Q:TVRS Glasgow question ?
All TV repair people have all the power cables they could need. BUT... if they think that your fault could simply be a fault in your cable, then they may take it with them, though they would be more likely to try swapping it on your premises before removing the set.
Q:using a smaller size power cable?
The wire will melt and possibly short out to metal if you pull too much current, which you probably will do with 2400 watts. 10 AWG is only good for 30 amps,
