You need to replace the power supply board. The new ones have a bigger heat sink - obviously JVC knows about the problem because they made the new ones bigger. It cost $250 from JVC and I installed it myself - took about 3 hours to do. If you are not tech savvy call a repairman. Hope this helps.

Power led and lamp led blink simultaneously on my jvc hd65s998 rear projection tv


You might need to replace your lamp driver, or ballast as some call it. This is what strikes the lamp to make it light.
