PT-50LD54 is an LCD rear projection TV with a consumable bulb that wears out normally after 2-5 years of use.
Most likely you need a bulb. That is first step in any troubleshooting for that tv. Check out Panasonic Gallery to identify lamp and replacement bulb.
Changing bulb involves removing the lamp assembly and replacing the bulb in the lamp assembly. Like doing a puzzle. Requires philips screwdriver, pliers and patience. Don't have jam on your fingers when you do it.
We have a PT-50LC14. We replaced the lamp 6 months ago with a TY-LA1000 bulb we bought from a company online (not directly from Panasonic) and it worked for 6 months. Then the TV started turning off on it's own...sometimes it would not come back on for an hour or so. We called the lamp company and we luckily had 1 day left on our 6 month warranty!! They sent us a replacement bulb and the TV would never power on. It would try to power up, but the bulb would never ignite. The power light would flash and then the lamp light would flash every 5 seconds. I had a friend that has the same type of TV and she ordered her bulb directly from Panasonic. I borrowed her lamp and it powered right up. We then called the online company and they sent us yet another replacement bulb, and I tried it today and it works. It seems like these TVs are very particular about the type of bulb used. Next time, we will be ordering ours directly from Panasonic and just paying the extra $100. We have been without our big screen for 2 very long months! I had called a local tv repair shop, called Panasonic directly, and read through countless internet forums, and I thought we were going to have to replace the ballast or get a ballast repair kit and start messing with the circuit board.
It sounds like the lamp is in need of replacement. You could call a service company to replace the lamp, but it is so easy to replace the lamp ones self. So, call Panasonic and order the lamp, they will send to your home with instructions.
Three screws and your home free!
Good Luck, Big Irish.
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.
