TV clicks, but doesn't turn on, opened it up found a burn resistor at R14700. I replaced the resistor, a 27k 1/2 watt, with a new one and same problem happened. Do you know what is causing the burn out? Got this tv from family and i'm not going to take a free tv to get repaired, i'd rather do it myself anyway.
any help would be appreciated.

If the resistor is found burned; there should be a reason. IC short or some sort of that. Without rectifying the fault; if you replace it with an other resistor; it too will burn out, sometimes cause more fault to set. Check for the reason first. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Thats a 27K 1/2 watt Carbon Composition resistor 5% tolerance. You got deflection issues so a replacement resistor will most likely fail unless you discover whaich componenet on the deflection board caused the resistor to burn. The deflection boards have been discontinued for your model which has the ATC321 chassis. But you can get a remanufactured ATC321 deflection board from www.tvrepairworld.com
i am having the same problem. My Phillips 37" 37PF9431D/37I LCD High Definition TV won;t turn on. When I press the power button i hear a click and the green light comes on for a couple of seconds and then the red light appears. I can;t figure it out. Did you find a solution?
The number you gave for the resistor is incorrect. But I did find a R14705. This resistor is a 1/2W 27K ohm resistor. This part is also in the deflection circuit. This is not a good circuit to play in, and resistor do not burn up by them selfs. There is a problem somewere neir by. The part number for this resistor is 238958.
From your description ..actually this is a common problem and no simpley replacing the resistor will not fix it. this chasis has a problem with what is called the high voltage splitter.. there was a number of these made with a defective splitter. RCA HAS ISSUED a service bulliteen for certain models and serial numbers. the board and the splitter is generally replaced. (I just worked on one of these 2 days ago and got and order in for the parts) ......just reread the tech bulliteen.. the spitter which develops a crack is rca part number 258512 the resistor or the part that burnt is resistor a common 27k 1/2 watt 10% carbon resistor
