Lots of these sets had a issue with the door. There are two things to do to confirm if it is your problem:
1.) With the set unplugged remove the door and examine it sideways; you are looking to see if it is bowed or warped slightly.
2.)
The door has a plastic peg on the back that engages a small lever; The
lever connects to a safety switch--if the door is warped and that peg
does not engage the lever the set will detect "door not properly
closed" and a error code will be the red light on front blinking a
certain number of times and pausing and repeating this error code.
The
way to finally confirm this (I have done this myself) is to engage the
lever (usually blue in color and not large) with something plastic or
even a wood match stick.
Just do this long enough to see if the lamp comes on. IF THE SET WORKS THE DOOR NEEDS TO BE REPLACED.
Do not operate the set with the door removed or replace the front grill as the open lamp door could also melt the front grill.
DO NOT LOOK DIRECTLY IN THE OPENING IF THE LAMP COMES ON AS IT CAN DAMAGE YOUR EYES WITH THE BRIGHT LIGHT.
If
you find it is the lamp door confirm the actual model number and I will
get you a part number and where to find it at. Several vendors on
Ebay sell OEM replacement doors for most of these sets.
Let me know what you find and I am here to help you.
