Joe - here is a much better alternative: https://www.radioworld.co.uk/yaesu-ft857-ft857d-replacement-panel-screen-cs2140401 Whether I'm successful or not re-flowing the display connection, I ordered a

Thats about where I went.. 645. F which is just a little less. I just saw a little at the edges of the solder.. Have you tried it Howard? -- 73 Brad N8YG

Brad - how hot did you go with the air? I went up to 350C and didn't really get visible flow - trying to be careful not to cook the board! 73, Howard

Also, if that doesn't do it.. you may try the fingers that attach to the LCD and last resort, hit the Display driver IC with a -little-heat.. Also I read somewhere that that lens? is directional..

Howard , You can clearly see where to reflow with that picture.. where the flex attaches to the pcb.? ?Yours looks a little like mine did.. so hopefully it's good news. -- 73 Brad N8YG

OK - video to follow showing the re-flow - nothing to loose here as my display is very bad - if this is a fail I will buy a new assembly before they disappear! Fingers all crossed - safety gear on!

The theory and practice often miss.And most of the theory / rules are more legal issues then technical issues. The "what if..." legal speculations prevail? instead of real technical reasoning. Let's

You actually have to deconstruct a bit further. on the picture on the right there is a black paper tab in the middle that is stuck to the bottom of the board.. Carefully peel that back.. from the back

PLease point me in the right (exact ;) location to reflow...thank you! 73, Howard, WZ4K

That's awesome. When I heard the 857 was officially discontinued, I bought another control head because mine started having the stripes. I'm going to try this on the bad one to see if it clears it up.

Hi All Here in the UK we used to fuse both positve and negative supply lines in accordance with the radio manufactureres instructions.? As a vehicle electrician I never liked that idea because it

Theo & all, I aimed the hot air at the connection point and kept is moving a little.. enough hot air to just? reflow? the solder but not scorch things. No one was more surprised than me that it

By fusing at the battery you protect both the radio and the wiring in case of a radio failure or a short to the wiring. By fusing both positive and negative you protect the radio if another high

What do you mean by "longer period of time?" Remember, the purpose of the fuses is only to protect the radio in case of a short, thus preventing a fire. In the case that you develop a short without

At some point it was discussed and recommended to fuse BOTH positive and negative leads, especially in mobile installation. In my opinion unnecessary and to be truthful? I woudl NOT use fuses at all

Good work. Did the flex/ribbon cable not melt when you hit it with hot air? Regards Theo VK5IR wrote:

I unfortunately didn't take pics. That was a bone head move for sure...and I always take too many pictures per my better half..lol.. The solder looked like it had flux all over it and as I reflowed

Brad, you may want to set up shop and fix these for folks. I would pay?some good cash to have mine fixed if it were that way.?Your method of repair sounds stable. Thanks for sharing.

Hello Brad, Thank you for the post. I have loaned out my 857 to a newer ham. When I get it back, I'll bring it to work where we have hot air rework stations.? The idea of working one side, then the
