    FT 857 control head LCD (zebra stripe) repair. If you have the zebra stripes on your Yaesu 857 Control head and would like a crystal clear display again this would solve that problem. I disassemble the head completely. Clean everything then I install all new electronics (control board with new LCD) from Yaesu. This repair will also fix a defective head. US. $240 + $10SH. I accept PayPal, Credit Card, check, or MO. Phone number 816-223 3246.

    Cool, but calling replacement repair is misleading
    But that don't look like zebra I have seen or been told about.
    That is pretty much "goner".

    The consensus of the FT 857 users group always been exposure to environment - going mobile - is primary reason for this failure.
    The LCD contacts are just by pressure on the supporting PCB - sometime it can be resolved by "more" pressure - the question is how to make it permanent.

    Of course cheap design has always been my view of the problem.

    My zebra is pretty much a moving target , never been mobile but was used on few Field days in humid Texas.
    When I get ambitious and zebra gets 5 or more stripes I'll try the "zip-lock bag filled with rice " trick.

    Shirley, you are correct, this is an environment caused failure. Older radios in mobile service in hot summer environment do develop over time the LCD issue. Every repair I have done has been on heads from the southern US and a few from Australia.

    You are also correct, I use the term "repair" because I consider this the repair of the Control Head not the LCD. I have a box of old LCD'd and I have tried to find ways to repair them but never found a lasting fix. This approach of replacing the control assembly also allows me to turn around the heads a one day.

    I also want to add, I love the 857 and her sister the 897. They are amazing in that you have a 100 watt HF rig plus 2 meters and 440 all in a package the size of a CB. They are also easy to fix at a component level for other issues beyond the LCD, I love repairing them.
