I have an EVS-modded 963sa.

I installed it on a switched outlet and would turn it on via the switch. The IEC cord always had a loose fit and had to be pressed hard to make contact, and would make a crackling noise when inserted.

It worked fine for years, but at some point turning the switch on no longer turned the player on consistently. At first it was coming on 75% of the time, then 50% then 25%, then zip.

Contacted Rick at EVS and he said it's mostly the switching power supply, and the only way to get them is out of a working unit.

So, does anyone know if it's possible to buy just the PS from somewhere? Or any other suggestions on how I should proceed?

BTW, the machine + mods cost me around $1100.
get yourself the cheaper second hand DVD763 SA. PSU board is exactly the same as in DVD963 SA...

I don't know the DVD47, but the Philips is one of the best sounding DVD players around. Still I would not advise to buy it, because it's very unreliable!

The only problems I've seen with the DVD963SA are with the power supply and having replaced the original capacitors and done some other mods on that board they are solid machines. The laser can be a fit fussy with very badly scratched / dirty discs.

Well, I had 3 of these players, which were all crappy. And talked to the guys at "Van Medevoort", who adviced against any mods, because you would not be able to enjoy them for long anyway....

The PSU is crap, but the transport is even worse. It's my only player that acutally stops working during winter or summer, because it's then under 15 or over 25 drg C, and it won't load CD's. (DVD's will keep working). Putting more or less load on the top plate will help. Shaking the whole player will help as well.

Well, even tough I think the transport is crappy, i did do some mods on my 963sa. It was a player already modded by Art-Speak. (at least that is what the seller told me). They added loads of bitumen, changed 3 caps, removed the label of some others (why???), and placed non-conductive sleeving over all ribbon cables (to make it look pretty?). Last they glued the 24MHz x-tal. All toghether is sounds a bit better than the stock player.

Last week I replaced the final opamp with an AD8599 low noise opamp (that one works good at "low" supply voltage). I replaced the dc-blocking elcos with Wima MKS. I removed the extra "stereo" output opamp and switch. I removed the opamps for the SCART interface, and the whole SCART board. Last I removed the Progressive Scan board.

The result was impressive!! The sound is no longer thin, but very smooth. Detail was kept at an high level, and the bass improved alot.

Because I read the power supply was not very good (switched) the next step was to make a new symmetric power supply. I made one using two LM329s as a shunt (with random PNP/NPN power transistors) and about 1000uF of elco's. I did the same for the 5VA (analogue power for the DAC), but used a normal zener. The new supply is for the opamps and the 5VA.

The result is mixed... the bass improved alot, but the treble is a bit muted, it sounds a bit dull. Soundstage is worse than before

What could be the problem?

why do you need the firmware? And how do you want to load the firmware is the laser is broken? Flashing went via CD-Rom.

By the way, second hand value of a DVD763SA is about 30 euros in perfect condition, so why the trouble?

Some update about the player dvd763sa it is in the software, de dvd reads data in memory and decode there, I did stop the disk for a momente and dicover that it happens in the firmware, software who decodes mpeg video, so firmware is needed and I cant find it.

the new laser is from a xbox game player, costs 11 euros and plays flawlessy, it is a toshiba laser.

http://www.ebay.nl/itm/310260549421?...ht_3358wt_1139

Now I play a movie with verbatim, these plays total errorfree, a laurel and hardy movie, original also get,s the hickups, the other hardy movies who are from the same producer plays without error, I also saw that player when fault jumps to the next chapter.

see movie here what it does. http://www.youtube.com/watch?v=UekWNURF5DY

I have read somewhere that er was a fault in this firmware about chapter problems.

so nieuw firmware is needed.

An update about the dvd763sa the problem of skipping and hanging are over.

A little print underneath the lasertransport motor was fallen of his place the bold was loose.

this print has a little ic who act as a feedback trough a magnet, it reacts on magnetic field.

I have put it back and new bold, after that there is no skipping anymore ocurred, there was soldered on the little print so I think it was defected en replaced, for people who has this also remove unit and look at it bij the little motor.

the software assumed that there is a signal also from that lasertransport motor who he not get, and so that can be the reason of crash of player.

Now I can listen to it, but until now the sound is very hars, it has nothing whatsoever of quality of my NAD HDCD player who has all burr brown ic,s.
