UPS BE500R-PH microcontroller pic16f716

No, the PIC16F716 microcontroller does not need to be programmed before using it in a UPS. However, it is recommended that you program the microcontroller to optimize its performance for your specific UPS.

There is an available schematic diagram for the APC UPS BE500R-PH. This diagram can be found in the "APC UPS BE500R-PH User Manual".
Check it here: Back-UPS ES BE500R User guide ' Schneider Electric (apc.com)

The most efficient way to use a UPS for a home computer is to connect the UPS to the computer's power supply unit (PSU). This will ensure that the UPS provides power to the computer in the event of a power outage.

Finding a Microcontroller for a Technics Tape Deck

I am sure there is one available or suitable sub . I wonder if technics would provide more information if you contacted them or a local electronics store.
A microcontroller may or may not be programmed for a specific purpose so, that also may be an issue if not purchesd froma source used for that device.

There is also a forum called tapeheads:

Technics RS-B49R - Tapeheads Tape, Audio and Music Forums

I already replaced the power supply now the green light comes on but there is no picture or sound and it dont responed to the remote

You must go on fromthe point you left off, trace the +B to the circuits, check the microcontroller, the sub processors, confg of the ic's can be got from manufacturer's site. Probe only if your are familiar with these sensitive circuit, have a rough idea of the LCD TV circuit. Look out for any fusible resistors to the main board replace or ceck PD across, if showing low ther could be failure of PCB ....you may be infor an expensive work... Hope this helps

Tv shuts off after 10-20 minutes

its not the problem with ur electron gun tube or with any picture ic or sound ic. Every t.v. is microcontoller switched machine.
any damage to microcontroller ic that controls the switching will lead to this kind of problem.
0.01% chance of residue EHT voltage would have affected the microcontroller.
