I've tried a few tvs.. even tried soldering a cable direct to the filters I was thinking the composite signal is to weak hence why the picture is poor on rf as it is fed from the composite and on composite it says no signal. I have changed the caps on the composite video circuit still the same.. its really annoying as I know the jaguar is loading games ect.

Managed to get it a bit clearer on rf. Still nothing on composite.. do you think the video encoder is caput.. I've reflowed the legs anyone here have a spare encoder or know where I can get one.. cheers.. 20230509_210814.mp4

Green.. I have tried tuning it different countries made no difference.. I solderd the composite video lead to the board and no output on av.. but the machine is deffo running.. I will change the cap that the composite video signal runs through to the rf modulator..

OK so update. I reflowed some more parts cleaned.. ext.. I can now sort of see it running on rf. Still no signal on the composite lead I bought of ebay. Will solder a lead directly I can solder of the rf as there should be a composite signal there to test. 20230503_173817.mp4

Thanks for the info. Will lift the bios chip and replace it.. and check the traces under it.. I will keep working on it can't let it beat me. Shame they so rare to get hold of for parts.. do you by anyway know whee to get the joystick ports from.. I Seen.blur but not black..

Sorry I have a game plugged in and a genuine psu.. light is nice and bright..

First of all Hi to everyone, Im new here but run a YouTube channel repairing my old retro stuff amigas Atari 2600 just done the cleancomp mod love it. I now need your help, Hoping someone has some pointers for me here. I have a Atari Jaguar that fails to display on either RF or Composite video says no signal or no channel found. All the chips are warm voltages seem fine at u38. I've cleaned and reflowed the Cartridge slot and bios. Next I was thinking of removing the bios and replacing it what you think.. I have a scope but its not really up for testing the jaguar Anyone know of any other problems that could help. Cheers in advance
