Packard Bell 17VT1

After you let it "cook" for a while, if it's still really weak, you can also try running it at, say, 8V for 10 minutes, then put it back down to 6.3 and test it again. Has worked for me. Only time I tried "restore" was on a Trinitron, and it made it much worse, rather than better.
