Question about LG Flatron L1710M 17" LCD Monitor
MONITER TURNS ON AND SHOWS A COMPLETLY NORMAL SCREEN FOR 1/2 SECOND THEN THE SCREEN TURNS BLACK
HI. I had the same problem with mine. It would flash the screen on for a split second and then turn black, the whole time the power light remained green. Upon opening up the case, I pulled the combo power supply board/inverter board out for inspection. I noticed one of the capacitors had a bulge on top indicating it was bad. It was the the 680uf 25v capacitor. I desoldered it, and soldered in the new one. After hooking everything back up, bingo!! Monitor now works perfectly. I couldn't find an exact match to the capacitance locally, but I had a 1000uf 35v cap in my utility box. It worked fine as a replacement. You can usually go within 30 percent of tolerance and be alright. Just don't go under on capacitance or voltage. I hope this helps.

Backlight is bad and needs replacing! When the screen is black with no image. Most of the time it is the inverter, when the screen shows an image it is the backlight, if power light flickers it could be a combination inverter board and backlight!
