Re: QL Vision monitor has a blank screen.

Re: QL Vision monitor has a blank screen.

Ok Good call for the diagram! I'll print it off. I use Amp Electrical in Nottingham (UK). They help keep my late 1960's French Hi-fi in tip top shape. He's proper old school. He also does Tvs, but I think he should be able to do something. I'll give him a call tomorrow unless anyone can say if there...

QL Vision monitor has a blank screen.

Hi there, As a QL joblot I have a Vision Monitor. It switches on and off, the amber led light works, The screen crackles and has static, but has no picture at all. It just stays black, nothing.

Re: Mono Out Jack

Maybe start with a high resistance on the pot and then turn it down? Therefore less chance of damage?

Re: Voltage Regulator update?

Got it. Pin out is OK. I've done it for species and zx81.
And I will only do the one bolted onto the heatsink and labelled 7805.
Cheers

Re: Voltage Regulator update?

OK Thanks, I have ordered some.
From what I remember seeing, isn't it just a case of unplugging one and replugging in the replacement?

Re: Mono Out Jack

Thanks
The parts are on order!

Voltage Regulator update?

Can I change the voltage regulator for a Traco one like the Spectrum?

If I can, is it the same part as the Spectrum one?

Re: Scart to HDMI upscaler

No, unfortunately I still lose a couple of digits. I have 2 different Rgb cables and both have the same problem.
