A problemetic T8 15W fluorescent fixture

This instant start fixture from 1999 is used to be a desk lamp, shipped with 2 MABAO T8 15W 6500K bulbs (one spare), however it failed to turn on since 2018 due to two failed capacitors. The fixture has been put aside for few years until I repaired it in 2022.
Now another problem appeared, the lamp will not turn on when installed in normal way, because of the poor connection in one of the bulb sockets. It needs to be turned a few degrees in order to build a proper connection between the bulb and socket.

Электронный балласт решил стать электромагнитным

Actally also for me when it was powered on for very first time in 2000. It blinked a lot before stablizing.
