CDTV Capacitor list

Rate this Entry
I decided to recap on my CDTV, starting with the CDROM as it has difficulty starting, the front panel as the IR was weak and I am considering the PSU as well. As there doesn't seem to be a comprehensive Capacitor list for the CDTV, the mainboard, CDROM and the PSU I decided to document the values.

After the initial tear-down of the CDTV, I also removed the CDROM PCB, 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. Note there are 3 NON POLAR caps as well.Once I finished the CDROM and Front Panel recap, all initial problems were 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.

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.
