Transmitter doesn't work

Defective AOMWAY 5.8 1000 mW

The antenna was all the time tied and I hadn't taken it off. After that everything was OK. There was a high-quality picture through the receiver on TV, but there was also a smell of burning from the transmitter. Next day I turned on it to try the video signal at a distance. The transmitter had worked for 15-20 seconds and then turned off, the picture on monitor disappeared and the LED of operation indication went out. At the same time there was a burning smell again and the transmitter became very hot.

Now the transmitter works for 15-20 seconds, becomes very hot and turns off, though the ventilator is OK.

Add 13/03/2015:
By the first turning on my power amplifier SE5004L burnt out ($1.5 for 1 piece). It is under the cover with a ventilator, not far from the connector SMA. It’s impossible to solder the power amplifier by yourself, that’s why I brought it to a mobile phone repair shop. They solder it for $10. Now it is OK.

У меня при первом включении сгорел усилитель SE5004L ($1.5 за 1 штуку). Находится под крышкой с вентилятором недалеко от разъема SMA. Самому перепаять усилитель практически невозможно, поэтому я отдал его в мастерскую по ремонту мобильных телефонов и за 500 рублей и 20 минут времени его перепаяли. Сейчас всё работет.
