    A few months ago while watching TVmy screen started fading out and turned black, you could hear sound but no picture, so I turned the tv off and turned it back on and it was fine, it's been doing this on and off for a few weeks, but Now it completely, won't turn on and the 3 lights on the front just flashes, so I replaced the lamp and two of the lights stop flashing and the one light that continue to flash was the lamp, but it did that for about 3 minutes as if it was going to come on then then shut off and restarted doing the same thing about three times then all three lights come on again, so what could be the issue?

Often when two of the three lights are flashing-- the back cover of your lamp may not be in all the way. There is a sensor that tells the board when the cover is put back on so you might also have a broken sensor. If the cover is completely screwed in-- try asking a pro.

First you want to check the lamp, if you see the set from the front you want to go to the left side(on the side not the back) and you will see on the side lamp cover only one screw remove it and you will be able to see the back of the lamp 2 screws take lamp out and inspect it , if bad replace it. some sets will have lamp part number on the side also.

I have a Samsung HLN437W 43" wide screen HDTV Monitor TV with DLP Technology. The tv picture will not come on. The three light in the front of the tv are all flashing (1 red and 2 green). I live in...

All you need is a new lamp thats what the 3 lights blinking is indicating. Very easy to do this yourself. Just order a new lamp and let me know when it arrives and I will explain how to change it. Very easy takes about 5 minutes.
