I have noticed yellowish/pink tints on only parts of the video and even if I have reconnected the hookups the spots still remain in the same place on the screen. Please let me know what this could be for I fear being ripped off by a technician.

Re: yellowish/pink tint on parts of the video
This is a contaminated light engine, this TV is notorious for this. A techniciian who is familiar with this tv can TRY to clean it with canned air and a tiny brush. Panasonic even has a part number for it (basically a water color paint brush). The disassembly and procedure is involved and the results are mixed. If it can not be cleaned the only option is to replace the engine which is not cost effective. It will probably cost you a couple hundred to have the cleaning procedure done but some technicians will be hesitant because it is a lot of work and if it does not solve the problem most people will not want to pay the labor for little or no results. Good Luck

My 43fdx20b had a pink tint to it also. The picture was clear otherwise. I found, on mine, I needed to adjust the Red Screen control. It was located behind the front panel. I removed the two screws on either side of the front panel and was able to remove the panel. Then I adjusted the Red Screen control. I found that if I tuned in an old Black and white movie I could adjust the color fairly accurately. Good Luck.
Unfortunately if you have tried a different machine (it could be a bad video card) and tried the cables most likely it is the screen itself. Typically when one of these lcd's begin to fail the pixles no longer access the blue field and you see mostly red instead of the other two colors. In short pink screen is terminal, it will last for a while longer.
