Hello

Welcome

Firstly I can only deal with your question here not be email so please respond at all times here.

Yes those capacitors you spotted ideally will need to be replaced samsung suffer greatly from bad capacitors the 1000uf one replace with a 16vdc working one so you have upgraded the working voltage and also if possible obtain a 105 degree one (likely there is a 85degree in) the other you may need to take out (hopefully you can solder?) and observe its value and working voltage, its very likely the problem is just this.

Your other option is to replace the complete powerboard however that is $80_$100 compared to about $20 for the caps

You should be able to get the caps from www.mcmelectronics.com or even radio shack if you take them with you

Let me know if you need more help

Sorry i just seen you are in the UK I am myself but also deal with US customers (I am near Warrington) so just to clarify the caps are bad you can get these devices from various sources locally like maplins they cost about £2 each

If you need more help let me know the support is on going
