I posted a reply here and it vapourised. Then it wouldnt let me add a
lengthy reply to another post, what is usenet up to?
Find out from the customer if he saw a lamp timer warning before this
happened. If so u need to find the lamp timer reset sequence of key
presses at power up (from the op manual). Do NOT send the set back
with the old lamp after resetting timer, it will implode liberating
noxious gasses.
