I have this IBM L170 monitor which started to exhibit the 2 second on then black symptom. an electrician was replacing a light switch in my son's apartment and turned the breaker off. when he was done, he turned the breaker on, now the monitor will flash the IBM logo then go black. it keeps recycling with the same results.
I was able to verify in a darkened basement, that when the screen goes black, with a flashlight I can still see the IBM logo at a reduced brightness, then the screen will flash the logo at normal brightness and keep cycling. I can turn the monitor off by holding in the power switch.
all this is done without being connected to a PC.
The 5V and 13V are there. no bulged caps. it looks like the inverter is part of this power supply. the PS is made by samsung and the model is # IP 35135A. the pic below is a picture I copied from another post, disregard the black circles on the pic.
am I looking at a defective inverter in the PS?
Thanks to everyone on the forum for any help you can provide.
