Dark picture on the right side/ backlight lighting but without powerPFC power supply was not bending only 167vIn this case tsound were altered resistors (100ohm less than it should) in the resistor bank that picks up the CP8035 capacitor (450V), more specifically RB803-806 and RP809-812 Remove and measure outside PCBmicropcb

After repairing the power supply, normal alloy, after a few minutes it starts with infinite loop. Soon it, it turns off. Sometimes it calls normal, it works a few minutes and goes back to the loop.Check the main power supply capacitor (100UF X450V). Good appearance, only it gets a lot of heat.replace 100UF X450V capacitor at the power supply.Arock

Does not turn on, triggers protection, LED standby accusing 2x error (screen error)In this case be aware that the defect was on the main plate.SMD Capacitor shortly close to the TCC and CI processor to the A4801A also damaged in the TCC circuit - components are under the sink.rafaelmoraes99
