I’m looking into the purchase of someone installing CCFL lights into my figure’s sabers & guns.
My plan would be to have them on/lit whenever I am in the man cave at night (4-6hrs), but never all day or overnight.
I’ve been told they can get quite hot and should really only be used when showing off display since it can potentially warp the Saber hilts etc.
Question for those of you who have had this done. How long do you typically keep them on without worry? Do you have them on every day or only every now and then, if so how many hours at a time? Do you notice any wear or warp on the figures?
Any other dangers or risks I should know about?
Thanks in advance! :)
I have Vader and Qui-Gon coming in in a couple of months and I just wanted to see what some recommendations you guys have.
I was repairing a monitor, and from the symptoms (1-2 seconds of backglight and then it goes dark) I just assumed a bad power board and ordered a new one. After the new one produced the exact same problem, I now think it's probably because the CCFLs are drawing way too much current, triggering some safety mechanism. This is also supported by a very burned out power resistor near the CCFL's port on the old power board.
Is this a common failure mode for CCFLs? If so what's the science behind it? I've been researching it for quite a while and haven't read anything similar yet - if anything, from what I understood they should draw less current as they get older (since there's less emissive material on the cathodes and thus less current can flow).
Dear r/AskElectronics
I found an old monitor next ot dumpster and decided to try and fix it. Upon connecting I saw that screen was all blocky and jittery. Found out most of caps on inverter were blown and replaced them. Turned it on again and there was still some color issues, probably due to some problem on the logic board (or whatever it's name is) so decided to make some nice light from backlight.

Problem is that it seems that it need some kind of communication of a logic board. I think ON/OFF and PWM DIM pins must be on in order for it to turn on. I measured 3.3V (in relation to GND pin) on them when backlight is on (it flashed form about 1 second upon turning it on and then switches of) and about 1.5V when idle.

So I tried giving it 3.3V on ON/OFF by reducing voltage from 13V pin and also giving it some PWM from simple 555 timer on PWM DIM pin and nothing happened.
Do you have any ideas as how to make it work?
Thanks in advance!
Yes, go ahead and get your laughs out of the way, but I use a Lenovo T60 as my laptop. Runs Win7, not a lot of issues. However, for a while now I have been getting the reddish hue on startup, and now after a few minutes of use, the backlight just urns off and won't turn back on until I reboot. From my reading it seems the CCFL is dead and it's not something that can realistically be replaced. I tried plugging in a external monitor and that works fine, so I think that conforms the CCFL aging out as the culprit. Would you agree? I just find it weird that the display works fine when you reboot and doesn't turn off until 5-6 minutes later
So I need a new LCD panel. Luckily for me, I have a spare T60. So I fire that up, that has Window 7, but when I use that laptop, the screen is giving me really bad eye strain. Also, even though both are listed as T60, the second one seems different. It's running a 64 bit version of Windows vs a 32 which suggests a different processor, and it seems to be running faster than the other one (although that could just be due to it being a fresh Win7 install).
So since I cant use the new one without getting eye strain, I am going to do a shell swap and see if by change it is a different video card causing an issue and not the display. So first question, did T60's all use the same panel (it's the 15 inch one) bu different video cards?
Second, if the swapped in panel cause eye strain, where is a place to pick up cheap replacement panels?
Is there anything I could check to tell me any hardware differences between the two laptops I have?
In my recent adventures to mod the new 4-in-1 Partycade that comes with a new mysterious LCD monitor that has no know LCD Controller Board yet, I am instead swapping the LCD for the panel from a DELL 17” E177FPf monitor.
As it turns out, both the Arcade1up M170EGN01.1 / M170EGN01 1 and the DELL LCD panel (M170EG01 v8) can use the same LCD Controller Board (M.NT68676.2), but my Controller Board didn’t come with the proper Inverter board for power.
I know that some controller board that people here ordered from Amazon, eBay or AliExpress came with the Inverter board that I’d need, so I’m looking of any of you, preferably from Canada, would have a spare Inverter board that they’d be willing to send my way.
It would need to be one of these universal 4 lamp CCFL inverter board as pictured.
