Replaced Lamp and it worked for two days but then got 3 blinking greens and 2 reds, after a day of this no lights come-on. The red will come on until I press the ON button and then no lights at all. Unit is 2yrs old.

First check if you had tighten all screws after replacing the lamp as it may cause loose connection and also the lamp panel is securly in place or the micro switch may be the trouble maker. You need to have some one switch the tv for you while you are looking into the set from the air vents closed to the lamp without opening any panel. Make sure you plugout and in the tv to power source with every attempt. See www.fixurtvs.com See if the lamp comes on for a second or two and goes off.or never comes on. If while switching on the lamp comes on and goes off quickly when seen though the back cooling vents and there is no momentary whining sound you have a color failure. If the lamp is not coming on at all check again on lamp specification/part # and your installation and if every thing is okay, exchange it from the seller and try new one. Most sellers like www.fixurtvs.com will have a respectable no questions asked warranty, Hope your problem is resolved quickly.
