Hello there,

i sucessfully renewed an old NEC Multisync II JC-1402 TTL/Analog RGB Monitor (Electrolytic Caps and so on) but my Flyback Transformer (LOPT) is on his last Breathings.
So i have a fuzzy Picture in Warm State at about 20-30 Minutes.

The Service Manual says that this Fault is the Flyback or the CRT. The CRT looks like new, no burnings on the Screen and the Neck is crystal clear. I can get the Picture Sharp and Crisp with Tuning with the Focus Knob. The Focus Pot at the Flyback are straight to the full left Position and at 2-3 Hours the Picture gets little blurrier, so it´s out of Range then.

No Whining, No Whisteling, ...

So the HR-Diemen: HR 48689 is the Replacement for the 47105637 Type of LOPT i have, ... But Flybacks are hard to find nowadays, ...
It will be cool to have a Replacement to see this Monitor live fully Working again.

I´m not a TV Technician but a Hobbyist but i revived some older Monitors without great Problems 😉

Greetings
