I got a contact from Lexicon Italy (I am from Italy) and they sold me the last 25pcs they had in stock. They were original HY53C464LS-10.Thanks for the reply. Did you find any in Europe? Right now eBay seems like the only option. And how did you figure out you only needed to swap out 5?
So either; U64,65,66,67,68 or U93,94,95,96,97? Mine has the NEC D41464C-10 does it matter if I go for that or the Hyundai?I got a contact from Lexicon Italy (I am from Italy) and they sold me the last 25pcs they had in stock. They were original HY53C464LS-10.
I chose to replace one full channel at first and I tried to see if the issue was gone. And it was gone. I could probably substitute less than 5 but I decided to go full channel.
Exactly. If I remember correctly U64-68 are the left channel RAMs and U93-97 are the right channel RAMs.So either; U64,65,66,67,68 or U93,94,95,96,97? Mine has the NEC D41464C-10 does it matter if I go for that or the Hyundai?
Thanks for all the replies! Happy the thread isn't dead.
Unfortunately I don't know... I'd suppose that it could affect the stability of the system.Thanks! I have someone close to my area selling 4164B-12, is it safe or might 120nsec be too slow?
The service manual says:Another 480 with problems here. I repaired the powersupply, also found one bad tantalum on the motherboard. I replaced all the tantalums on the motherboard with electrolyrics. The 4 leds on the host go out after start up as it should, larc is intelligent. Output gives very loud noise with some kind of reverb, you can hear that if you change parameters. OVL leds stay on, the vu meters work according to the input. Self test of the motherboard give a clean dry signal but the OVL leds stay on. Extracting neither HSP doesn't help. Extacting both HSP's OVL goes out but of course unit says: not enough hsp. Any ideas?
The self test of the motherboard is the same that you specified. Sorry for misunderstanding."Self test of the motherboard (the jumpers) give a clean dry signal but the OVL leds stay on."
Generally you get all ones when reading from an unpopulated chip.Interesting. I will try that in the comming days. So I have to worry about the DRAMs. What will happen if I leave out the DRAMs of one channel?
