Replacing led strip(s) in a Sharp Aquos LC60LE600U TV

SOURCE: sharp aquos lines threw the picture

I've seen this problem before and if caught early (usually only a few pixels), its fixable. But if it has already started forming a "line" it might be too late and you might have a defective LCD panel. Most of the time, doing the factory initialization helps with this problem.

1. unplug tv
2. press and hold at the same time “Vol –“ and “input” button on the TV set.
3. while holding those buttons, plug the tv back in
4. the tv should turn on by itself, keep holding the buttons until the letter “K” appears. Then let go
5. then at the same time press “Vol –“ and “Ch. Down”, you should see the service menu appear (if it does not appear, try pressing the two buttons again, it needs to be exactly at the same time)
6. Then use the “Ch. Down” button to navigate down the service menu until you see “Industry Init” (NOT Industry Init +cause)
7. Then press “Vol +” to toggle it to “ON”
8. Then “/////////////////” should appear.
9. when the screen turns GREEN, unplug the TV. Wait about 30 seconds, then plug the TV back in.
10. Then continue on with the initial setup again.

Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu.
I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!

2. pressing channel down and volume up buttons at the same time while plugging tv back in
3. if you here a click, the tv has been reset

I had a similar problem. Fleeting video, then audio only for few seconds and then nothing except the green power LED blinking on and off.
I changed the power inverter board, backlight inverter boards and power supply board but still the problem is not gone.

Just 18 month old TV and out of warranty.
