Title: Re-cap WG 4900 question... strange cap value
Post by: breathsavers on August 13, 2013, 07:51:29 pm

I'm re-capping my monitor board and from what I've read, C506 is supposed to be a 22uf, 250v cap. However, the cap I pulled off my board in that position was 47uf, 160v. This seems strange and I wanted to make sure I was ok in putting the "correct" cap to replace it or if I should go buy a 47uf cap since that's what was on the board.

Also, C366 has a resistor on it currently instead of a capacitor...

I don't have a loose 4900 in front of me to check values, but I have found incorrect cap values installed on more than one monitor. Sometimes it is carelessness, sometimes it is part of some mod that was in Star Tech Journal back in in the old days (in which case there will often be other components that are different than stock).
