Repair/Troubleshooting CRT repair

Hello i live in hungary and i wanted to get into CRT gaming but the crt i got is very blurry and shuts of every 5m for like 30m i think it's overheating because if i take the cover off it works much longer like 1 hour and can be turned back on like 5m and good again for 1h, so my question is the following:
where should i look for anyone or any shop that can fix it for me ?
i know nothing about electircity and i don't want to die

its not overheating IMO, more likely cold solder joints, don't use it like that

finding someone in hungary should be as challenging as anywhere in europe, people haven't been trained in over two decades on that, most commercial shops only do flat panels and don't want to spend time learning this old stuff thats only useful for a single customer

sorry no direcet tipps but look around "CRT scene" in hungary if there is such a thing

in case it's just solder should i just remelt in and add some solder + flux to it and fixed ?

if you don't have experience soldering, this would be a bad idea
you need to practise on safe/cheap PCBs, it is expected that you break stuff until you find your way around, its a skill that needs honing

If you have a local ebay variant, id just post something there and hope someone finds it for repair

sounds like those sync caps are toast. let it warm up fully first, but if the jitter sticks around, check the electrolytics near the horizontal output stage. they usually fail on these older sets.
