Last night, the C7558 capacitor removal fix allowed me to use the set normally, but now it's returned to the steady blinking. I did notice that there was a stripe of dimmer backlight going across the screen near the center.

Sir try to check the cables connection at the back of your tv. and if you are using a digital receiver, try to use a dvd to check if there is a sound. If there is a sound the problem is the digital receiver, feel free to send feed back good day and best regards.

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.

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