If the indicator light is blinking it is probably a faulty power supply. I just fixed mine today. Open the player up by removing the Phillips screws and locate the power supply board - this is the circuit board that connects directly to the incoming 120 Volt power. On this board look closely at the barrel shaped capacitors and note any bulging at the top of these capacitors. My 1000uf 16volt cap was just barely bulging so I decided to replace it with a piece salvaged from an old PC power supply. It is simply a matter of de-soldering the old piece and soldering in a new one. If you must purchase one you could probably get one from Radio Shack or Digi-Key for under a dollar. The replacement should be 1000uf and rated for at least 16volts or more.

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. Viewing it in "Mosaic" or "Magazine" will make surf easy.

Blinking codes details to many popular brand TVs are given. Surf the site with patience.
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electro-medical.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board....
