MiSTer FPGA Forum

Hello,

This is my first post! Recently got a Mister and have been very impressed so far, so much so I went out and got hold of a Phillips Discoverer CRT TV, which looks awesome, but I am having a few issues with getting it working correctly with Mister.

Essentially it uses an RF connection, so I went out an bought a RF to hdmi adaptor. I have managed to get it find the signal on channel 38 on 61.25mhz using PAL I. I am getting sound okay, but the picture is very poor and wobbly with two white bands slowly running down the screen. When I remember back to the old days, usually I would just tune the channel and it would correct the picture. This looks like it is set, and I can't adjust it on the screen.

I used this: https://www.amazon.co.uk/dp/B0B6CYB3ST/

Any advice on troubleshooting?

Thanks,

there should be a fine adjust on the back of the TV, refer to your manual, you might need to fine tune it.

lovely looking crt.. but such a shame phillips didn't put a scart connection on it..

Thanks. That is not an option (I checked the TV manual before posting). It is auto-tuned by, as such the 'control' tune function is disabled (at least by me observation)

I have ordered a RF to RCA adaptor and a RCA to VGA cable, hopefully that will work.

RF is always fuzzy.

I've seen some videos on youtube of people modding TVs by directly wiring composite video input to RF modulator circuit output.

Yeah always loved the look too but Philips had a nasty habit of locking their CRTs to PAL only even as late as 1998 on their Blackline series, ludicrous

i had a 14" portable phillips that i bought brand new in '92 it had a scart socket on it.. (it wasn't the Discoverer model) it only went kaput last year. it had a great picture. was perfect for my amiga 1200.

Ironically, most, if not all PAL Amiga15Khz monitors, were made by Philips, equipped with SCART or other types of analog RGB connectors.
