For several months, after turning the TV on it would turn itself off shortly after and then turn itself back on shortly after that. Then it would repeat that several times before finally staying on. Last night this happened again but it did not come back on until it did randomly 5 hours later at 4 am.
Hi there,
If the tv is still under warranty, this can be repaired at no charge.
However, if not under warranty, you will need to have the CAPACITORS on the main power supply circuit board tested (or replaced).
The capacitors responsible for the power supply can sometimes fail - open the back panel. If the capacitors on the main power supply board look too fat, or signs of burning near the solder joints, then you've found the problem.
Hope this helps.
Cheers,
Scott

This is a Heat issue with the front sensor of the TV. Dust and Dirt block the sensor causing it to heat up faster and faster. Cleaning the lamp is extremely easy and it will get the TV working again, at least for a short while and then it will happen again. I know cause its been happening to me and it will work for about two weeks and start happening again. Sony actually has a class action lawsuit against them for this issue. Long story short here are the steps to correct the issue:
1. power down TV and disconnect from the power outlet then let sit for 30 minutes until its colled down
2. On the bottom corners of the TV (Back side) you will find a round screw that you can loosen with your fingers
3. once both screws are lose the front bottom part of the TV will pull off, there are magnets there so it will hold it in place temporarily.
4. Once the cover is removed, in the center of the TV will be a little door with another Finger screw to loosen, once off move the bar holding the door closed and remove the plate.
5. You will need an Alan wrench, the screw will be in the upper left corner, when this is loosened the screw will not fall out and you can pull out the Light fixture
6. CAREFULLY with compressed air spray the light assembly and the inside of the TV very well and then replace the light bulb.
7. Put the Door back on the front of the Light area, and assemble the rest of the TV in reverse order before testing the TV. I have done this multiple times as this is not a permanent fix but does restore life for a short period of time.

This is due to bad caps read here what a cap is www.badcaps.net see you tv is getting hot as normal but the caps cannot stand it any more thus shutting the tv down. The bad caps would be more or less in the power supply unit of this TV. So you can buy a new psu or get it repaired by a expert.

SOURCE: TV Turns off and on
How long since the last time the bulb was replaced? It sounds like the bulb is overheating and triggering a safety shutdown.
It's probably in need of nothing more than a good cleaning (open it up, clean off the boards with a can of air) and *may* be time to replace the bulb.

How old is this TV and when did you replaced lamp last time?
