Well LTRG is responsible mainly for charging...u can find it near the sim carrier.Its a 6 pin IC and LTRG is writtin on it.

Too easy to solve this prolem:
- This happen because short circuit (miss spell)
- Use VOM at RX1 to check which Volt supply (EX: Vref) from power IC to be shorted ( Check between two pole of filter capacitor)
- Supply extra power (The same level as Vref) to that Vref
- Touch by hand, check if any hot component
If u see that OK, please send me by email
