BuckoA51.Hi,
I finished the component mod on the speccy but I don’t get a picture on TV.
Composite on the speccy still gives a picture, so the computer is working.
I tested all the connections from the Ula to the component board, every connection arrives there.
What else can I test?
Check that the trrs breakout cable is fully seated. Connect the green component video cable to composite on your monitor and see if you at least get a fuzzy black and white picture.
TRRS is fully seated.
I get no picture at all by connecting the green cable, TV says there is no signal.
Same on a second TV.
Please use a photo or file sharing site and post pictures of your install.
Are the jumpers set correctly for the right output frequency
I tried out all the options with the jumpers.
Silly question but have you flashed the current firmware ?
I didn’t flash the current firmware, don’t know how to do that.
I purchased the board recently, so I expect it to be up to date.
Anyway, I think it should at least output a picture without flashing first.
Please try flashing the latest firmware and let us know.
I cannot find info about what I need to flash the latest firmware.
Can you give me some advice about what I need and a little guide?
Thanks
Firmware can be found here – https://github.com/c0pperdragon/ZX-Spectrum-Component-Video/releases/tag/1.0
There’s a little guide here if you’ve not used JTAG programmers before – https://videogameperfection.com/forums/topic/anyone-ever-attempt-firmware-upgrade/

Hi,
after 2 years of inactivity, I decided to get on this problem again.
I advanced to the Firmware Flashing step, but it stops at 4% each time I try.
I used the Quartus Prime Lite Edition 22.1 with an Altera USB Blaster.
Erasing, examing, blank check is working and advances to 100%
Programing stops at 4%.
Is there an additional step to do for programing?
What else can I try?
Thanks for your help.
Is it a genuine USB blaster or a clone one?
It’s a clone USB Blaster
