Symptoms include: No power and if you have two or ten blinks on the front light. After I have removed the power board from the panel, I will start removing components. The first piece that I will remove is a heatsink. I am starting by desoldering these points on the bottom side of the board. I will use my desolder gun to heat up the solder and then the vacuum in the desolder gun sucks up the excess solder. You could also use a solder sucker or solder iron and wick. Some of the solder points may be difficult to reach. Use caution to not damage the board, and if needed remove other heat sinks to gain access to the solder points. I have flipped the board over and will now pull out the heat sink. Again, I will use my desolder gun to release the smaller satellite boards from the power supply. Those boards are green and have highlighted them with a red circle. After I have desoldered the satellite board, I can reach under the power supply and free that satellite board. I will repeat the same process on the other satellite board. We do not show it in the video, but after desoldering the satellite board, I will gently pull it loose from the power supply. I will need to remove this heat sink from the board, so that I can access the solder points underneath it. I will flip the board over and desolder the heat sink by desoldering these solder points on the top side. I can wiggle the heat sink to loosen it from the board. Next, I will desolder the fuse solder points on the bottom side of the board, then remove the fuse from the board. Next, I will use my solder iron and solder wick to clean up the pads on the board and remove the excess solder. I hold the wick on the pad and then apply pressure and heat with the iron to the wick. I will clip the wick as I use it to get a fresh piece every so often. After I have cleaned up the pads, I will put the fuse on the top side of the board and push the legs through the proper holes. Then I can solder the legs to the board using my iron and solder. Be sure to clip the legs close to the board. Next, I will solder the large heat sink back to the board. When replacing transistors, you will want to bend the pins to match the transistor you are removing. This is important, because it allows the transistor to fit through the board properly. To remove the transistor, use the screw driver to unscrew it from the heat sink. Then you can screw the replacement transistor in the same spot while pointing it in the same direction as the original. After that, you can put the heat sink back on the front side of the board and slide it through the holes. I will solder the heat sink on the bottom side of the board. Again, be sure to clip the legs after you are done soldering. Next, I will use my desolder gun to clean the points of the satellite board. I will place my tweezers onto the capacitor on the satellite board and use my heat gun to loosen it from the board. After it has loosened, I will lift it from the board with my tweezers. Since the heat gun melted part of the mat on my desk, I will place the satellite board onto the heat sink on the board. I am using the heat sink as the platform because it is metal and will not melt. Normally I would use my pre-heater, but not everyone will have a pre-heater. When removing the IC from the satellite board, I will place my tweezers on the legs of the IC and then use my heat gun to heat up the component. After the IC has been loosened from the board, I will pull it off with my tweezers. Then I will use my solder wick and iron to clean up the pads. Next, I will apply some solder paste onto the pads for the capacitor. I will use my tweezers to hold the capacitor in place, while I apply heat with my heat gun to secure the component to the board. After I have placed the IC on the board, I will apply pressure with the tweezers to hold it in place and then run some solder flux over the legs. Then, I will add a little bit of solder onto my iron and then run the iron over the legs to solder this side.

Comparison of Kuro 9G (PDP-LX5090) plasma & 2011 Panasonic PDP drive method
In this comparison, the stark difference between the two panels is quite visible. The Kuro uses a sequential sub-drive method with short but numerous subfields (28 SF on normal mode, 14 SF on energy save mode.) The subfields increase linearly in intensity. In the Panasonic drive method, the subfields vary significantly in size and they are scattered across the overall frame. Also, the dithering in the Panasonic is considerably more aggressive although is visually less noticeable compared to the Kuro. The primary advantage of the Panasonic drive method is flicker and power consumption are both considerably reduced. Also, the more optimised phosphor, with higher efficiency is visible. Of particular note is how the red phosphor now decays very quickly, with the green also being improved somewhat, reducing motion blur and eye-scan flicker. On the Kuro, the red and green phosphors decay slowly, resulting in the panel appearing to alternate between blue and yellow (in reality, the red and green simply decay later causing the tint effect.) The main disadvantage is that odd numbered subfields cause "dynamic false contouring", which is a fancy term for making moving objects look like they are an oil painting with multiple bands at colour transition points. This only happens in certain scenes and movement rates but is a small penalty for an otherwise improve drive method. This is one of the coolest things about PDPs for me, how they create the actual display image, because the display is binary only, a lot of "human factors" engineering goes on, basically, figure out how to trick the eye into seeing a full colour image. And it works really, really well.
