Hi,

I have CRT TV to repair:

elektrotanya.com/grundig_cuc120.pdf/download.html


The screen is black ... and we notice from time to time (when
the image is very brig.) some small part of image.
Very few dots.

I tested the G1, G2, Heather, Power Suply ...

Can you please provide help?

Thank you,

Ruy
