This is not true. However OP, I’m pretty sure you don’t have the knowledge to fix this kind of damage. I suggest to look for an electronics technician that can help you out. Depending on your budget, it might be cheaper to buy a new one than to pay to get it fixed but if it has sentimental value or it’s just a dumb TV (nowadays that is a feature IMHO)…

Pretty good.
