I've had this Maestro for about 4 years. I can see that I may have to replace the tablet with a new. What if the model A tablets are no longer available is this Maestro toast.

Bob, I am wondering the same thing. However a replacement may not be needed.

I’ve got the Maestro Model A also. Works 24X7 here since they came out. No problems at all!

Sounds like your internal tablet battery is exploding. The discoloration is from the battery expanding inside the tablet witch now has damaged the screen. So now the battery and screen need to be replaced OR the entire tablet.

I’ve had my Model A for 9 months and no problems at all. See no reason to expect any issues , or need to replace it.

He is asking if there is a new drop in replacement tablet for the A model to replace the old model.

Bob - sounds like a question you should direct to FRS.  If you decided to ask them, let us know what you find out.  I have an A model too, although it has worked flawlessly for the last few years.

Maybe we should be proactive and replace the tablet battery?
How difficult would that be?

The battery is not the problem. The screen is the problem, it starting to show some wear and tear. The bottom area has got burn marks and I noticed lately that these burn marks are getting bigger.

@Bob - there are some reports that battery swelling of the OEM battery, specially if left on the charger for years, plays a role in screen issues that look like "burn marks."  While battery swelling is not the only things that can happen to a touchscreen, it should be pretty easy to check out.  

There are community members who have replaced the internal battery themselves.  One posted photos of replacing the screen module and the battery.  Some have reported the battery change-out relieved the back-pressure on the screen and the "burn marks" faded for them.

A friend (W9EVT) had a spillage-on-Maestro problem and FRS did a great job of replacing his complete internal tablet, so that is also an option.  You would have to ask FRS if they can replace the screen and/or battery alone.

The "burn spots" are not from a bad display.  They occur because a swollen battery internal to the tablet pushes the LCD display out of shape in those spots where the swelling is concentrated.

I sent one of my Maestros that was having this problem and Flex fixed it.  The other Maestro with the "burn spots" problem of mine I fixed myself by purchasing a new tablet battery and installing it myself.

Works great and both "burn spots" Maestros returned to good as new.

So the question is what is the Tablet that is used in Maestro B ?   How does it differ if at all and if it uses the same tablet is this an age issue ?

The tablet does not use a hard drive, it has a digitizer board which controls about everything in the tablet. The software is loaded to memory and cannot be read if you do not have a copy of the imager provided by Dell. Furthermore there is a copy of Windows in the mix. To me the best thing for an individual to do is buy a tablet now and keep it for spare parts. Hopefully the digitizer board will not go south on you, if it does your dead in the water. FRS does not accept consumer parts for replacement.

It has Solid State Memory AKA hard disk. You would have to boot from a USB image utility then you should be able to copy the entire SSD, windows and all to a USB stick then transfer to the new tablet SSD.

I have not done this with the Maestro but have done it with other windows 10 tablets in the past. There are free windows image/clone utilities on the web.

 This is not easy and requires good PC skills but it can be done.

Worth noting is there were several variants of the Dell Venue 8 Pro tablet offered to the public (thinking at least six), as well as customized OEM versions offered.

There seems to be at least two levels of hardware security available, various master password schemes and several operating system variants produced. 

I'm thing that I might DYI internal battery changes, or just have it done at someplace local like Battery Plus, but at the low cost to have FRS replace a tablet I'm not thinking there is any savings to try changing the whole tablet if needed by myself.  

The FRS replacement especially makes sense knowing I don't have to try and source an acceptable new tablet, figure out how to get it configured and imaged.  That is stuff FRS would do for me?  I'm thinking that is my way to go if needed.

 I agree $150 is very reasonable for a replacement tablet from Flex.

When flex runs out of tablets and parts we will have to become “Ham Radio Operators” again and come up with some kind of mod or retrofit on our own to keep our trusty Maestros going. :)

Since you have it opened you might want to try some experimenting.   How about running a extension for USB and then add mouse control?  What about an extension to add external HDMI and a larger monitor.  Maybe some other creative things that the tablet can do on it's own but is restricted once installed in the Maestro.
