Is it poet supply problem

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

Manufactureres usually keep their schematics to themselves however you may be able to contact them to purchase a new power supply.

The blinking red light signals the fact that the power source is in protected mode - it's fully functional (as the green light also shows) but has been shut down by it protection system.
The protection system of the source is engaged when 2 things happen: either there's a short on one of it outputs (you will have to test the output voltages to identify the failing board and from there if the board can be repaired - start with the inverter) or if the processor can't load the firmware - this is almost always caused by a hardware failure of the processor and in that case the mainboard will have to be replaced.
In that case it will cost you around $200 to get a replacement board, plus the labor. Now you must decide if the tv is worth that amount of money - in my opinion it doesn't.

Look for Bad Capacitors they will be vented or swollen on TOP.

Sounds like main board fault. 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.
