check for fly back transformer
but remember that before you replace any thing in eht section check for power supply output to be ok.
also check for diodes,capacitor connected to flyback transfomer.
also check for mica sheet is not cracked or h/output is not touching to chassis.

switch mode power supply? it has a in or primary side and out the secondary side of a switch mode transformer.
check the driver IC that runs Q102 it makes a oscillation that Q102 amplifies. now the secondary if has a short will blow the Q102 look for shorted rectifiers in the secondary and fuse resistors that are open, even go far downstream and check the HOT for short.

The service person who told you so is correct. EF series LOTs are of old National Kit, and is not available now. If you have a chance to get it from somewhere, it will cost more that RS 800/= ie about $18, and with that money you can purchase a new kit for your TV, provided your TVs picture tube is good. Just do as you like in this case. Todays TV kits are assemled and aligned, comes with more than 250 channels and includes all accecories, like remote handet, fitting material and so on. OK.
