Re: Help Identifying Which TV Board to Replace

Vinceroger69, sorry for the wrong description on the "main board". Here is a picture of the actual main board that's under the metal cover. It has no power anywhere on it.

Thanks for the help so far....

Hi. I have a Sharp LC-C6577UM TV that won't turn on after a lightning storm. It acts completely dead. The power button or remote won't do anything. I don't hear any clicks or see any any lights on the TV.
