The power supply is in the process of failing.
I'm pretty sure the problem is caused by a 50 cent (maximum!) part called a capacitor in the range of 4.7 - 100 uFd that is responsible for feed back that keeps the power supply ticking. If you decide to have it repaired and the problem is as above, tell the tech to use a low ESR part and add a .1-.5 uFd ceramic capacitor in parallel to the one he/she replaces. That cap will handle the fast rise times that causes the electrolytic cap to break down chemically and fail.  

Before you toss it out, just take a few minutes and do searches here at Fixya on rear projection, LCD and plasma TVs. The failure rate across all brands is staggering and many of them are suffering the type of problem you are currently having but seemingly the majority are under two (2) years old. If you do decide to replace it, due diligence may save you a lot of anger if you check to see how the model or brand you are interested in is faring. I have one Wal-Mart turkey (iLo) that is a miserable conglomeration of cheap parts and unpredictable performance.

The 2 blinks is a diagnostic code that should indicate the problem circuit. This is unique to each model though. Can you confirm that the model in question here is KV-32FS120?

Thanks,

Sony wega trintron wont turn on


Most likely there is a failure in the power supply or in the scan amp sections. This will require factory level troubleshooting to determine where the faults are.

This type of service may be on the expensive side.
