I have a 19" Dell model# D1226H CRT monitor that started acting crazy a few days ago. Everything looks purple on the screen. I tried tweaking every button and dial I could find on the thing, I even hooked it up to different PC's. No Change. Two questions...first, what's causing thus? Second, would it be expensive to fix if it needs to be serviced?

CRT... perhaps something is internally wrong if it is acting the same on other computers. maybe one of the guns is ready to blow... it would most likely be expensive. try degousing it...

if not get a TFT LCD it would probably be cheaper than reparing your old beast. (that's just opinion)

If a gun in yoer CRT starts to go bad or is toast, You will lose Red, green, or blue..BUT generally when this happens you will see what are known as retrace lines.. Horizontally and diagonally on the screen.. If you know anything about video out puts on the crt board? check the collector voltages on all three transistors. IE red green blu.. If your CRT is bad 1 you have retrace lines and generally the voltages will be close in range w/each-other (usually around 200 dc) depending on monitor..if thats the case..Buy a monitor. If not email Ill check it out, you pay the shipping,, Ill fixit cheap. Ken..
