If your Westinghouse `VR-3215` LCD HDTV has sound but no picture, the issue likely stems from the mainboard rather than the backlight inverter. In cases like this, replacing the mainboard is usually the best solution.
The mainboard is responsible for processing the video signals, and if it’s malfunctioning, you won’t get any picture even though the sound is working fine. You can find a replacement mainboard through various electronics retailers or online marketplaces. Just make sure to check that the part is compatible with your specific model to avoid any further issues.
Once you have the new mainboard, replacing it typically involves opening up the TV, disconnecting the old board, and connecting the new one. If you're comfortable with DIY repairs, this can be a straightforward fix. However, if you're not familiar with electronics or don’t feel confident doing it yourself, it might be worth considering professional repair services.
