you could try running it through a VCR first if you still have one. Other than that and making sure all your contacts are clean, maybe try a different rf cable.
Unfortunately the PAL UK 7800's do have horrible rf output, thats why I have video modded or bought French systems.
The 7800 is a great system with some awesome titles, especially the home brew stuff. Just a shame the video looks so bad


Are there different verions of RF leads or do you mean just an alternative to the one i'm trying at present?

I would certainly try a CRT, I have recently dug up an old 14" Sony CRT for my games room and it is so much better playing old consoles on this than a 19" LCD.
In my experience though, most PAL 7800's give a fuzzy picture, so glad I got my hands on a French RGB Scart 7800, it looks even better than my s-video moded PAL and NTSC 7800's. But even this french console had problems with my LCD, would not work at all with the original Scart lead but worked ok'ish with my STe scart lead, problem was a blue block of colour like an overlay, about 2"deep running across the LCD display:?

Do you have any 7800 carts to test it with? Do all your 2600 carts work fine? What do you mean by "terrible"? Do you mean bad colours? Sync problems? Fuzzy picture?

always good to see another Brit on the forums, hope you enjoy your stay.
@ GroovyBee, nice guide:thumbsup:

Connect the 7800 to its joystick (left hand port), RF lead and power block and try this :-

1) Connect the 7800's RF lead directly to the TV.

2) Press the 7800's POWER switch so that the green LED next to it (on the right) is illuminated.

3) Select manual tuning for a vacant channel on the TV's remote.

4) Set the TV reception signal type to :-

PAL-I

The "I" might be in the sound part of the tuning menu.

5) Set the channel to :-

CH36 or 591 MHz

These are the same TV channel.

6) Store the changes for the TV remote's channel.

7) You should see the Asteroids game playing.

If :-

i) Game appears in black and white - Fine tune the TV channel
ii) Game looks slightly fuzzy - Leave the 7800 powered on for 20 minutes or so and then fine tune it again.
iii) TV shows the blue screen (i.e. no signal) - Reselect the channel on the remote.

There is no sound in Asteroid's attract mode until you start playing it.
