I found opened up the Tv and discovered that the power board is smoked. 2 capacitors were bad and on the back of the board were the caps sit are smoked too. Where is a good site to find the replacement board? Should I try to replace the bad capacitors and bad resistor?

yes! replace all the bad components but first isolate the problem before you power on. Also check your bridge rectifier diode and check the power regulator. if all of the said components were okay. you can now proceed checking your P.supply. isolate your power supply do not attach the output line to the main board. then power on. check the power line output. if it is stable. turn off the switch then assemble the p.supply board to the main board. turn on but make visual observation. i hope this can help you..that is the basic rule when troubleshooting p.supply..
