Depending on the type of TV, the longevity can be affected significantly. If your TV is a plasma model, they run very hot and the plasma only lasts about 4-5 years. That is why plasma is no longer being made by any of the major manufacturers. It was state of the art when it came out, but now LED TVs are the standard. They use much less energy, run a lot cooler and last much longer.
Longevity really depends upon the technology used, not always who made it.

Replace HDMI cable first, then check whether your box works on HDMI out. Try connecting box using other out (USB, VGA, DVI, DP, cable)

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.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
