Not at my shop but a quick question. Is that the unit with the large
digital can that costs over 1000? If it is you will find a small stand up
board in that digital package. Remove the stand up board if you have one,
it contains the eeprom. The set will still turn on without it, but if it
has failed it will put the set into shutdown. Just an easy check I like to
let others know about it simply plugs in and pulls right out. Hope this
helps. Terry
