i didnt see the country flags

i life near kaiserslautern rheinland-pfalz.
i think i will stay away with my oscilloscope from the tv. i will train me on lower volt equitment first! and i have no isolation transformer
i will search for some spare caps, when i find something i will post it. so the only things that are importent is V uF and ESR. i will search for this over 100°C caps. i already read that i can go a little higher with V.
deflection grid, what is this in german? i think the picture was square befor i started working on it but i didnt look for it.. so i will get the leaking cap new and then we will see.
befor the pictures i cleaned the board with a vacuum, no liquids. the caps are a bit apart and there are other caps in between with no marks. the color looked the same(the small one had more gung so the colour was darker). on the underside of the pcb i found some black stuff(cap juice?)
i found other caps with "colored" legs but there was nothing to see if something had leaked.
i thought the same about the flicker, maybe it was this way. but it got away after 10mins and i used the program list of the tv, this shouldnt be an interlaced screen?!
yes the service manual tells me the points, i searched the schematics but couldnt find them. i think i have to look again. the system voltage should be in the psu area?
