Sorry for replying to a old thread but I think you can help me.

I'm currently fixing a Sharp LC40F22E that has no standby light and doesn't turn on. It has a 17PW82-2 PSU, 17MB60-4.1 Mainboard and a LTA400HM07 Panel.

I have already repaired the PSU and now receiving all voltages but the fault still exists and think the Firmware could be corrupt or the Mainboard is completely dead. There is one on eBay but would like to try flashing the spi chip first. Do you still happen to have the Firmware you flashed?

Hi my name is Dan, I'm from England. I found this forum while fixing a old sharp tv.
