Lopt

What would be a suitable check for intl diodes diode-split device? No reading on tester at eht outlet(transformer out of cct). Should be about 30V if OK. Primary seems to be ringing as viewed on 'scope.

In my experienec there's no easy check for a shorted diode other than replacing the transformer.

I assume the LOPT was deemed faulty when in the TV?

What TV is it out of? That might help. For example the old Thorn 1691 mono portable was able to be repaired by the addition of a series diode following the internal shorted component - a common repair back in the day. Of course in a large screen colour set that's not an option.

Yes, doubt if these are obtainable now. From a Toshiba 28n 03b. Looks like end of the road but I'll keep the chassis for spares, if anyone wants some. Tube was OK.

Always worth trying HR Diemen - they still hold some stock for older items.
