Yes, look for two 1000uf capacitors on the power supply PCB near the output cable to the main PCB. They will have swelling and discolouration. Replace those and should fix your problem.

White spot at the bottom of my samsung sync Master 153v monitor.it is quite disturbing please help in sorting out the issue


is it a large spot or just a pixel??
if it a large spot most likely the screen has been damage in someway, either something hit it and damged the lcd. if it just a pixel there nothing much you can do but replace the whole screen.

the same goes for the larger spot. you just have to replace the screen.

check on ebay for prices you can get a good deal.

My samsung sync maste 740n lcd monitor is not getting on properly.. its getting on very late..i.e after 30min i need a solution for this... plz help me... venkat 09866046610


Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.
