TV Repair Questions? Ask a TV Technician
Model # XXXXX XXXXX 37647. Nothing connected but a cable cord and a old APEX DVD player. Cant tell if dvd is providing picture because I have no idea what channel im on.
Correct no menu no input and yes I can see the dimly lit images with a flashlight.
The problem is that the backlight inverter boards (Slave and master), or the power supply output rail that feeds the inverters has failed.
These are responsible for lighting up the lamps built into the LCD panel.
The power supply output needs to be tested for voltages both under load and no load to determine which board has the fault.
Unfortunately there are no resets or buttons you can press to fix the problem and the set will require service. Average cost for this type of repair is around $200 parts and labor if the inverters are found faulty, or also $200 parts and labor if it's determined the power supply is the culprit. The problem is going to be either one or the other.
