I have a ViewSonic E390 that even when the brightness and contrast
turned all the way up the picture is still dim. This reminds me of the Dell P1110 Trinitron that a friend has that suffered from a similar issue except that in that case the monitor was too bright. In that case the issue could be easily repaired by increasing the value of a resistor (or was it a capacitor). Is there any chance that there is a simple cure for this monitor like there was when I fixed that P1110? Although I'm sure that someone will tell me that my 19" CRT has had a long good life and that I should replace it but I'm not in a position to do that right now unfortunately Thanks in advanced for your time. --adam |

I'm not sure if it matters but the monitor is not an E390 but and E790.
Thats what I get for covering the model number with a Debian sticker. Sorry for the confusion. --adam Adam wrote: I have a ViewSonic E390 that even when the brightness and contrast turned all the way up the picture is still dim.
