привет! Greetings from Hungary. Sorry i need to write in english cos my Russian skills are way to low atm. : D

Is there a B and W Zeppelin air veteran here?
Its did not turn on. I replaced the psu caps and then its started, but its only working for 5 to 10 minutes, than its shut down or restart. (Sometimes shut down and never turn on again)

Can you give me any advice, where i start? Its a common problem i think. Some soldering gave up maybe on the motherboard?

Спасибо!

Спасибо. Мы были там тысячи лет назад с некоторыми скифами. Климат в Карпатском бассейне для меня лучше. : D

Good photo's of cover with marking label and both sides of all PCB's ?

Thanks for the help!
They all looks good. Sadly there are no burned components. I hope these pics will fine.

U7 on photo https://ibb.co/vxSRpZW was replacement by you ?
The boards could vibrate to the beat with loud sounds. Therefore, check with a magnifying glass if some solders are broken.

Nope U7 was there like that when i "arrived". I only replaced capacitors.
Yes, i suspected that too. After the change of the caps i tested with high bass music with almost full volume and its worked. After 5-10 minutes its turn off if the volume high or low too.Спасибо за помощь!
I think its heat related problem. I inspected that two board with m.scope and sadly everything looked good. : /
In the end i'll resolder everything (too)..

(For the twist i got another zeppelin today with burned transistors on PSU and MOBO too, so i can't do a swap for test.. : D)

большое спасибо вам!

Oh my god.. Someone brought in a third Zeppelin today. At the moment we do a cross swap test. Its look a like i managed to repair the first PSU ant there are some problem with the main motherboard. (10-15min reset)

I'll report back shortly.

Try my best with this : )
Боже мой! Кто-то сегодня привел третьего оратора. На данный момент мы проводим перекрестный своп-тест. Похоже, мне удалось отремонтировать первый блок питания и возникли проблемы с основной материнской платой. (Сброс 10-15 минут)

Я сообщу в ближайшее время.

YES!

I inspected the motherboard very closely. There was a bad soldering point! Its working now. Two more left.

ДА!

Я очень внимательно осмотрел материнскую плату. Была плохая точка пайки! Теперь работает. Еще два осталось.
