Any one else order a replacement screen form England? How much trouble to install.

I received one yesterday but I only got it for a spare, there are videos on YouTube on how to fit it, its easy but you need to unsolder 1, 4 pin socket at one end of the board and re-solder it to the new board.

I just received one. ?Haven’t done anything with it yet; I’m going to try resoldering the existing one first.

Hi Bruce,

?

I replaced one in one of my 857s a couple of years ago, Wasn’t too difficult.

?

I obtained mine form a local supplier here in Australia.

?

I still have another spare for when my other one eventually needs replacing.

I ran mine in my truck in Florida for over 10 years before I started seeing the zebra lines. In the summer, the inside temps in the truck could easily reach 120 degrees.

I have had my FT-857D from 2011. It started getting the tiger strips last winter. It is in my car all year in Chicago weather.

This is where I got mine:

With the discount code it was less than $140 including shipping and currency conversion. ?About 10 days from order to arrival, in California. ?

Seems like a good deal. ?I haven’t installed it yet, so maybe it’s the British left-handed version or something. :)

that's where mine also came from, they just had a new delivery last week, seem to be flying out the door since the 857d was discontinued

I got the part from Radioworld today. It was ordered on the 14. They sent it UPS in a box that would hold a suit. Had a little trouble installing it. Hardest part was de soldering the plug. In order to put the new part back in the case you have to wriggle it a bit. Seems to work OK now.

Hi Geoff,

In addition to whatever Eric might respond, I’ve just purchased one from Andrews Communications in Greystanes. $199 delivered next day.?

I was considering one from Radioworld in the UK but finding it locally at a lower delivered price swayed my decision.?

Hi Geoff,

?

I think I got it from a mob in Melbourne who repair and supply parts for the radios.

?

Ross at Strictly Ham put me onto them and the guy he put me onto was Guy, but I don’t remember the name of the company.

?

OK, disregard the above, I just found the invoice.

?

JNB Electronics P/L

42 Latitude Blvd

Thomastown Vic 3074

03 9465 9399 and ask for Guy

repairs@...

?

Part number for the panel is CS2140401 FT857 Panel Unit

?

Cost when I got mine in March 2016 was $165 + GST.

Hi Eric and Mark. Many thanks for that, a great help. 73 de Geoff vk3sq.

I ordered from Radio World. Excellent customer service and received quickly to Virginia (by way of CA for customs inspection). Yes, desoldering the 4-pin connection was troublesome - I am not very good at soldering/desoldering. I went ahead and ordered replacement 4-pin connectors and the Pot/PC board assembly from Yaesu (pictured). The 4-Pin connector connects from the replacement board to the AF/Squelch Pot assembly. The pot assembly is easily removed from the face-plate with the typical knob retaining nut. Here are the Yaesu part numbers:
Description? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?Item ID? ? ?? ? ? ?Notes
Wire Assembly AH007M? ? ? ? ? ? T9207024? ? ? ? 4-pin wire assembly with connectors
VR-UNIT? ? ? ? ? AH007M00? ? ? ? CS2592101? ? ? AF/Squelch Pot with integrated PC board?

Yes, I ordered several spares knowing how bad I am at soldering...but it went very well.?


In this view - the ground connection is all the way to the right and is noted by a line next to it. Likewise, on the replacement screen board - the same - ground noted by a line. I connected with the yellow going to the ground connections.

If you look closely at the attached parts diagram - there is also a foam "Sponge Rubber" border that goes between the screen and the case - I ordered that too and used alcohol to remove the old adhesive from the window.

The parts were inexpensive and the entire transaction was conducted via email with
b.velarde@...

I 'killed her with kindness' and received relatively prompt replies and responses - but not much in the way of friendly dialog! No complaints!

With these replacement components - the screen replacement is super easy! I agree - seating the display board assembly back into the panel requires a bit of finesse but take it slowly and it will snap/pop into place. The 2 screws will properly seat the board and ensure the Select pot/knob works properly.

Hope this was helpful, 73, Howard, WZ4K
