Grundig CUC120 CRT TV

[neuron]

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

Thank you for your comments, info.

Works




Brightness and Colour Pot.: Min -> Max OK

Contrast Pot.: Min -> middle ok

But I can' rise
If I push this Pot. the image:
large ...
no FOCUS and
washed out -> I only see a Blank RASTER.



Note: This Model and CUC220, CUC720 almost identical



Thank you,

Ruy
