Remote control not powering on! Help me please!

[DroneFisherMan]

Hi All,

I am super new to modding and I am in big trouble with my new drone... lol

i am using bayangtoys X16 GPS drone.
I managed to solder the "alfa APA-M04 7 dBi gain RP-SMA directional panel antenna Wi-Fi" on the board, and it was working absolutely fine. Until, I put hot glue on the antenna's solder to make it more solid.

Since then , when I power on the remote the red light comes on for a second and beeps then it goes off. I removed the hot glue and still its doing same thing..

Have I burnt the Tx?

I have checked for any short on the antenna's ground and main wire, there is no short there. I have checked the battery and power, and all looks good.

the power does come up but then goes away, if I immediately power it off and power back on, then there is no LED,

However, if I pause for 5-10 seconds the intensity of LED is high, and subsequently low if powered on during less intervals.
Could anyone help me out please!
