Question about Sony FD Trinitron WEGA KV-36FS120 36" TV
Tv turns its self off and power button led light turns from green to flashing red my tv is only 2 to 3 years old and i payed about £1.700 from new tv is only on at night times except over the last 5 months it is on in the day as well please help me its doing my head in thanks
From the symptoms you describe, it seems the high voltage flyback autotransformer has failed along with the horizontal amplifier (they are slaved to each other).
Well, the only way to solve this is to get a technician take a look at the set, I'm afraid. Repairs could cost upto $100 or more, depending upon the number of components that need to be replaced,
Since the set is new, it may be worth getting fixed up. If you decide to do so, call around, as shops have different rates and different expertise. Many shops are hurting for work because so many of the smaller sets are never repaired anymore; they are just thrown out and replaced since the cost of a new set is sometimes as low as the repair expense.
Hope that helps...Should you have any further questions, please feel free to post them here.

I had the same problem. Changing the LOPT will work but it will only buy a few months use. The problem is with the tube itself.It would need to be regunned. If the tube has done more than 20,000 hours then it will be worn out. There is a built in diagnostic that shows how to do this here
There is a site here that has a picture of the lopt component and it says that it failing was a common issue.
