My TV is showing captions that are
misspelled.
You are watching a live broadcast and spelling errors made by the closed
captioning production company pass through uncorrected. A prerecorded
program will not show any misspelled words because of the normal time
available for editing the captions.
My TV will not show the text in its entirety
or there is a delay of what is being said.
My caption are scrambled with white boxes
on the screen.
My program guide listed a TV show as being
closed captioned, but none of the captions
were displayed.
My TV screen show a black box on
certain channels.
Captions that are delayed a few seconds behind the actual dialogue are
common for live broadcast. Most captioning production company can
display a dialogue to maximum of 220 words per minute. If a dialogue
exceeds that rate. Selective editing is used to ensure that the captions
remain up-to-date with the current TV screen dialogue.
Interference caused by building, power lines, thunderstorms, etc. may
cause scrambled or incomplete captions to appear.
Broadcasters may at times use a time compression process to the actual
program so that additional advertisting time can be given.Since the decoder
cannot read the compressed information, captions will be lost.
The videotape was either an illegal copying or the tape duplicating company
accidentally left out the captioning signals during the copying process.
You are in the TEXT mode. Select CAPTION mode or CAPTION (OFF)
Sometimes a performance problem can be easily solved by checking apparent but often overlooked
possibilities.
Before arranging for service,check these items. It could save your time and money.
