Title: Does anyone repair CRT rejuvenators?
Post by: timply on May 08, 2018, 02:05:48 pm

I bought a Sencore CR70 a few years ago and it has never worked. The power light comes on but there is no neck glow when its hooked up to the monitor and the gauge doesn't move at all.

the power regulation for the filament in the sencore is (for what it does) quite complicated.

Given the large number of switches and adjustments, there's still the possibility of user error.

Check over everything one more time before giving up.
