TV turns on for about 5 minutes then shuts off.

The tv works and then shuts off after about 5 minute then shuts off. Then the green light flashes. After we turn it off it will turn on for about the same amount of time then it turns off again.

    Just a little more information. The sound shuts off a couple of seconds after the picture goes out and the light flashes green.

    I have the same problem. I saw on one of the sites that it might be the thermal fuse. I ordered and replaced the thermal fuse bu the problem still remained. It will actually turn on for about a minute, shuts back off, then on again for a minute, then shuts back off again... and the cycle continues.



    good luck

Tv turns on then after about 3-5 minutes shuts off and the green standby light flashes then afterabout 3-5 minutes tv turns back on


Most likely you need a new Lamp. This is a common symptom. I believe it is a XL2200 Lamp.
You could order it from Sony at 1800-222-SONY.
I hope this helps,

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!

Green Flashes - Shuts off


Sounds like the green picture tube is defective. To confirm you can take the front grille and door off and tap the green tube lightly with something plastic, and not to touch any of the adjustment controls to confirm.
