Blue light and lamp light flashing, no picture.


Look in the owners manual for the directions on how to remove the lamp. Your model the lamp goes in from the front on the left looking at the TV. There is a thumb screw in the back on the corner holding the left front speaker on. Under the panel there is another thumb screw holding the lamp door on. You will need a Phillips screw driver to remove the lamp. You will most likely find that the lamp is bad. You will either have to order a lamp directly from JVC, a service center or a parts distributor.

Blue light in the front blinking no picutre no sound


This is the shutdown code for the lamp ballast. I would have a technician verify ballast is bad and replace. This can be a tricky repair for a novice because installation of the ballast requires that you remove the light engine. Hope this helps.
