    If it is the vertical lines, then the LCD T-CON board is bad and it is part of the LCD panel, new panel will have to be replaced, it will get worst with more lines.http://s807.photobucket.com/home/budm/al...

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.

Samsung sync master 740N no display. Flickered started then the display goes after its been on for a short wile. Could this be a problem with the capacitors?


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.

Problem with display of Monitor


Hey Mate, its either the graphics card of the monitor. both can give you that problem, first thing i would try is open the base unit and take out the graphics card and refit it, see if it fixes your problem or test another monitor on it. Second if its the monitor your best to send it back to samsung as it they honestly aint worth fixing, will cost you probably more than the monitor is worth, we used to sell the samsung syncmaster monitors and they were nothing but hassle, its the only monitor we ever sold they we sent about 70% of them back for dead pixels, or just packing in for one reason or another. All the best John
