Hello, I got this unit that has corrupted graphics, and replace both memory chips, doublechecked all the connections with multimeter and everything seems fine but still has corrupted graphics, so maybe the problem wasn't the memory chips, so what else I should look for. Thanks.

Could be a bad trace to one of the memory chips. Check traces from memory chips to the HU6270. If traces check good, then maybe a faulty 6270?
