the problem may be due to dry soldering in the power supply stage if it was with the lamp there would be red or green light showing the presence of the power to the tv after making it own some of the components get hot and it will make the the soldering point conectionless and after some time the heat sink get cooled and the soldering point gets connected and u will see the picture again it is a simple problem if u have a soldering iron u make it hot and re solder all the components in the first part of the circuit board and the problem if rectified
I just took my Mitsubishi WS-65315 65" in to be repaired for the same problem and was told that it needed a new main circuit board part number 930b899005 as was told they wanted to charge me $1100.00. So I told them not to do the repair and picked up my tv and found that same part at Sears parts for only $225.00. Some of these TV repair places are theifs.
