Help with Sharp Aquos led error codes

Hi there, BigBadBill! Is "Aquos" the entire model name/number? I get conflicting info in my searches. Anyway... came across a few posts describing issues with blinking LED's. This one seemed particularly relevant:

'The frequency and color of the blinks will indicate the issue. There is a hold-down button sequence to try to backdoor your way into the set to see if the panel will light. You may have simply racked up too many "weird tuner faults" and need to reset it. My suspicion is that it's either that or bad panel backlight.

Unplug set, press and hold (on set) volume-down and channel-down and hold them while pluging in set. Will come on with "k" on screen, or will crash again if backlight bad. If it stays on, use your remote and arrow right then look for "fact init" and any other reset and turn them on. Arrow back up to "fact init" and hit enter. Let set recycle to green and unplug/re-plug in 5 seconds: the set should be in OOB state'

Thanks Lou, I spent a bunch of time searching with different combinations of words and found nothing of use.
I will give it a go this weekend. :T

You're most welcome, and hope it helps. Please let me know. If not, we'll try something else!

Ok, I reset the unit as per the article four days ago, with one small change. The TV is plugged into my Belkin Surge Protector so I couldn't easily turn it off and on.
Instead I held the power button in for five seconds until I heard the click which said it had fully powered off. Then I held the vol and channel down buttons and pressed the power button. I didn't get any error messages it simply came on with a black screen and then after about ten second functioned as normal.
After it came back on I set it back to the Onkyo HDMI input and it has been working fine ever since.

Anyway, thanks again for the info Lou. :T

You're welcome, and good to hear you solved the problem!
