How do I fix my LC-60 sharp it's blinking 2 slow 3 fast

The 2 slow one long blink code for Sharp/Element TV's is backlight inverter over current/voltage shut down and not a board issue. Replace the backlights and the set should work like new

Sorry I don't work on Sharp sets so I don't know what the flash code means, do some searching online for what the issue is

Throw away product like most modern sets

Watch the video Sharp AQUOS power light blinks 3 slow 1 fast Fix

I have a 70 inch aqua sharp tv. The model number is LC-70LE857U. The stand by light blinks 2 times slow, 5 times fast. Tried resetting the TV.. Nothing changed. Please help.

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.

Follow as per attached file.

I had the same problem and the power light was blinking a specific code (3 slow and 1 fast). I made a video on how I fixed it.
