i have a rca-- rlc3257a lcd tv and when i go to turn it on i get no power what so ever. I checked on you tube but was no help. the capasitors check to be all flat on the tops, so i would like to know who to check the resistance of the capistors and diodes, to see if i have any bad capasitos or diodes. I tried to find a serivce manual for this tv but i not sure where to look, any and all help would be appreciated.
