Television and Home Theater

  I have a 42" Philips HDTV flat screen, which I purchased about two years ago, new.  I now am experiencing color bleed (yellow) on flesh color.  Is there an adjustment I can do or is there a problem with the TV?

My set started showing nothing but snow so I had a Repair shop fix the set.They came & took the control unit out of the chassis & just my luck they went out of business.Now I am trying to locate the control unit which sits inside of the television.I may not be calling this part by it's correct name so I'll give a brief description.The service tech that I had fix it called the part a circuit board.The part is basically the internal brain of the set and it has the power cord ,and all the rca's attached to it.Any info on this part would be greatly appreciated.

I have a Mitsubishi ws-55511 TV, And for over a week now i can't find whats wrong with it, The green light flashes for about a minute after you unplug it or press the rest button on the front, but after that... the power button on the front or on the TV's remote will not turn the TV on. I know its getting power cause when you unplug it from the back you can hear the TV powering off. But I still have no picture, no sound, no nothing, What can i do? The TV repair guy quoted 95+ just to come take a look at it thats not including parts or labor.....
