Thanks in advance, Hazen Bannister </BLOCKQUOTE> Welcome to the world of growing action brackets. This has been discussed a number of times over the last couple of years. I was one of the last ones with this problem. You need to contact Young Chang, give them the model and serial number, and they will send you out a new set of action brackets, and they will pay you to put them in. Wim  </HTML>
