Have a Mitsubishi TV Model #vs55705 about 10 yrs old. TV worked last night and today it doesn't. Green light goes on for about 2 seconds then goes off. I have tried many times same thing happens. I checked the fuses (4) of them and they tested good. I am not a TV repair man. Any ideas what could be the problem, please give me a answer.

You've answered your own question!

You're not a TV repairman, and you've checked the obvious things that a non-repairman can check. So now it's time to get an expert to look at it.

There are hundreds of components in a colour TV set, and the failure of any one of them might cause the set to not work. You need electronics knowledge and a circuit diagram (schematic) to find what's failed.
