ok, i need help with this iMac G3

[coius]

I dug my Mom's iMac G3 out of storage (In the basement). Anyways, upon booting up, i encountered the video only using 5" across of the screen than the screen is. I don't have an OS so I can't try software calibration

I think this is more serious than software. I have reset everything like PRAM or NVRAM or Power Manager. It doesn't budge. I am going to try to get a system on it with the screen being like this. But it's going to be hard with everything smooshed

I am going to go locate the iMac's Disc.

FYI, this is a 400Mhz FireWire DV

The system has been stored upside down in storage (No idea whose bright idea THAT was) and I think the gun is off. Am I right to assume this? Would this be easy to fix? Mind you, i don't have a problem with going into the monitor. Done it before, so If I have to pull the whole thing apart, i can.

Also, i don't think it's the PAV. There is no whining, and the screen is perfectly bright. So there aren't any signs of it being that.

I'd let it sit for a few hours, then turn it on and let it run for a while (an hour or so, let it run a screensaver or play a movie if it's got DVD). If the screen doesn't come around, there could be a few different problems.

It seems that the horizontal part of the screen, doesn't want to work. I have tried to adjust it with the controls on the tube (i have it taken apart, and it lets you adjust the give on how much you can control the screen through software) and it looks like something on the back of the tube isn't controlling the horizontal definition. The screen displays crisp as ever, but I can't move it out to the left or the right, and I can't rotate or pincushion it. It this a dud machine?

it's stuck like this:

[ ) ( ]

the "[" and the "]" are the physical sides of the tube, and between the "(" and the ")" is the picture that work. Vertically, I can adjust it, but the horizontal part sits dead.

I have a feeling that it being upside down all the time musta really ****ed it up

question, does the metal cap at the back come off? and is there any adjustments in that?

I would be a little hesitant and want to see if someone has made a venture into something like this before. I also notice there are little "Arms" around the tube. I don't want to touch them right now, but can they be used for calibration. To give you an idea what these "Arms" look like, if you look at the neck of the tube, you see the flat things going down to the rings that go around the tube. I am not sure what they are for, but I am wondering if they can be used to control various parts of it.

Is this a slot loader? If it is, I would just recommend getting another one. When a SL iMac's CRT starts failing on me, I go find a decent looking 350 model and swap out the HD. If the model you have is 400-500 swap the board out between the two. If it is >500 ... Right now I have a 600 waiting for an atx conversion because of it.

I would suggest getting a 15 inch LCD and fitting that inside the case, that's my plan when mine dies.
