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.
Blinking codes details to many popular brand TVs are given.

This is its power supply regulator problem itself. If any resistor [used in the start section circuit] has developed high value, or has a loose solder terminal, this could happen. If you wish to get some details, check the site linked here.Pull up older posts.

Average life on a OEM or original lamp is 2000 hours---about 2 years depending on how much you use the set---only real way to know if lamp is the problem (other than looking to see it is not shattered inside) is to replace it---either it is or is not the problem.

When did you replaced lamp in tv last time?

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Good luck.

Thanks for using FixYa. To reset the TV you’ll need to disconnect the TV from the power socket and mains, remove all the cables from/to the TV and let it without power for about 10 minutes and after it plug all the cables back and switch it on. To replace the lamp use a Philips screwdriver to open the small square shaped lamp compartment panel on the side or back of the TV and pull the lamp out slowly to remove it. Now clean the lamp holder and new lamp with a micro fiber cloth. Please make sure to turn off and unplug the TV for at least 1 hour to drain off current from all components especially capacitors before you perform any repairs. Also note that the TV consists of very high voltages even when it is in off position. Before performing any repairs I’ll suggest you to try and reset the TV by unplugging it for 8-10 hours. Please do accept the solution if the issue is resolved or post a comment for further assistance.
