Protron PLTV37C 37-inch LCD TV Yellow light indicator on; no picture or sound. Is it repairable? I was told the company went out of business and no parts are available.


There is a history with the power supplies failing on these TVs if it fails to power up, nut it could also have a back light inverter board defective.
The LCD still repairable if you find a good TV technician that knows how to fix electronics devices to the component level.
Let me know if you need further assistance.
