If there are any electrolytics caps on the inverter board, I would try replacing them first. You may find similar model for sch here: http://www.eserviceinfo.com/index.php?pagetogo=1&what=search2
In the ENTER? box put in 'lcd monitor', Mfg box put in 'SAMSUNG'
Those surface mounted electronlytic 100uF25V caps usually do not show sign of bulging but if you heat them up with hair dryer and the circuits start working then I would try replacing them. I cut the body off but still leave the two leg attach to the board, then you crack the plastic spacer off then it will be easy to unsolder one leg at a time, I then use standard through hole cap, just cut the legs short and bend the end of the legs to fit the footprint and solder. You mat also want to make some resistance reading of the inverter transformers.
Hi, if you have this monitor and LSP115AVA, is it then possible for you to give me a partnumber on the cable going out of the LSP to the monitor?
