bbking67 Posted January 10, 2012 Share Posted January 10, 2012 I just scooped a Commodore 1084S (for $10!!!), and it works. However, the color is not very vibrant (I am using the Chroma/Luma mode). I think I have everything set up okay (the three buttons on the backj are pushed in). Basically the color at the max is not quite enough... on my Commodore 1701, I can put the color in total saturation mode... comparitively, max on the 1804S is about the one third setting for color on the 1701. the brightness seems okay. It's not razor sharp--kind of a soft image, but not really blurry and totally acceptable. is there an adustment that can help me? Or is this symptomatic of a failing monitor? /bbking67 Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted January 10, 2012 Share Posted January 10, 2012 (edited) Not sure about the colour saturation comparison (never owned a 1701), but I have two 1084S monitors (a D1 and a D2) and the pictures on both are kind of "soft" (at least when compared to a Philips CM8833-II). I reckon it's the tubes (Orion), but if it was really blurred (which you say it isn't), you could always adjust the focus pot on the flyback. It's also possible that the phosphor has degraded somewhat, or there's a degree of magnetisation on the tube (and this is where my "knowledge" stops!). Question: do you have any dark, speckled areas in the corners of the tube? Just curious, since both of mine have.

bbking67 Posted January 10, 2012 Author Share Posted January 10, 2012 (edited) No dark speckled areas that I can see. I might try and adjust the focus, but it's okay, just not enough color. the guy I bought it from said that he used it as a TV for a few years, so that probably put a lot more hours on it than if it had been exclusively a computer monitor. I'm really crossing my fingers that I'll be able to boost the color because it's a nice monitor. Edited January 10, 2012 by bbking67 Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted January 10, 2012 Share Posted January 10, 2012 At least using it as a TV would minimize the risk of burn-in. I'm certain you can adjust the RGB gun intensity by opening up a CRT, but it's not something I would attempt - the risk of completely screwing the calibration is probably great. They are lovely monitors, these. Well worth saving. Quote Link to comment Share on other sites More sharing options...
bbking67 Posted January 12, 2012 Author Share Posted January 12, 2012 Anybody have an experience with this increasing the intensity of the RGB gun? I really would like to use this monitor... Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted January 12, 2012 Share Posted January 12, 2012 Can you post some photos of the picture? Quote Link to comment Share on other sites More sharing options...
+Mitch Posted January 12, 2012 Share Posted January 12, 2012 The tube may need to be rejuvenated. You might be able to get it done if you can find a tv repair place. Mitch Quote Link to comment Share on other sites More sharing options...
