You might want to check your cable box settings first. Sometimes the remotes have a picture size button on them, and the in-laws could have pressed that by accident.
I have a new Samsing LCD TV. All was great, with full size picture available through my satellite receiver. Until that is the in-laws came to visit, and after returning from work I found that I now no longer have a full size picture available. I can get the 16:9 ratio only which leaves me with left and right black envelopes either side and a reduced picture size.
I have tried everything in the manual to adjust this, but I cant get there. The Just Scan option is not available (not sure if this is an issue).
I am really frustrated becasue everything has been working perfectly up to now - those pesky in laws.
Can anyone suggest a fix.
