Hi everybody,

I opened up my eMac to replace some capacitors. But when i closed it back up my colors are shifted.

I'v got a 1px blue line at the left and e yellow line at the right. So its a bit hard to look at the screen.
Did i bump in to something?

Does someone know how to fix this and if not anyone know a site or forum that can help me?

"Replace some capacitors?" What does this mean? What were you trying to do? I can only assume that you are an EE and know what you are doing if you are "replacing capacitors."

The eMac uses an old CRT type screen. CRT means that an electron gun makes a coating on the display light up. You have three colors - red green and blue - and each has their own electron gun and their own wire mesh to shoot through. What seems to have happened is that the blue gun has shifted to the left, and needs to be recalibrated.

On external CRTs, there is generally a way to do this with knobs on the inside of the display casing, but how one might do this on an eMac is more than I know.

I'm still a student but replacing capacitors isn't that hard and it a known problem with the emac that some capacitors start to leak.

Ok thx i'l try to find out how to calibrate the screen. I think i know were to look, can i calibrate when the screen is on so i can see if its working? And yes i know i'l be careful i know that there's a 10kV on the screen .

I found were i can do it but i cant get it perfectly rite but its good enough for me i'm not looking cross eyed anymore.

For the people who maybe have this problem to there are 3 plastic screws on the top of the screen witch you can use but these may not me enough. There are a couple of plates at the back of the screen witch you can turn if you loosen the big whit one first.

Maybe not the best explanation but i did the best i could do.

The three screws sounds like what was I was thinking about. If they're not enough, then you really have banged into something, but it seems that it's good enough now.

Just two notes if anyone else reads this and decides that they want to try it:

* Opening a CRT is dangerous. You can get a shock even if the CRT is off and has been off for a long while. That shock can kill you, if you have some sort of heart condition, and will make you wet your pants. Don't do it if you don't know EXACTLY what you're doing.

* When adjusting knobs like that, always mark their initial position first. That way, you can at least go back to the default if you mess up.
