I have a Akai plasma pdp4295ed This was a non working tv when i picked it up ,upon opening the back panel up i noticed that all the big caps on the power supply were buldging and showing signs of being bad so i replaced them all . I went ahead and powered up the tv and every thing looked ok ,The menu came up with a blue back round and the tv started searching for a signal. I did not have anything hooked up to the tv so i shut it down and grabbed a dvd player which i hooked up thru the componets 1 input after powering the tv on it looked great a perfect picture great color nice and sharp. I was thinking that went way to easy and i was right. I shut down the tv and hooked up the cable to it after powering it up again it searched for a input source and found the cable. The picture came up but it was in black and white no color at all when input was the cable so i switch back to the componet 1 the dvd player ,and once again a perfect picture color was working fine. switch back to cable input and the picture goes to black and white . Anybody have any ideas what would cause this or what board i should look at. thanks for your help
