CDTV Capacitor list

[Beltalowda]

I am about to undertake a recap on my CDTV, starting with the CDROM as it has difficulty starting and the PSU, just in case. Does anyone have a Capacitor list for the CDTV, the mainboard, CDROM and/or the PSU?

If not I will update this post once I open her up, and add what I find.

NOTE: Thank you for all the replies, I think this will become valuable thread for any CDTV owners.

UPDATE: Just finished a tear-down of the CDTV, and it was a real pain to get to the CDROM PCB, got there eventually. Looks like my CDROM PCB has had quite a bit of rework, an IC was added on a separate board and an additional capacitor was added. See attached images. The capacitors are all low profile/short except two near the power connector, but I have included the sizes in the table.

UPDATE2: CDROM and Front Panel Recap done, all initial problems fixed, non spinning CDROM and weak IR. Note there is a hidden capacitor inside the shielding for the IR on the front panel. Its a pain to get into as you have to bend the metal shield open to replace the capacitor. I have also fixed the PSU capacitor list as it was missing one cap value and two caps were mislabeled.

I only know of a list for the CD-ROM:

https://www.a1k.org/forum/index.php...9a8rIFKvGlAvGjMhIkc_Um-qbLUTDwO9pPPn7rRpBRrPw

 

[Tuxbar81]

Here is the list for my CDTV set.
I have to complete the capacitors list of the PSU...

 

[nrc]

Hey, thx for sharing!

 

[Tuxbar81]

No problem!

I've forgotten to mention that 3300µF must be a low profile capacitor.

Diameter: 18 mm
Height: 15 mm

I'll open it again to take the values of all PSU capacitors.

 

[Beltalowda]

Finished the PSU Caps list except 1 cap next to a transformer wrapped with plastic and glue, may have to remove it to identify it. Does anyone have a clue, its C103?

 

[Beltalowda]

While recapping the CDROM I realised that C205, C218 and C208 are all NON POLAR Electrolytic Capacitors. I have updated the initial post/list and will return to the electronics store soon!

 

[Beltalowda]

CDROM and Front Panel Recap done, all initial problems fixed, non spinning CDROM and weak IR fixed. Note there is a hidden capacitor inside the shielding for the IR on the front panel. Its a pain to get into as you have to bend the metal shield open to replace the capacitor. I have also fixed the PSU capacitor list as it was missing one cap value and two caps were mislabeled.The unknown capacitor next to a transformer which was wrapped with plastic and glue, has been identified C103 - 10uF 50v 105°C

Hope this this thread is useful for anyone having CDTV issues or wanting to do a recap.

Wow, thank you. I will be attempting to repair one or two of my own CD-ROM drives at some point. Unfortunately a couple of months in the future at the earliest, but this information will come in very handy! I will update my experiences here if and when I get around to doing the actual recap job. Once again, thanks!

What is spec if the hidden IR capacitor?
I previously had gave up to replace it, but knowing it's possible I will try to replace it.
I also missed that glued PSU cap
Thanks.

See the table below, it's a regular (small size) electrolytic cap, I have named it CIR.

Once the IR module has been desoldered and removed, carefully lift up the 4 securing tabs inside the shield (green arrows), then you can lift the last piece (blue arrow) covering the IR sensor itself, and finally lift out the module.

Thank you for detailed explanation.

Btw if you or someone else needs.... I successfully replaced CDTV laser with SF-87 4/11. It requires soldering because CDTV uses 5/12 connectors, especially lines to laser require modification as in this picture.

It's quite a job getting into CDTV CDROM, but I have learned a lot in the process. If you would like any guidance or have questions when you go ahead with it, just PM me.

That's awesome, thank you for sharing this information. I know as time goes on, spares will become more and more difficult to get and possibly be unreliable. So thanks again for the info!
