Samsung TV not turning on

Hi, wondering if anyone might be able help.

i have a Samsung series 4 plasma tv, quite old now I guess around 10 years. When turned on the normal red light appears which shows it’s recieving a signal from the remote controller.

but the Tv does not start, there is a clicking sound like it’s going through the motions and that sound keeps repeating but it does not start.

i’m not even sure if parts can be found or indeed if it’s cost effective to try and mend…any thoughts greatly appreciate.

@toby1russell you will have to to take the back off your TV. Take a look at all the boards and check for obvious damage. 在已经存在的问题里加入图片 Post some good pictures of all of your boards with your question so that we can see what you see. You'll need a multimeter to measure some parts once we can see your boards.

Impossible to say what’s wrong, but bad electrolytic capacitors are a common problem, are cheap to replace, and not hard with basic soldering skills. First search the web for a disassembly guide or video, and if you can’t find one, just remove screws from the back until it comes off. (Make a note of where they come from if there are several sizes). Bad caps are often easily spotted if they have domed tops or showing signs of leakage, but they may still be bad if they look good. Take a look at https://wiki.restarters.net/Basic_electr... for more details.
