LCD Touch screen responsive for 1 sec only after power depressed

BLU Energy X Plus LCD Touch screen is ONLY responsive for APPROXIMATELY 1 second once the power button is depressed from sleep mode or at power up, then is not responsive at all until process is repeated.

EFFORTS:

1- Tore it down then reassembled...

2- Drained battery to zero, disconnected battery, continued to depress power button to continue draining- did not work...

3- Taped down IC Chip to keep in place...

NOTE: Not sure why or if due to our efforts, but only ONCE, the touch screen was responsive for approximately a minute, and cannot duplicate this.

Please assist if possible; will order an LCD & Digitizer if cannot fix.
