Question about Televison & Video
Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

W11NB80 is an N-channel 800V-0.65ohm - 11A - rated Metal Oxide Semiconductor Field Effect Transistor [MOSFET]. You can use the folowing substitutions for it
[ 11NM-80, 12NK-80 & 10NC-802]. All of these are its equalent substitutions.
Before replacing the mosfet, check the entire power supply secion for any short circuit, or zener diodes faults. If any of the zener diodes are fused, it will run out the MOSET you sumstitue again. Check it keenly. Unsolder one end of each component, lifit it up a liile from the circuit board and check. Especially zener diodes must not show any leak in 100Kohms range. It is best to replace them all I suggests.
I don't know about its availability in Keniya, yet you try to get it from any electronic spare part shops. f feels any difficulty in getting the same contact [E-Bay] site, they will reach you the exact component at your doorstep. Ok.
