U have a thermal/intermittent issue. Given the age of the set and fact that other areas are now going, I think the cost effective way is to replace the set.

check the power supply, its not giving out the required voltage output. if you cant repair a tv plse take it to a workshop, ask a technician to make sure that he checks the following components.
power diodes and transistor, fusable resistors around the power supply, and zener diodes.
he should make sure that an ht of 95-110 volts appears on the line transformer. later a transformer will produce various voltages to trigger other voltages to open up your tv. thanks

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/

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described can't be fixed with
troubleshooting. Your TV will have to be repaired. There is a part that has developed a defect and needs to be replaced. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.

If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need one
circuit board or small part. If the problem is more than one of the circuit boards, the price of repair could go much higher.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.
