pulsing psu bush

(1/1)

electrochris:
hi all got a bush 27tv006 with pulsing psu, screen pulsing on and off,fitted repair kit, any help would be great thanks

electrochris:
Hi was just goin through psu , just had a thought, part of the kit has 2 zeners 12v, 24v if by some reason i have replaced the zener in the wrong order ie  12v instead of 24v would this cause the psu to pulse and cause the pic to switch on and off,  its the only thing i can think of. its not like me to make a mistake, but these things happen from time to time 

electrochris:
Hi all, should have wrote 2.4 not 24v anyway havnt mixed them up, still got tv pulsing, think iam gonna leave this one, for a another day its slowing me down, dam thing . anyway if any one has come across this fault please put me in the right direction, many thank again
