Hi folks,

I have a Philips CD620 which has (possibly) the same fault as Graham's Orelle described in this thread:

http://www.diyaudio.com/forums/digital-source/171326-cd-player-distortion-laser.html

Unfortunately, I only have a CD630 service manual, although the boards do appear to be similar.

However, the DRAM chip has a the following printed on it: "8928 USA" then next line "MT 4416L-12".

Is this DRAM equivalent to an MN4264P that is listed in the CD630 manual? I have obtained one, and they do appear to be the same size. Googling unfortunately produces no answers.

Thanks for any help!

James
