Question about Toshiba 50H81 50" Rear Projection Television
For at least a month I've had squealing from the back of the set (which I thought was the power strip until this week) when I turned OFF the tv. Now it sometimes makes the noise when the tv is turned ON and waviness occurs in the video (just in time for the Super Bowl and we're in Patriots territory). Any thoughts? The set is around 5 years old.
A leaky crt uummm Jaime may be referring to a leakty eht block... flyback assembly... probably a better work to desribe it. You willl have some very high nd dangerous voltages floating aroung in the back of the set. But by inspecting it under dark conditions, you may be able to see if it is leaking... Check for dry solder joints about the flyback transfomer. BE CAREFUL. High voltages are STILL PRESENT after the power if off in these stages. Taking it to an agent would be a better idea if you are at all unfamilier with how to ADMINISTER CPR TO YOUR SELF
Good luck...peace out

First thing to do is the reset and the whacking test. I give this a 50/50 chance of clearing it up.
ONE: Disconnect the power cord for 4 hours. Then when you power it back up the internal soft codes will automatically reset to factory defaults.
TWO: The whacking test is to just bang or smack the set with your hand on the back, side, top, etc., to see if there are loose connections or cold solder joints inside that are acting up. If so, the banging should knock them back to normal and the set should restore. You might have to use some creative banging and some have had to put a book or magazine under one corner to torque the chassis enough to get it to work reliably.
If these two procedures do nothing then:
