Доработка PSU (уменьшение тока LED подсветки) разных моделей TV


Message added by LiVan

Доработка PSU (уменьшение тока подсветки) разных моделей TV.

Пишем подробно,  обязательно с лично снятое фото, как  вы делаете доработку по уменьшению тока подсветки.

В своем сообщении указываем:

1.Модель телевизора

2. Модель PSU

3. Драйвер светодиодной подсветки

4. Участок схемы или фото платы где произведена или требуется доработка.

5. Показание амперметра до и после доработки по ограничению тока подсветки.

Перед публикацией обязательно проверьте нет ли уже точно таких же данных по доработке  PSU (уменьшение тока подсветки)

Если данные в теме уже есть не нужно их дублировать, пишем только если у вас другой способ уменьшить ток подсветки.
