A common technique is to pre-process your input image. Resizing produced good results.I also use psm 6 for these types of image with various text locations.
In this case I first used your cropped image: tesseract ArrisVIP2500_cropped.png out -l eng -psm 6 config and got: AT&T U verse rowsn O F3. vrrzsoo ’e' Then I resampled your image to 2000px wide: tesseract ArrisVIP2500_cropped_2000.png out2000 -l eng -psm 6 config and got: AT&T U verse POWER © " ‘| / ‘j""'j"’..
