Hi, I just recently had the capacitors replaced in my 4 year-old Samsung LNT 4671FX (had the known flickering/power-on problems), done professionally by a repairman. After I powered it on however, I noticed that the physical buttons the side of the TV (control power, volume, channel, etc) and the remote did nothing. Basically I would have to physically plug the TV in and out of the socket (which I do NOT want to do) to get it to turn on/off. Can anyone point me to resolving this issue? I'm capable of working with electronics so a little DIY won't be a problem, I just hope it isn't a big issue as I'm finally glad to have a working TV again (sort of).
