
