Green in the corner of the tv

It sounds to be a firmware trouble. Will be best to contact the authorized service center for Sony, rather than trying to do it by yourself, as it is a very skilled work, need both concentration and previous experience. google.com/+GopakumarGopalan

It looks that the green video output section have the fault. Check all the components there.

I have a older 2006 SXRD rear projection TV. I had the same problem after the TV warmed up this yellow tint started in the corner and crawled its way down the TV. It turned out that Sony had a recall on the optic block of the TV. If you replaced the Lamp and adjusted the color this kinda sounds like the same problem. Here is a link explaining it. In this article it shows up as a green haze and blob, but in my TV it manifested as a yellow tint.

Turn on the tv the green light will blink many times after that How many times the red light blink

You have a leaky capacitor in the high voltage section of your tv and it will eventually fail completely if not replaced. This is not an expensive fix $50. ballpark

lamp needs replacing

there is a part inside of your tv called COLOR WHEEL probabbly is damegad you need to replace that part.

overheating

"Will Not Work"
"Bad Move Buddy"
"I'm All Done"
"That's All Folks"

Any of these will do, in reality, the set isn't going to power on as you likely have done some serious damage to the main board or tuner, etc.
