These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times.

Replacement of color wheel is required expertise/ experience and professional will do that for you in correct and in safe manner. Contact local tv repair shop to get color wheel replaced in tv. Thanks.
There are three fans the one that usually fails is located on top of the optical block and cannot be reached by the owner unless you take the set apart yourself. What is happening is that one of the fans are not spinning fast enough or has stopped altogether. The best solution is to replace all three fans cleaning may not be enough to get a slow fan up to speed, and the tech should blow out the dust in the duct work. This is what the tech coming out will (or should) be doing. Also some fans will have an intermittent startup, and cause this intermittently, so it is a good idea just to replace the fans instead of just cleaning them.
Yes, its fan noise and you need to replace noisy fan. Let me know exact model of your Sony TV and need to know what fan is producing noise to provide you part number and parts shop info to buy that fan.
looks like the color wheel its bad in the set,color wheel its not spining at its proper speed( one of the segments may be broken)
thats the vibration you are hearing.. and the set its trying to turn on..until you replace the wheel you will be able to watch tv again.

The color wheel is the most common problem in DLPs that cause noise.
To determine the cause:
Turn the set off.
If the noise goes away after about five seconds, then, the problem is the color wheel.
If the noise goes away one to two minutes after shut off, then, the problem is a fan.
