Fault with main board. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/
Repair work to Philips Brand TVs is a skilled one. It will be best to contact any service technician, in this case.

Over-Current Protection (OCP). Simple as circuitry shortage to power supply. You would need to have this serviced by a trained technician. This is not something that you want to try to service on your own. Consider your opportunity cost when servicing this item. If it costs you half of what you paid, you might as well purchase a new monitor.

the picture comes for 2 secs on the screen and immediately goes to stand by and red LED Sony bravia standby mode blinks 8 times

Replace C2465, C2508, C2540 and C2541. Replace with 25v /105*C types.

The remote control will not operate the TV when the TV is in the OFF mode (No LED lit on front bezel). To change the mode from OFF to STANDBY or ON, press the POWER button on the side of the TV. Once the POWER button is pressed, the LED will change to either red to indicate STANDBY or green to indicate ON, whichever mode the TV was in prior to being turned off with the TV POWER button.

By pressing the POWER button on the side of the TV, the mode will toggle from OFF to either STANDBY or ON. If the POWER button is pressed and then the LED on the bezel is red, the TV is in STANDBY mode and will need to be turned on using the remote control. If the POWER button is pressed and then the LED on the bezel is green, the TV is ON.
