I've got a Grundig TV as described in the post title.
Just recently the picture has been flicking off and on until last
Sunday the TV refused to switch on from Standby.
When I push the main ON button the TV emits a brief crackle from the
speakers and goes to Standby without displaying a picture. If I try to
operate the TV via the remote or the panel buttons the LED turns
briefly green and then back to red. I can get nothing more Sad

The Chassis on my TV is a CUC 2058.
If anyone has any info on this model or any other insight into what
the problem is I'd much
appreciate it.

Regards.

As much as I have Experience with TV Sets, I would look for cold soldering points first, which could have caused the flickering at first, maybe because of that something in the horizontal deflection died. There should be a rather large diode on the secondary side of the power transformer leading to a rather large transistor near the line transformer which could both have shortcut (excuse my English).
These are defect by lots of TVs, at least the ones I had to fix...
