Ill have to confirm it by checking the component specs, listing description and then actually running it at 24v to see if it can directly run off 24v instead of the usual 12v, make sure the driver isnt overheating even though its in-spec.

If it works fine, i have a few challenges ahead of me; first, the fragile and tiny LED strip needs to be properly mounted in the reflector shield/case for the light tubes. In all likelyhood i can probably pot it and either end and run a little wire through to keep it fixed, plus glue the strip to the back of the reflector with thermal paste.

This is just a quick entry to mention that i have taken the monitor apart and extracted the CCFL tubes.
I have come to a few conclusions, i dont have much time to elaborate so ill just list them.

• The tape holding the monitor together should just be cut along the tear line, dont bother with untaping it, the adhesive wont reapply most of the time anyway.
• The monitor is held together with clips on the long ends and friction, plate on plate, on the short ends. the clips CAN be non-destructively unclipped and keep the monitor VERY secure.
• The Tape is probably just to keep dust out from getting at the backlight high voltage leads, if you are using an LED replacement kit you dont even need to replace it. If you are replacing the tubes, then you can replace it wil pretty much anything as long as that compartment is airtight.
• Inside the monitor there are plastic sheets, the main one making noise is a seperator sheet keeping the white background on the LCD and the touch sensor array apart, dont worry about it, its like 3mm thick plastic double sided taped to circuit board. Nothing important is glued to each other inside and the tubes are also very secure, the monitor will easily come apart, but DO NOT apply force to any glass/crystaline parts, ensure all levering is done on the frame and visible components only
• Remove the plastic shell asap, its not neccesary and can easily break if mishandled. It offers no physical/useable support whatsoever.
• Lastly,  you cant pull the monitor apart, you need to lever it apart, however while not quite apparent, you can do it entirely through the holes in the side  frame, levering off the threading that normally sticks through said holes, its the only safe way to apply even force and lift the backplate, ill provide images and diagrams later.

As of yet since i have taken so many parts off i havent been able to run the monitor yet to see if i possibly broke it.

Still, i have ordered a 540mm LED CCFL conversion kit off aliexpress, the slot to fill is 11x7mm, and no diffusion lens seems to be used, although some sheeting exists that reflects light shon into the screen, the lights just shine in the LCD glass through the side, which is very thick and seems to make up allot of the product weight.
Because of this, underpowered LED strips might leave impressions in the lighting consistency.
In all likelyhood i will probably need to use my own driver for the LEDs

Practice disassembly

From time to time or more regularly ill give entries titles for the sake of the wordpress logs.

It occurred to me on an unrelated subject that I was concerning myself over the specifications of a raspberry pi to use in my car when I already had a junked netbook which besides the cracked screen worked fine and would work fine as a superior capable replacement that could be trusted with something data intensive like higher resolution dash cam use.

I opened the Wacom up and begun unpeeling some of the protective tape holding the screen together, I also undid some screws, I found that the 4 black screws around the monitor hold it onto the plastic frame, also, two metal rails cover the top and bottom of the screen and are glued to the underside of the plastic screen that you write on. Attempting to remove it for better access may cause serious damage to the LCD indirectly.

For this entry I don’t have much to say progress wise though I do have some new thoughts worth mentioning. Many people claim that a new power supply momentarily fixes the issue, this may be because the new supply has been fried like the old one was, or, the new supply is handling the HV leakage differently, so progression of the tube degeneration has eventually caught up with the new supply also.

The problem observed is that the Wacom monitor fails to turn on properly. When the power button is pressed it boots up normally and displays an image for about a second, then the screen goes black and appears as though the monitor has failed, however all the other lights are still on and the computer still recognizes the monitor as being active. Shining a light on the monitor shows that an image is still there, just the backlight has failed.
