This is the Graphics Interface Board from the Human Interface Modules out of an Electrospeed III Baker/Hughes submersible drive. The sun burns out the LCD screens. How hard is it to get these screens?? I can buy the HIM's for 3300.00
 
I guess we need some pics....

I guess my question is, are the screens themselves proprietary??
 
Further disassembly is required......hang on....
 
The sticker on the back says "Vishay" LCD-160H128E-WGK-NZ, next line...WG160128E-WGK-NZ#

Coolness, I was hoping it would be that easy...obviously this is an E model with different reflective options, and I'll have to demount the power harness....but this appears doable. Whew!! We really didn't want to cough up 3300.00 for the complete HIM. I disassembled the touchpad on one the other day and got it working and back together, and it's now on the Collins Fed #1 doing it's thing. I have 3 of these to do Joe. Where would be the best place to get these??

You may want to try both the spark fun and Mouser. They are cheap enough compared to your controller and they appear to follow the same standard. Small risk if they don't work.
 
Yeah, my concern is the WG instead of the TK, but that might not be a deal killer.


What is this component added at the top?? Temperature monitor??

Not exactly sure Lee. Perhaps an opto sensor to adjust backlights depending on ambient light conditions
 
I know Joe, but an informed guess I would hazard, it does appear to have a clear section in it. Looks like a diode, but then , not.....these things are out in the weather under a clear plastic window. In the dark, daylight, you name it, bitter cold and steamy hot. It's a wonder they last at all. Some of the complete controllers have a heating tape that runs around the inside diameter of the display....
 
Left- handed hint: Cover the thing over with a piece of aluminum foil to protect it from the sun.

No guarantee...
 
I'v already started putting cardboard on the inside of the clear cover...
 
Got the replacement LCD screens today....minus the 20 point connector. Joe , looks like a surface mount .100 spacing connector.
