WD 52525 No picture

I have a WD 52525 replaced the lamp and still no video. I do get audio. Green timer lamp blinks rapidly on supplying power to the TV for about 1 minute, then I get the solid green, at this time I can turn on TV, still have audio but no video. After a few minutes red lamp light comes on and TV shuts down. I have to disconnect and reconnect power before I can get to the green blinking light again. I am being told the replacement lamp is good. I have tried the reset button and the audio/video reset (device and guide buttons at same time). I have owners guide and service manual downloaded. But haven’t found the answer yet. Is there something I am missing or doing wrong (hopefully) or is this a much larger issue? Is there a lamp timer reset that I am missing? Any advice would be much appreciated. [email protected]
