Just had geek squad out, guy was very nice but I'm a bit worried. He took a look at it, saw the problem. Said that it "looked like" they'd be able to order a new panel for my VT50, but they wouldn't know for sure until the order was placed. He said when and if the new panel arrives, he can tweak the sustain voltage but he would prefer not to touch it. He said if it turns out that the panel is unavailable, then they'll just give me a replacement.
Guess I'll know sooner or later what they're going to do. Obviously I'd prefer a replacement TV...
