I got an old DOS machine recently for free that seems to be working fine besides the old Trident ISA 2D card. I don't know what model it is but its 16 bit, and looks fine. When turning on the PC the monitor its connected to will display a black screen for a fraction of a second then lose the signalf. I don't think the graphics card is completely dead because removing it causes a BIOS beep code to sound, but putting it in allows the PC to turn on without any issues. I don't have a spare ISA card so if I want to replace this one I'll have to buy one. What I'm wondering is if there's some way to repair it, since the problem just seems to be getting the signal outputted. It's worth mentioning that I tried 3 different monitors but they were all modern LCD's, I saw it mentioned somewhere that some old Trident cards run a test to see if a display is monochrome or color, and modern displays can confuse it. I don't know if that's whats causing the problem or not because I don't have any old CRT's, only LCD's with VGA ports. Any advice on how to move forward?
