Historically I have fixed similar problems were vertical blocks have been displayed - due to partly un-bonded tab bonds . But fixed by re bonding with hot glue 
However this is an LCD is a Dell AIO unit and is a PITA to access the bond tabs for a play around
The image is similar but not the same as ( through experience ) a panel with perished tab bonds . But before there would be complete sections missing . As pictured the display is still there but there are bright bands vertically across the screen . The most irritating part is the wide band on the right - which I suspect is a bad tab bond
However I did not want to strip the whole set to find the panel can not be repaired
If I can fix this band on the right, I am happy to disassemble and fix
However on the other hand , the screen is still usable , and to the untrained eye it would not be noticed and possibly would be forgotten about - if sold on
Your thoughts?
God bless
