I have a vizio p502ui-b1e . I noticed a slight dark spot on it the other day. Does anyone know if this is an LED that is out or is it the LED Driver? I have already tried a factory reset.

Its wearing out n will cost as much to fix as new in wal*

Probable power supply failure

This is unfortunately a not uncommon problem that others have told me about and Vizio only advised them to buy another television.

Struck by lightning is highly unlikely.

Test the various power supply voltages if your able if they all look good change the main and see if that fixes it, it should.

Those sets use LED backlights and the lights are driven to max luminosity. The individual LED failures cause the whole unit to cease

After the main board replacement, in most cases, a firmware update is necessary. If you wish to get some details; check the site linked here.
