I have a question on a remote adjust board for a monitor. Each of the pots has a different value on it. Is this important or can I use any pot of the correct size if I need to replace one?

thanks
 
it's usually important to replace it with the proper size, although you can sometimes use a SLIGHTLY larger or smaller size if you can't get the proper size.

Let's explain why with two scenarios:

1) Let's say you need to replace the brightness pot, and it was originally 100k-ohms. All you have is a 50k-ohms. You may need 80k-ohms of resistance to get the brightness completely down. With a 50k-ohm pot, you'll never be able to reach the level you need, so your brightness may always be too high.

2) Let's say you need to replace your horizontal hold pot, and it was originally a 5k-ohm pot, but all you have is a 100k-ohm pot. Your horizontal hold may only lock in between 1.8k-ohms and 2.1k-ohm. For a 5k-ohm pot, this range is close to the center of it's position, and you will be able to turn it a little in that range without it losing the hold. With a 100k-ohm pot, that same 1.8k-2.1k range will be a super-tiny spot in the complete range of the pot, and will be very difficult to hit when you try to adjust your picture....
 
yeah, and you can cook smaller ones too, so be careful.

The one that is broken on my adjustment board has a 24 silkscreened on the one side. The closest that I found was a 23 on another remote board

does that make any sense?

The second number is the number of zero's:

24 = 20000 ohms or 20k-ohms
23 = 2000 ohms or 2k-ohms

Most likely the 23 pot will not give you the range you need....

Crap and I just gave away all my other monitor chassis.... Dang.. So a 53 is actually a 5000K ohm... still not big enough.

Actually, 53 is 5000 ohms, or 5k ohms.

If you have anyplace around that sells parts (Fry's, Alltek, Radio Shack) you can check to see if they have the one you want...
