Re: Sharp LC-46DH77S Communication error? Bad main board?

Hello!Sorry the website administrator but I can not open a discussion for which we did not quite correct! I have a Sharp TV LC20AD5E-BK no longer work at all. We measured a signal diode FCF10A20 as quickly. I replaced it, now TV has sound and sees weak negative image without LCD backlight. I do not know what to check. Please help me with advice, for which I thank you in advance.
