I have a generic rf modulator, that is now stuck in ‘test card’ mode. Ie black screen with two vertical white lines, like you'd find on a VCR.

See pics below, the modulator is capable of PAL/SECAM B/G/H/I/D/K and NTSC M, to select - you press the channel +/- button together on the base and cycle between the sound carriers ie 4.5, 5.5, 6.0 and 6.5. You then switch it on and off to commit the setting. That bit i get..

I have tried every possible key press including powering on with buttons pressed etc but it resolutely refuses to show a picture and remains stuck on the test card.

The polish instructions say the same as the English (according to google translate), neither mention the testcard. Any ideas?

Many thanks

Patrick
