Hello,

If I remember correctly, the first generation Trinitrons used a vacuum tube EHT rectifier, the only other "hollow-state" device along with the CRT. Maybe your rectifier can't keep up with the current demand and the picture "blooms", i.e. defocuses as brightness goes up.

Please check for the presence of this tube and eventually replace it.

Good luck with bringing this nice TV back to life,

Best Regards
