The video and audio on my Sony TV (KV-32FS120) went on the blink and the standby light is flashing 5 times. The repair guys took the circuit board for 'analysis' and called to say that the flyback transformer needs replacement. My question is this: if I just buy the flyback transformer from them, can I replace it myself or does it require some special tools and skills? Just want to make sure the exhorbitant labor charge the repair guy is quoting is worth it.
Thanks for your help.
If you know what you are doing, and you have a good (de)solderstation, you can repaire it yourself, but you don't know if it for sure the transformer. since you did not find the problem yourself, suppose you replace the transformer and your TV does not work !?
Even when you repair it yourself, the repair guy shall charge you the cost for his time (I don't know the exact english word for his time checking the TV). And I suppose there is a warranty for his repair. So...

Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406audio 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.
if u pay attention the tv will after goes into shut down would go into dignoses mode , it would blink 6 - 7 times , stop and repeat againg 6-7 times this is high voltage power supply , the repair on this unit is very complicated but if u open this tv , look close tho the flyback transformer and next to it there is a small chip the part # start with (mz ) little black chip like i said is close to the flyback , it have like 8 leg on each side
The most common failures are the flyback transformer assembly and sometimes some of its support components, and or there is the possibility of a short in the CRT electron gun. In either case, the power supply is going in to protect mode, and the uPC is sending this flashing error code to the front LED.
I have no idea if the flyback transformer assembly is still available, but I am very sure the CRT is no longer available. In any case you will find the cost of servicing your set to be expensive for its age. The last time I checked, the cost of the CRT exceeded the replacement cost of the set.
If you have little experience of TV repair then take off back cover of Sony Kv-27FS210 and find Screen Control Knob on flyback transformer, turn that knob slightly CW or CCW and turn on TV to get picture. I think you need to turn ON TV few times to get proper adjustement of screen volts.
Above said procedure is for non-tech person. (Tech person will adjust screen volts (G2) as per procedure mentioned in service manual with proper tools.)
sony has problem with bad picture tubes as well as flyback transformers .if you have shorted hori output then replace it if set shorts it out again your looking at bad flyback transformer as well as maybe leaky tube.
This problem is due to moisture content in the flyback transformer surrounding area. Due to this moisture content screen control voltage is changed. Without getting a exact voltage the indicator will not stop. 5 times blinking is only for screen malfunction. Make one general service by cleaning the deflection area and adjusting screen control the problem is solved.
If the standby light is blinking 5 times then repeating, it is likely a problem in your picture tube or related circuitry. Other possibilities include the "Jungle" IC which takes care of the video, chroma and deflection processes and is a bear to replace. Either way, it could be an expensive repair.
