Did you have color problems in past? Most of these sets have convergence problems. Amps goes out. But you should have seen some type of distortion from color, red,blue, green. If no color problems then maybe vertical ouput out or horizontal output bad.

Be sure its blinking 5 times, count after it cycles the first time through the red lights. If it is fact 5 times, that is a lamp driver error.More likely it cycled 4 times, which is common on this model, if that's the case, then it's the fan. Most likely the large one in the rear...It's an easy fix, just pull the back off and replace the part.

Unplug the TV from the power supply. Never undertake any type of repairs on electric equipment without first disconnecting from power. Take care in handling any electric parts, as some may contain a residual charge that can shock you.
Remove screws from the back cover and connection area of the TV. Be sure to put them in a safe place, or on a piece of paper with notations for where each one fits in the television
Gently remove the back cover. Locate the mirror and three projection "guns," as these are what you want to clean eventually
Use a camera lens cleaning cloth (or other very soft and gentle cloth) to clean the mirror and lens. Gently remove any other dust before closing the TV.
Replace the back cover and screws. Plug back in the power supply
Turn on the television. Check to see that everything works correctly and that your picture is now clearer
