Could not find any thing for TBA M828. The only LM828 came up when search for TBA M828 as Vague has suggested above.
LM828 has five pins and it function is “CMOS charge-pump voltage converter inverts“. I can not see the whole PCB of your so here is my guess.
Since the SOT-23 laid close to a connector and I guest that is gLCD display connector (right/wrong ??). It does make sense that the LM828 could be used to convert +Voltage to –Voltage for the display. But it is FIVE pins so it may not be right.
More information on the PCB that could help to try to find a solution for the burning SOT-23. Such as picture of complete PCB, try to draw a schematic of that portion of the M828 and the surrounding components (this could find out 5 pins used or 6 pins used).
Here is a link to the data sheet:http://www.national.com/ds/LM/LM828.pdf

ADM8828: Switched-Capacitor Voltage Inverter with Shutdown
Here is a link to ADM8828:http://www.analog.com/en/power-management/switched-capacitor-converters/adm8828/products/product.html
The ADM8828 has SIX pins; pin 5 is a shutdown pin. This could be a compatible device to the M828.
Please take a look and post what you find.
