ремонт ADSL модем D-Link DSL-2640U после грозы

отдал мне знакомый аппарат, гроза прошла через eth порт и убила девайс.

хочу сделать себе из него точку доступа.

 

симптомы: при включении загорается питание красным. и 1 раз мигает status.

в консоли апп ребутится в цикле.

дико греется свич. градусов под 70 наверное.

не работают 1 и 2 порты. 3 и 4 работаеют. пинги ходят через раз.

но в режиме СFЕ пинги ходят стабильно.

откинул свичу ноги до трансформатора от 1,2 портов, подумал что через них он греется (через подтяжку трансф. к avdd), не помогло.

греется из-за чего-то другого.

есть схема на асус wl-500g, но там откровенно ничего не видно из-за качества :(

пока не могу найти пинаут на него.

чтобы полностью откинуть питание с аналоговой части 1-2 портов.

напряжения 1.8 и 3.3 не занижены.

попробовал прошить через морду.

и т.д. тело впадает в ребут.

подскажите пожалуйста как подробнее узнать что именно не проходит в тестах и почему оно ребутится?

может специальную прошивку залить, чтобы детализированный лог был?

может проц уже окончательно труп и не стоит разбираться даже со свичём?
