First of all, sorry about all the site blackouts, im on a free host so thats the price i pay, soon ill hop on a paid plan though.
Second, everything is ready. I made a first video, its much longer than it needs to be and i think i rambled on, im editing it now and will upload it soon.
What i did was identify the 24v wires from the monitor as i removed the original inverter with its cable set, then solder the LEDs to the step down converter and tune them to the maximum safe operating voltage/output, im pretty thorough and explain how i go about working out the peak voltage, as i also have the current on display at the time. Long story short though its 1000-1200ma. I probably should have just soldered only one of the LED wires then connected a multimeter in between to measure output current instead of using my power supply set on 20v and doubling the current to determine actual current but whatever.
That video will be uploaded and done before i work on the full disassembly and installation video, its really the only hard part anyway. In the installation video ill be using a lot of photos, not still frames though, i mean actual quality photos as i always do in here, in certain parts of the video while i explain something or it needs a better view. I probably might also end up using my mini tripod or just holding the camera as i do certain things, its something i only want to do one, but also right.
Essentially though it should serve as the final entry for the wacom 24HD repair project, and as the complete guide for installing the LED strips, despite not including the details of how i determined the maximum voltage. My original estimate was correct, based on the fact the original LED controller was designed to power 1 strip only despite having two parallel plugs and still only supplying the same amount of power for 1 AND 2.
Its not that hard to set the step down converters output if you have a multimeter or an XL4015 with a built in volt meter display and/or current display.
Hey there Joe!
Did You upload video somewhere? I’m curious about that repair…
nah sorry, got sick after my exams, then it kinda slipped my mind, ive been in a massive haze until now. If i cant finish editing, i think i might just upload mega links in the mean time to the big mess of footage
Hi
What can I do to help to make you upload the video faster? I’ll donate 50 bucks if you upload it.
im working on it now, sorry its taken so long to reply (ive been sick, see the new post) , i sifted your comment out of a shitstorm of spam.
Anyway, i would certainly welcome the donation for sure, i have some new projects comming up that could benefit from a project fund, one of which will be custom made LED strips using 5730 leds (5730 is the type, means 5.7x3mm), they can be really bright, though it will come much later, atm im asking aluminium PCB manufacturers for the costs of raw single layer 7mm wide strips, not getting straight responses without circuit diagrams to show them.
As for what you can do, just be patient, though i certainly would appreciate any respectable advertising of my blog in anywhere you can think of.
Hello Joe
Is there a good recommendation for CCFL to LED backlight conversion kit? and usually how long does it take to do the conversion? Is it better? and How is it working now? thank you in advance.
Alex
Any updates?
video is done, im currently using my monitor again, just editing it down
Thank you so much for documenting this process.
My 24hd Cintiq decided to break this weekend (right before finals!) thankfully I have a backup display and tablet… But I am so distraught over my 24 failing.
I’ve been searching for fixes all morning and afternoon, because I’m pretty sure my warranty is up and I’m not sure where I can find my purchase records after moving everything around in my studio.
I hope I can resolve this issue, as the display has worked fine up until this morning. Occasionally it would turn off after my computer went to sleep and had to be turned on with a reboot, but I didn’t think much of it.
I look forward to any videos you post.
If my warranty is up I’m definitely interested in trying to do these repairs on my own with the help of a more tech savy friend.
My only concern with LED replacements is color calibration. Will the color quality be comparable?
My cintiq had a problem already with colors appearing different compared to other monitors. Namely on characters colored by pallet, they looked much more different since the varying shades of purple and pink didnt mix as well.
Moving to LEDs, the problem persisted with no difference, i cant tell if the cintiq is displaying true colors or not, but, it should be the same.
CCFLs dont output as narrow a spectrum as LEDs do, so in a way, LEDs are superior. The backlights i recommend are all pure white, not warm or cold. CCFLs change over time.
Anyway. Short answer, odds are colors will be the same on LEDs as CCFLs, if not slightly better on LEDs, and hours of callibration couldnt change that with the CCFLs, while on LEDs, i never felt the need to.
I did a side by side comparison once with the LEDs and CCFLs, they looked roughly the same too. Normally if theres 1000K of difference it sticks out, so, id say they are within 1000K of each other if not almost exactly the same.
I’m looking forward to the video. Thanks for taking on this project.
Ill do the video as soon as i can. As i mentioned before though, while not as good as a video, i did document the installation of my lights the first time around so the information is all there. I aim to record the video in the comming weeks once im no longer dependant on the monitor for my studies
