I'm from the DIY projector fourms on this site and have a question I thought you guys might beable to help me with.
I have an LCD monitor that I bought broken, backlight doesn't work. I found a surface mounted transistor on the inverter board of the LCD that was humming, looks to be arcing internally. I can't find the actual transistor anywhere (jameco, mouser, digikey, and some others) as expected. The transistor outputs somewhere between 500-2800 volts, and my multimeter can only measure up to 500v. There is an identical transistor on the board and I was wondering if I could put a resistor accross the one that was working - so it ouput less current and voltage, and then calculate what it acutally ouput so I could attempt to find a replacement transistor.
If I'm totally off base here, or in way over my head just let me know.
Thanks in advance guys,
Eric
