It would power up and show the display for a second or so then go dark. He was still in college at the time and didn’t want to fuss with it so he bought a new 20″ LCD and gave me the old 19″ to look at and try to fix. It sat in my garage for months collecting dust and getting dirty.

Tonight I decided to pull it out, clean it up and see what was wrong with it. Sure enough it was doing the same thing to me. I tried different cables and power cords with no change. After some Googling I found this.

It seems that the capacitors on the ac/dc inverter go bad and cause the backlight to not work. After pulling the case off and stripping the LCD down, I find that of the 4 capacitors one has popped. After some more reading It seems you can get replacement capacitors pretty cheap online.

I only had one capacitor that was defiantly bad but because of how cheap the parts were I decided to get replacements for all 4 capacitors.

I ended up with 470uF 25V High Temp Radial Capacitor x2 and 1200uF 10v Capacitor x2 shipped for under $10.00.

Once the parts arrive and I solder them in I’ll post an update but I’m sure that $10.00 worth of parts just fixed a $300 monitor.
