I have one question since You had mostly posted what I need to fix my RCA D61W20.I unsoldered flyback and have it ou.Had a heck of a time w/ focus leads ,but they are off.
Now alls I need to know to re-install flyback is how much actual wire is suppose to be exposed ?When I pulled out of old flyback had just under a 1/4 of an inch exposed,but don't know if part of it might have snapped off inside flyback.TIA.

Replacing the flyback is the most dangerous part to replace on CRT sets, because of the high voltage lead that plugs into the tube needs to be unplugged. the tube will hold 20,000v+ at any given time.
If you are OK with this then what you need first is a Flat head screwdriver and a alligator clip. clip one side of the clip to the ground that goes around the tube (silver wire wrapped around tube) then the other end on the metal part of the screwdriver. Now slide the screw driver under the rubber cap on the top of the tube and lift so you can the the lead under the rubber, the touch it with the screwdriver to discharge the tube, now unplug it by wiggling it from left to right as your pulling. Now only 2 more wires. the other wires go to the crt board, one may be soldered in, you just need to unsolder it. the other wire will be inside the white cap on the crt board. there well be a lever thing that goes up or down right by the wire, move it and it will release the wire. Plug all wires back in from new flyback
Now you must unsolder the old flyback and solder the new one in. after that is done turn the set on. dont be worried if no picture, Sonys need to be adjusted sometimes. try turning the knob on the flyback (the one on the bottom). try to get it right in the middle, and set should come on, then adjust for brightness and focus (top knob)
Hello: The first thing is optaining the exact replacement part. Next there are approixmately 12 pins on the bottom of the deflection board where the part is located that need to be unsoldered there is a slightly thick red wire coming from the top of it that goes into the splitter block and a thin red one that goes to the focus Block, each need to be removed. To get to the focus block the lower front cover of your television needs to be removed Reverse the procedure to install the flyback transformer. You may want to purchase a soldering iron and some solder wick, commonly known as desoldering braid from radio shack.
first check all fuses they are small, square ,RED and can be confused with the square small caps. the sizzling is prob. the flyback transformer (what the h.v. wires from each tube plugs into) if you are only getting green then tv shuts down or is dead now. i would replace any bad fuses and replace the flyback transformer. also make sure you do a very good visual inspection of all the boards.
I read the other post you made and I don't belive that the flyback transformer has gone , and these models and makes from rca do have some common fixes that are found out by tech's . this problem that you are having can be in the power section , stanby circuit , protection circuit or even a horizontal output IC or some component that is causing the set not to come on . the flyback transformer would need to be tested to determine if it went bad but the power section would need to be tested first because there are different voltages that come out of the primary transformer and they go to different parts of the tv's functions and circuits , also info like what happen when it went out? and or was there a problem with it while watching it before it went out? , this can help to know what section was failing , thus start the testing in that section.
the best thing to do is to call an electronic repair shop to have a teck come out so they can determine the failure for you , as these are pretty complex sets and unsoldering and soldering , testing of and value idenentification of components is required , so if you cannot perform these then you could be putting alot of money into it and never finding the problem.
if you would like any more info , I'll bee glad to assist you
very simple fix there's three micro fuses beside the flyback transformer if the center fuse is open check with meter then theres bad solder connections on flyback simply resolder flyback in board &install new fuse. the 3 fuses are brown or tan about a 1/2" long
Check for solder cracks around the flyback and around the line coil next to the flyback. If that doesnt help go to this link as you will most likely need a flyback they have them and offer free assistance. http://servicemanuals.vstore.ca/
