Sharp LC-60LE640U 2 slow 2 fast blink code repair

[tibimakai]

I have picked this TV up a couple of days ago for $25(!).
It had this error code, with no image or backlight.
Found a repair kit online, which showed a coupe of parts and board designations as well(sorry I can't find it again).
Checked those parts, except the IC and found a shorted NUR460 diode, D7805.
By replacing it, with a MUR460(left over from another similar repair) fixed the TV.

That is one of PFC diode, so you did have the Boosted Voltage, right?
Actually the MUR460 Diode fails a lot too.

The boosted you mean, the 170V? That one it was there.
This diode it was marked as NUR460.

I also have a shorted D7805. I ordered a 20 pack of MUR460 to replace it. I hope it is the only issue. I checked a few other parts, but might have missed some. I also have 2 long and 2 short blinks.
