mp116 ima manu ...
"Published on Dec 13, 2015
This a solution for a problem with the RLC3210 TV from RCA with the MEDMEET MP116 PSU board.
The backlight of the TV will turn off randomly but there is still sound.
All inverter transformer outputs read about 1kOhm in this case (needs to be verified first), all capacitors on the PSU have been checked, the resonant controller L6599D has been replaced, to no avail. The chip detects an overcurrent condition and shuts down even though there is no overcurrent. The solution consists in increasing the current limit which is done by decreasing the value of a 100pF capacitor (c36) on the PSU board. It has been changed to 50pF in this case."

Očito je i proizvođač uvidio grešku, jer tog bloka na novim verzijama niti nema.
