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?

Sorry, I mistyped that. Meant to say it had numbers that differed from the other poster.

I thought they looked similar enough to be considered stock also. Good to know.

Same values, just diffrent voltage. Its okay for voltage to be a bit higher or lower, as long as its within the range still. The uF  no, needs to be the same. You look to have the stock caps in an NTSC model too. The Shoei ones are at least.

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

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

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

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.
