Just a quick shout of HELP !!!

I have recently had some problems with loss of picture and sound and a total loss with a Ld:20 error message (Samsung smt-2001-c)....

since coming back on the problems seem to be worse, although for the most part everything looks fine, which is annoying for when the engineer comes out ;-) (THIS MONDAY)

Anyway my question is, I have checked in the Engineering pages and on the 'Downstream' page the 'AGC tuner %' is 88 but keeps flashing to 100 and RED.....and the overall 'Combined AGC %' 85 ORANGE.....I'm assuming this is bad ?? Is this the cause and what can an engineer do to correct it??
I have a 10db attenuator/filter on the line, was this an attempt to solve this problem which has got worse?? or the attenuator has gone bad!
Hope somebody can help and explain if this is a problem or not :-)
Thanks all
