Help please. I’m pretty sure our son left our tv on for several days. Now we get sound but we can only see the picture if we hold a flashlight up to the tv. Is there something we can do to fix this or do we need to send it to a repair shop?

I suspect the backlight for the LCD has issues. But it could be power board too, if you are unsure on how to check, send it down to the repair shop to check.
