Looks like a power supply trouble or capacitors not good. Has to be open and check by a pro. Good luck,

Hello Sagar,
green led means tv powered on and status ok.
Red blinking light almost always means defect, overcurrent or overload.
6 blinks for Sony lcd flat tv means trouble in backlight circuit, or backlight inverter (backlight illumination or lighting makes your tv screen visible).
common problems in the inverter circuit, which drives the backlight, or shorted drivers, or short-circuit transformers or open circuits.
You should find the problem in the inverter circuit, or in the power supply board or in the main board.
Also look for bad capacitors (electrolytic caps) which are bulged and swollen on top.
Decoupling plugs from printed circuit boards can help you in finding the problem board by elimination method.
If you power up the set after unplugging certain plugs on f.e. the inverter board , this could result in getting a green power led and concluding that this board is faulty.

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 stage 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, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

Hi i have seen this before sharp hdtv's are known for having the internal power supply go faulty

I have a 50" Pioneer PDP-503MXE with the same problem - the fans don't run. It appears to be a problem with the temperature sensor that controls the fan speed. However, the fans can manually be switched to MAX.
To do this, put the display in standby. Press the 'Menu' button and within 3 seconds press the 'Power/Standby' button. The 'Integration Menu' will appear. Select the 'Option' tab on the right. Scroll down (next page) to the 'Fan Control' option. It will most likely be set to 'Auto'. Press 'Set' to change it to 'Max'. Within a few seconds the fans will run.
At Max the fans are a bit noisey but it will cool the unit down.
