All the 857s I have run into have the stripes problem as well as the 897s. I worked on an 897 and the display was so zebra'd up it was almost unreadable. My 857D has one missing line and I knock on wood that there won't be more!So I treat my 857D like it is FILLED WITH NITROGLYCERIN as the slightest bump or temp change may cause more lines to go out. I am also bummed at Yaesu that they won't repair these like a warranty deal. But then the new displays they put in are just as subject for going bad as well. They have a similar problem with the very pricey FTdx5000MP, where the Little displays grow white lines. They also refuse to address that issue and have the sales people who do conventions pre-programmed at just what to say when Hams question them on it. The other manufacturers have similar issues, Icom has the IC-52 disease in 746PROS and Kenwoods have a DOT DISEASE on their displays for units like TS-940S and TS-450s. So all MFRs have coverups. Probably the highest quality builder is ELECRAFT. never heard of a problem on a K3!
