@@Fallacy99 Not at this time. Trying to find service data to do some bit bashing. I can tell you what it isn't. Not the digital filter, not the da converter.
Interesting, can't wait to find out the solution. I'd rather deal with soldering chip leads than with those tiny smd's so prevalent in modern components.
There will be if it ever gets fixed. Still sitting there on the shelf. Owner wants it fixed but there is a problem finding service dats and he doesn't want to pay much. Digital filter and da converter chip has been replaced , reads disk, data there but no sound. Need manal to start but bashing.
THEtechknight The other unit was fixed due to the fact that the CD transport chip was bad in that one. It didn't have a DAC due to it having no coax outputs, thus it couldn't be used as a parts unit like what was originally planned. The Philips ended up becoming the parts unit in that case. Both units were eventually restored to working order.
I have a Sony PS-X75 turntable, that is known suffer processor chip failure. I haven't used the turntable for six years. (Never had time to set it up while taking care of family.) I will replace caps in the power supply before I apply power. Apparently, bad caps can cause over-voltage and blow the chip. I'll also re-lubricate everything while I'm inside. From what I've seen, this is not trivial. The chip is unobtainium. I read where one person was able to replace the processor with a Teensy++ 2.0 board. It took him a while to program! My thinking is that if the chip in my machine is kaputt, I'll try the Teensy. I'll probably order one just in case it fails in the future. It's getting harder to find micro-controllers that handle 5 volts.
THEtechknight Environment is the big factor. If you allow smoking or burning candles in your home the laser will fail sooner from particulate contamination of the optics usually. Same goes for wood burning fireplaces. Cooking isn't as much an issue because your CD player is not generally over your stove. I have CD and DVD players that have run 24/7 for years. Before the raspberry pi came along I had an aquarium video running constantly to amuse my kids when they were little. The laser never did fail. The spindle motor did. .
Yea that is true. dusty environments, etc. I ran into a Sony CDP-770ES on my bench, the glue that bound two halves of the prism together actually failed and fogged up blocking the beam. First time I have seen that. As far as DVD players, I have never had a DVD player last more than a year or so. I ended up getting rid of my DVD collection because of the players. Of course most of the players were walmart specials. the DVD drive in my PC lasted longer than the actual players.
Wouldn't a chip socket be better at this point ,in case the chip didn't work ,so you won't stress the traces anymore,and who cuts out a chip? I found a very cheap little solder sucked about 8.00 dollars ,it always leaves a clean hole when done ,it you want I send you a picture ,I like it so much I bought a spare,
IMO, it isn't wise not to install a socket for IC's like those to prevent board traces and via's lifting/damaging on these consumer cheapy grade circuit boards. I modified/upgraded many of these Philips/Magnavox players back in the late 80's early 90's and that was the first standard course of business (including soldering in OP-amp sockets for testing various ones. You should still get a real desoldering tool like a Hakko FR-300 and you'll never go back to de-soldering braid. Contact Hakko USA and I bet they would send you one for free (thus promoting the product). Lots of YT guys get free stuff that way...
Mmm, a good old Philips R2R ladder DAC, that's definitely a deck to repair! Hard to come by R2R ladder DACs anymore, everything is cruddy delta-sigma. :/
The soldering of the pins and the speed was just incredible to watch thanks for sharing your skills.
Wow the laser moves in an arc never seen that before. How common was that design?
That was the first design used in philips decks. cdm 1,2,3 and 4.

I think the shop you are talking about is "Ted Mack's A-H Repair, We Fix 'em". Great Video!
You'll be looking for an SAA7220 (the filter and oversampling chip)... Appearantly still available on ebay... The DAC is an TDA1541A S1 (expensive)
You could try putting the unsoldered chip into the parts player to see if it fixes that one.

Spoiler alert. That is the next video.

@@12voltvids Scope the RF for alignment of the "eye pattern" like you did in your Rotel RCD940 CD player repair and alignment video @7min 39sec.
The RF is fine, signal is string, and focus is good. It reads fine, but the data is not being decoded.
just picked up this unit, has a bad on/off switch and the cd drawer sometimes want open, are you still looking for one ?
Nice soldering demonstration.
You have a lot of patience !
Look at the quality of the chassis, solid metal, none of this horrid plastic here
The CD880 is a much sought-after player. On eBay one could easily fetch hundreds of dollars.

No follow up it was scrapped
Was there ever a part 3? Can't find it.

@@12voltvids Thanks for the reply! I like your videos!
I am sure you probably tried this, but what happens if you stuck the "bagged" transport chip into the other unit? did it restore its operation?

do you know were I can get a audiolab 6000cdt cd drive?
Sorry have no info. Anyone?

Hey could you re-post part 1 again !! Thanks !!
It's still up.
@@12voltvids thanks, it was under 2 cd players on bench !! I'll let you know how it goes, same unit LoL, same audiophile !!
@@slayerb576
I may redo that one as a seperate one. That player never got done. I told the owner to take it away.
@@12voltvids I liked your " married to it" term lol, a tech budfy of mine has it from me from a friend of audiophile guy !!
12volts what ic is it i have scrapped a few cd players and kept the mainboards i may have an chip i can give you
Hmm... looks like some of the pads lifted - >Erk< I hope those aren’t needed! 😬 Or maybe it’s just covered in old rosin.
The problem with CD players and CD player collecting is the lasers dont last forever. Sad fact. :-(

Maybe it needs a SID chip from a Commodore 64! 😆 Just kidding.

Yup. They have their own sound thats for sure.
The DAC chip is $60 +. Not worth it in my opinion.
It's a really good Philips R2R ladder DAC, it IS worth it! I'd drop the $60 in a heartbeat to fix that unit.
Too each its' own.
Owner of the set is also prepared to drop some coin on this one.
I stand corrected on my previous opinion. Hope an original chip can be sourced.
