I have a Hitachi 43FDX01B that was handed down by my parents after they got a new TV. Lately it has been flickering with a reddish-purplish tint after watching it for a while. It's fine for about an hour or so, but after that, it starts to flicker those tints. One time it actually stayed with a purple tint for a good amount of time before going back to the normal color. What could be causing this? Can it be fixed and is it worth getting fixed depending on how much it will cost? Is it something that I can fix myself? I recently moved the TV about 50 miles away from my parents house to mine. I'm not sure if the move could have caused the problem or not. It didn't start flickering right after I moved it though. It was fine for about two or three weeks. Any help on this would be appreciated. Thanks.

According to the system the problem in your projection is convergence and the solution is to replace the IC STK's.The part Number is CZ01341. Change the IC STK both and your TV work fine again.And for parts please see the link below.
Make sure your component cables are fully seated in the TV jacks, and also in the source (cable box, dvd, etc). Sound's like you are missing the green signal.
This actually happened to me and I spent an hour figuring it out.
Sounds like you're blessed to have a tv like that!
Some sets have settings that will cut down the sound during a commercial. Haveyou looked at your owner's manual? This tv may have setting to cut out the picture also when commercials come on.
From a technical view point generally commercials have stronger signals than regular programming. This may be overloading your set.
If this is the case, then you need to have it checked by good technician. A poorly operating power supply (not regulating properly) could possibly cause a problem like this. Also automatic gain control circuits could be not working properly.
