Turn off the backlight and sound becomes normal | Probable defect in the inverter lamps or drivers. | To check if tsound is a burnt out or tired bulb, leave only one plug of the 4 bulbs connected and turn it on, if the backlight blinks it is because this bulb is good, so you disconnect this plug and connect the next one to test another bulb, the one that is not blinking is because it is broken. If tsound is a burnt out bulb, one of the alternatives to bypass the protection is to place an LED diode with the anode on pin 1 to ground. If you want to solve the problem without circumventing the protection, it is necessary to replace the burnt out bulb or replace the bulb with a 100pf ~ 180pf x 2kv ceramic capacitor | EC |
