Good deal.. My last name being Murphy, out of 30+ tv's I think just one had bad caps. Maybe my next 30?!?Comment

Re: Samsung LNT3232HX-XAA
Was that the 10v 2200uF ones that failed on em? I had a job where we had 15 of those units fail at a hotel.. Had to go from room to room repairing them.. Took me almost the entire day having to setup my work table, equipment, etc then re-pack everything to go to the next room.Comment

Yes, 2200/10V for the standby 5V, and 1000/35V for the 24V. I changed all the caps in the secondary side.Never stop learning
