• Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.
  

Have you got external loudspeakers that have dodgy wiring? Just a thought.

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)

What Transformer is that? It doesn't sound like a Sony Part #
The flyback transformer fir this model is listed below:

1-453-207-11 TRANSFORMER, FLYBACK NX-2609//X4C

Ur high voltage is dead,the FBT,the flyback transformer is dead,the big block of plastic with a red wire with a cap hook to a CRT(tv tube).

Ur high voltage transformer it dead.The big block of plastic with the red wire with a cap hook to the CRT(ur tv tube).It call the FBT,
the Flyback Transformer that thing it dead.

The hight voltage transformer it dead.The FBT(The flyback transformer is dead)The block of plastic with the red wire with a cap hook to the CRT(the tv tube).

You should post here pictures of old transformer and point out what wire you want to remove, then I can give you an idea what to do as flyback transformer is not in front of me.

The Sony part number for the flyback transformer is:

1-453-310-11

 

My thoughts would be, was it a Sony OEM transformer or a generic type? If the latter, that is probably a likely suspect. Another thing would be misplaced wires or switches that could have been accidently moved while replacing the transformer. I have had some of these sets that had no high voltage, and all it turned out to be was a broken solder connection on one of the pins going to the flyback transformer. Usually, if the flyback is bad, the Horizontal output transistor would be also defective. It's also possible that in the process of removing the old flyback (fun job wasn't it?) you may have cracked one or more of the circuit traces in that area of the PC board.
