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. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

Warranty is probably not an option anymore, and replacing the bulb could be a costy gamble, even when done yourself. It's probably the electronics. Since replacing those is more expensive than a new TV, I would suggest giving up on it. Sorry :(

It likely has more than one, the main fan should be right at the lamp inside and another should be on the digital board, most of these have at least two fans, got some issue?

Hello, I'm sorry to tell you that that set has a bad optical assembly. The blue part has gone bad and cause's either a yellowing of the screen or blue spotting or both. You can purchase a new lcd tv cheaper than you can repair that one. Do not replace the lamp, it's not what's wrong with it, and you'll just waist your money. thanks, Terry

The simple test I would make is hook something to the rear audio and video inputs and see if when cold you have the problem there.

If your main signal in is via the cable fitting make sure cable is connected and if the set does not display the issue via rear audio/video jacks you can (most sat and cable boxes have this) route your signal via an unused set of audio and video jacks thus bypassing the tuner

download this manual
see page 59,60,61,62. The problem can be the lamp
After extended use, if the TV picture turns dark, the color looks unusual or LAMP INDICATOR light turns on, then it
is time to replace the lamp with a new lamp.
