Hello! I have an interesting pet project to tackle but need some guidance. I have 2 MSC-4000 at hands. #1 is cosmetically damaged, has a slightly weird front panel buttons behavior, but works as expected (video+audio) after cleaning the corrosion on the back connectors. #2 is cosmetically near-mint, has a working front panel but outputs NOTHING on sound or video. So the idea would be to a) troubleshoot #1 and eventually b) swap the good parts of #2 to #1 chassis Both are the same B-version and revision, a few extra soldered patches on #1 than #2. Quick summary: trying to make a good looking/working MSC-4000 out of a broken but clean and working but ugly ones Julien

So far I got a fully functional MSC-4000 out of the 2 "junk" ones. Attachment:

MSC-4000 #1Front panel/buttons: acting a bit crazy + scratchesMUSE audio+ video: OKBack connectors: need corrosion clean up but OKChassis: mold spots + scratches+ MSC-4000 #2Front panel/buttons: OKMUSE audio+ video: No output on audio or video (faulty motherboard or back module fuse blown?)Back connectors: cleanChassis: rather clean and few scratches= Swapped front panel/buttons and chassis from #2 to #1 Front panel/buttons: OKMUSE audio+ video: OKBack connectors: need corrosion clean up but OKChassis: rather clean and few scratchesPlayed Silence of the Lambs, The (1991) [HVMC-12819] with it => flawless (both MUSE video decoding + analog audio from the MUSE decoder). Now... I need to figure out what's broken the the remaining MSC-4000. That will give me a reason to buy a new multimeter and since I have a working MSC-4000 as a reference, I can probe back and forth to find differences. Julien

Asked a High-end A/V shop nearby but they only had "Kripton" at rather crazy prices. Sounded a like a regular product repackaged as semi-snake oil for high spenders looking for magical artifacts. ( black diamond dust (黒色ダイヤモンド) as an abrasive! sounds totally legit - also increases USB Audio bandwidth!) http://www.kripton.jp/fs/kripton/audio_utilities/ci-g100Any regular/common corrosion remover?

That's basically it for corrosion (or any type of stuff really) on electronics, or is it something special you have to clean ?

yes Deoxit, my fast typing or dyslexia got in the way. I know that if you have sliders you should use the slider version as there is a brush?, but spray is fine for everything else.

Polished afterwards with a soft fabric. Works fine! Just need some alcohol to remove sticker marks and it will be go to go. Seems be called シールはがし (SHIIRUhagashi) here. Julien

For Removing stickermarks or all glue trace on anything, I use this : ぺべオ 筆洗い液 オドレスミネラルスピリッツ 75ml It works well, but be careful, it's hard for the hands, and breath.
