Sony KV-28CL10U Dead Can't Post

Hello group, any advice apprecaited to a retired old school electronics engineer appreciated. My Sony KV-28CL10U has eventually give up the ghost, its been the worst TV I've ever had. In only three years I've replaced the LOPT and had to varnish the EW coil, well tonight it went pop and left me with the dreaded blinking LED conundrum. I used to subscribe to euras but that was many moons ago and would appreciate any areas I should be looking, the LED is blinking 11 times with no indication of any HT.
Regards
Otto, the skip ratcher.Crazy

check the horizontal o/p transistor for short circuit.if not lift the collector pin and check for 120v approx on the collector point on the pcb.if voltage is there then the flyback transformer(loptx) is probably croaked.repost if no luck.
