I Have A Sharp Lc42 D65 Unit With Sound But No Picture. The Power Light Is Stead
When the unit initially failed, the green power light was flashing. I tried the reset steps discussed on a number of internet blogs. That resulted in the power light becoming steady, but still no picture. A visual check of the inner workings did not reveal any obvious defects
