Question about Sony SDM-HS73P 17" LCD Monitor
I have a Sony SDM-HS73 17" flat panel LCD that is malfunctioning on me. I usually keep my computer on all the time and turn the monitor off at night. When I tried to turn it on this morning, the screen came up as usual but then went blank after about 10 sec. The green power light was still lit but there was no picture. I turned the power off and then turned the monitor back on and had the same thing happen. I saw my computer screen (perfectly fine in terms of size, brightness, etc.) for about 10-20 sec and then the screen went blank again. Having some knowledge about computers, I tried the monitor with a different video card and on several different computers but still had the same result. I also called Sony, but since the LCD was out of warranty, then wanted a lot of money to send it in to get fixed. I wanted to see if someone knew how to fix this problem or if I should just ditch the monitor and get a new one. I think it is a power board issue, but I'm not sure. Any advice/suggestions would be most helpful. Thanks in advance.
The problem is with power inverter, usually the capacitors go bad and need to changed, they might be bulged and or leaking. Very cheap fix, less than a buck apiece and an hour with a solder iron. Google it to find more info.

Have a sony with the same issues, changed about 4 caps no such luck. Noted that the owner had the the brightness setting on high and the brightness control at 100%. Changed it to low light and brightness setting to 75. The monitor has of now been running for over half an hour. Will now resolder the transformers, do you guys think it is a bad or cheap transformer as there are no flyback transformers in these flat screens.
