    Ha ha! I recognize “Forbidden Forest” as the final screen shot! Classic!

    Nice job,i had a C= 1960 multisync that a guy ran till it burned the hot to a crisp. burned a hole in the board and the transistor crumbled to dust when i touched it. Its amazing what they survive.

    10:19 that black capacitor next to the 5w resistor is bulged

    I just fixed my 1902A it had some bad solder connection on the flyback, while I had it open I installed a RGB mod I found in an old forum, after it soldered all the wires in noticed there is a socket on the main board for a scart connector but I cant find any info about it ? I see your board also has a scart socket to the right of the din connectors, it looks similar to the 1084

      Well done. I'll have to look into that RGB mod. Would be nice to be able to use it with the amiga although I dont own one at the moment :(

    Did you fix the traces with lead? Wouldn't been better to jump cables instead?

      Yes thank you. I laid a bare wire over each crack before soldering over the crack. thanks I forgot to mention that.

    I have a 1902a monitor and when I turn it on and plug up my Commodore 64 to it and everything thing is on I get no picture I have turned the nobs and pushed some buttons but no matter what I do I still get no picture on screen and idk what could be wrong with it any help would be appreciated

      If you dont hear or feel the crackle of the static on the screen then you probably have cracked solder joints around the flyback transformer. It could also be one of the raised up resistors on the board those also fail.
