TV repare TV will not come on you push the power button and it will light up than start blinking than turn off

Samsung told me this was a common problem and I would have to have it serviced by an authorized repair facility.
My problem ended up being the internal power supply, but they also told me the main boards burn up.

5 times LED blinks in Panasonic PT-47WX42 shows problem with convergence out chips failure as this tv has two big black ICs STK392-110 as convergence output, replace them to fix tv problem.

what is the model of your tv?

I have this model of the sharp tv.Happen to me very often the Power and OPC LED light indicators blink continueosly.Not the power supply board,it the Tuner board that take in the comming broscast signal that have the problems.You still can used this tv.Push the power button sometime the tv it will work right away.Not,each time POWER and OPC lights continueosly blinks.Just push the power button again each time the POWER and the OPC continueosly blinks.Just have push power button again about 4 times each time Power and OPC blinks recycles,it will finally show the backlight and picture come on.My guest,if u do this by pushing power button to recycles about 10-12 times each time the POWER and OPC blinks it time to change the Tuner signal board.

Those 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.

If blinks continue without any pause, the main board is faulty.

This is usually an indication of a failure in the scan amplifier sections. When the scan amplifiers or high voltage sections fail, the main power supply will usually also require servicing.

It is very common that the fly-back and high voltage multiplier and also the horizontal output stage fails in these sets. Along with it, the power supply will usually require to be serviced. On rare occasions, the vertical deflection amp fails.
