Chosen Solution
I have a Samsung plasma TV, model number: PS51D450A2W. It just stopped working a while ago, no power on/standby light was coming on. A sparky checked the original lead and said there’s power in the plug, but it’s not travelling up the cable. I’ve just plugged in a brand new power cable and nothing’s changed; no lights, no activity whatsoever! Any advice on what I can do to get this working would be greatly appreciated! My tech knowledge is very limited, but I’ll try and follow any advice given :)
It is very unlikely to have a power cord fail. Since you report that there is no standby light either, than I would suspect a rather catastrophic failure of the power supply board. In order to try to find the cause, I would like to request that you post pictures of the boards inside the set. Remove the back and take photos of the boards. This may be a simple repair or not. Let start with a visual examination first. After that we’ll work on taking voltage measurements. Dan
Could be as simple as a blown fuse in the TV.
