Unplug the set and take the back off,by removing the phillips screws.Follow the mains lead to the main board. Check the small glass fuse,if the fuse is intact then I suggest you stop your investigation. To carry on you will need testing equipment,to check the primary, and secondary circuits, and the LOP TX. Don't be tempted to remove any leads/connectors,especially the red flyback lead at top centre of the crt. Repairing the set will not be cost effective. If you are handy with a soldering iron and are familiar with metering electronic components,then a service manual is easily obtained from the internet. Although the set appears to be dead,the crt may still be charged,and so will the large capacitors on the board,so be careful.
