I should have thought of this sooner.

I have enclosed a photo of my NTSC A1200 near the RF modulator. I can see that my caps have different values, although there are similar in appearance. This is from a Rev 1D.3 board.

Am I already recapped?


The big blue cap seems bulged, or its just the angle of the photo....

All joking aside, those look like the originals. I'm with ASCII on this. Then again, I won't confirm. I haven't seen the insides of a 1200 for 18 years.

Think you might be right but the angle is doing something.

I'm going to crack open the case and take a closer look.

Were you referring to my photo or the previous post?

If mine, it could be due to dust. I took this photo a while back before I did some cleaning.

I will have get some better photos when I open the case again.

The reason C237 appears to be bulging is due to the curved line on top. You can see it easier in the second photo. The surface is flat, however.

How in the world do you get access to this cap? It is very close to the keyboard connector.

Nice work!

I see that removing part of the keyboard connector gives you some more room to work with.  :D

In some ways, working with surface mount components is easier provided you have the right tools. I do not have a heat gun or a fine tip soldering iron with precise temp controls, however.

I'm surprised the heat gun did not cause damage to the keyboard connector. Guess you just have to be careful.
