Sharp LC-46E830U 1-1 Blink with no Picture or Audio

[JoeyRoland82]

Hi All!

Recently, the power flickered at my mother's house and even though the TV wasn't on, it no longer powers up. When trying to turn it on, it has one "long" blink, (about a full second), followed by a short blink, (about half a second). I've been reading through these boards - including a similar situation in this thread - and was curious if anyone can shed any light. I've definitely a huge novice with this stuff but I have a multimeter and don't mind trying to get a learning lesson out of this.

For what it's worth, a TV repairman, over the phone, mentioned it was the "main board" and didn't sound interested in taking the job. He said these are pretty disposable units. But the earlier thread referenced above points to a bad LED strip or something.

Any thoughts? Help is very much appreciated.

Try to clear errors in Service Menu. Best Regards

try the "forced reset"... something like volume up, channel down keys at the same time while plugging in (check / confirm the exact sequence by doing a search). should reset any errors and possibly light up thereafter if you are lucky.... some have been.

Thanks guys! I'll head to my Mom's house this weekend to give this a go. I previously tried something like VOL+ and INPUT or something, but no luck. Should also mention the buttons on the TV are those touch buttons, (not the physical ones).
