First the power supply had some problems. It took long time to power on. And at the same time Buttons on the TV(syncmaster don't work. If the button, such as power on button, is pressed, 'keys locked' appears on the screen. The TV just can be operated by remote controllor, the remote controllor can access all options of seting. Today I took the TV to a repairing store to ask the staff to replace the capacitors which are pointed in the solution in your wibesite. Then the power supply works But the buttons on the TV still don't work and also some options can't be accessed by remote controllor. could you help me to get some solutio? Tanks

Set TV to standby and press Info, menu, mute then power. The set should turn on with the service menu available scroll down until you select reset press right hand arrow next to enter and then enter. TV will turn off. When switched on it goes into Plug and Play mode to reset the analogue and digital tuner. Allow a full reset then you should be ok.

Hi, I have just had same problem and rang Samsung who sorted it ! All that was required was to reset remote by taking out the batteries then press power for approx 10 seconds and then replace the batteries and hey presto it worked!

This is the best solution for your problem as a 40 year experience with wires etc. Go to the source of your cable signal connector . Open it and clean the terminals with emery paper , sand the end of the cable shiny clean from corrosion , get a new barrel connectors with gold terminals if possible lengthen the ends of the cable , insert and tighten good, use thick rg-16 or rg 40 cable with good insulation ends crimped professionally with a crimpier or buy ready made , not from dollar store. Get a gold plated professional splitter if you need one or two , it will cost about 15 or more each . Make the cable runs as short as possible, using the thick good cables. If needed get a signal magnifier. From radio shack or the source etc. Connect them good and tight . Ground the splitters . Problem solved , you will get crystal clear channel 2 to 7 including 3 and 4 . Isolate the TV cable from other cables and power wires. Vitally

what was the need to replace capacitors. if so on which circuit? Hope you have replaced the right value and type of the capacitor. Observe whether soldered points getting into other pcb track. Clean them again and give a try.
Press UP & DOWN buttons together on tv's
local control and then switch on. You will see
SERVICE MODE. Do not press any button,
just power off the set, then on.
