Question about Televison & Video
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)
