Screen 'staining'

[Zflyer]

I have had something similar on Spektrum DX6, but there was no remedy due to obsolete parts. I am hoping for a better outcome with the DX8 which has developed the same sort of symptom.

I say symptom because the cause maybe different. Just wondered whether others had the same symptoms.

Is there a contrast adjustment for the screen somewhere on the PCB?

 

What are the screen dimensions and are there any markings on the display to identify exactly what it is?

That looks like it may be caused by moisture condensation, it's vulnerable to this if you put your transmitter on the ground between flights, or keep it where there are large temperature fluctuations . 

 

I keep my Tx's indoors & use one of these on the field to avoid the issue:

This happens when the metal/metallic layer backing of the LCD starts to deteriorate with age. Have seen this happen to a kept in original case (with silica gel packs) in a new Futaba 9CAP . Luckily the spare LCD was available then

That’s why between flights I always prop my transmitter up against my flight box or somewhere else convenient, facing AWAY from the sun. Lesson learned a number of years ago when I went to pick the Tx up, and noticed that the LCD had completely blacked out where the sun had been shining on it.

Its off to Logicrc for a new screen. Hopefully that will be all it needs and there isnt any underlying issue!
