Question about Audio Players & Recorders
Any of the capacitor on the mother board could be blown on the mother board that needs to be checked and replaced if the transistor LM1117 which you told to replace looks ok.
keep us updated.

Yeah that part is the voltage regulator. The problem seems to a power dropout. LM1117T-5 can be replaced if LM1117 in unavailable. You'll just need to double check if that part is already shorted or burnt. Visually check any other faulty electronics component as well on the circuit board for possible replacement.

it Works very well. Easy to install. Good remote control. Good value.
To try to re-solder the board....
MAKE SURE YOU HAVE A LOW WATT SOLDERING IRON AND SMALL SOLDER.
Here's the directions that helped me...Good Luck:
By opening up the radio you will find a narrow display power board
With in the left side of the radio (faceplate toward you). This board
has a metal cover soldered to it, with a toroid (wire wound doughnut)
inside on one side, and a bank of surface mount resistors and
on the bottom side. One end of the board (SCR heat sink) is screwed
the heat sink at the back of the radio, the board is secured with 2
metal bend-tabs, and it has a white mini connector on the other end
which connects to the faceplate. Remove the board from the radio.
On the bottom of the board look for surface mount components
R1057/C1071/R1058/C1083/R1064. The colder these resistor/capacitor
chipsets get, the brighter the display. I left the car out in the +5
degree weather and the display worked until it warmed up a little.
is how I was able to track it down to these temperature sensitive
parts. Freeze-it also helped after I narrowed it down to a few
