Re: LG 37LE500 lcd blinking

There are quite a few sellers on ebay for repair services of the LE5500 series (42LE5500, 55LE5500) indicating the main boards are susceptible to BGA failure. Reballing is the proper repair. Reheating may or may not have good long term results.

Ooops, I don't have equipment for BGA repairing
I think this repair is out of my scope
