Hello, my samsung rear projection tv stopped working. I replaced the lamp, still nothing. I then learned about the fuse. I found the fuse it was blown. I replaced it and when I tried to turn the tv on it powered up in standby mode. Then when I went to turn it on the fuse exploded. I replaced the fuse again and also used a surge arrester in the power point. The fuse still blew. Can you help me please mate? I would be extremely grateful. Thanks very much.

Hello you may also have a bad thermal fuse which is located above or to the side of the lamp housing, IF you are getting 6 blinks and then pause for 3 secs then 6 again, the thermal fuse is open and needs to be replaced.
Yes, you'll need to replace the bulb. Since no electronics stores stock rear projection bulbs, you'll need to look online for the actual lamp. You can get by for awhile by removing the lamp and blowing on it to remove any dust. I did this with mine, but the fix only lasted a few weeks. I was able to find a new lamp online for around $100 and my wife was able to replace it without issue.
There is a Thermal fuse under the lamp housing that opens up and Sony has a New style fuse to replace it with, it opens up one of the p/s lines to set code 6, replace with new thermal fuse and test. You will want a Skilled Professional to replace this fuse as it does require some dissassembly and removal of light engine to remove fuse from under lamp housing to put new one on side of lamp housing.
Sounds like a power supply problem.
I am sure that the pop is the fuse blown. If the fuse is blown, this means that there is a short somewhere.
Rear projection TV are like LCD projectors. And all of them use Switch mode power supply.
If you are lucky, there is a chance that a protection device (like a varistor) is sorted. This means that removing this, even without replacing will bring your TV to life, however...
Most probably the power supply is defective.
