Filled Atari SC1224 CRT Monitor Repair

[Jester]

I have an Atari SC1224 Colour CRT monitor that is dead and won't power on.

I'm opening this request to ask for the services of @roy_bates as he is local to me.

Roy, I'd very much appreciate your assistance.

Thanks

i gave it a bit of a look over ,it looks like i will probably be able to fix it
itll just take a while,and it needs a clean

 

[roy_bates]

parts are on order,lets see if i can get this working

 

[roy_bates]

this is now repaired i think
power supply was dead,so replaced the str-41090 and ktc2120 (2sc2120y) cleaned it up and sorted out the cold solder joints everywhere
after i seen it up and running i noticed the pincusion control didnt do anything and was badly barrelled,turned out to be a bad transistor a 2sc1815

here are some pictures to look at and show it works,one extra one with the back off,some of you like to see the guts of monitors

ill go send him a pm and let him know
