Fujitsu P20-2 CCFL to LED conversion (#P9)

Okay, so here’s something that I wanted to do for a long time, but it makes no sense in terms of time and money. But hey, I finally did it and it was fun!

I’ve shown my old Fujitsu P20-2 monitor previously as a comparison to the current 3440×1440 setup. It’s an old prosumer-grade 1600×1200 display, 20″, 60 Hz S-PVA panel with VGA and DVI inputs. Really good stuff. I got two of them after they failed by the dozen at university, where the tech guys even did a capacitor swap (these were in the upper three-digit Euro range when new, their replacements are totally overpriced 2560×1440 displays for 700€ a pop).

Lenovo Thinkpad R400 LED Display backlight fix (#P3)

Yes, it’s running in the “projects” category, as “quick and dirty weekend fixes” isn’t available yet :mrgreen:

While I was hosting my brother, he casually asked me when I will fix his display. Umm…what?
Turns out, his Lenovo R400 was showing vertical stripes again. Like these:

(jup, stolen from some Apple customer help page – I didn’t take a photo at the time. I guess the bug is a watermark, isn’t it?)

I’ve already seen and kind-of fixed that on my visit shortly before Christmas last year, when I basically had no tools available. […]


Müller Licht 5.5W/220-240V/50Hz/38mA/470lm/2700K/dimmable/E14 EB1500665 40036 (WHL #12F1)

Another one bites the dust :suspect:

Three months after the failed E14 LED light bulb in WHL #12, the second unit (out of four) died. It came back to life a few times (a few seconds each), and I reckon now the magic smoke has finally escaped.

All of the remaining bulbs show this distinct yellow shading on the diffusion globe. The replacement one still looks white, like shown in the previous post. But this one clearly failed…look at it, I think it sneezed one single LED off the board. Bless you! […]


Müller Licht 5.5W/220-240V/50Hz/38mA/470lm/2700K/dimmable/E14 EB1500665 40036 (WHL #12)

Bit unusual item today – a plain E14 LED bulb that is sold in Germany, made by a German company, but I suspect it is made in China. Müller Licht has some stuff actually manufactured in Germany as well, but I don’t think this one was. But as it is not clearly indicated on the bulb and/or on the retail package (as far as I can see from product photos), I cannot say for sure.

Well, this was one of four identical bulbs that I bought for replacing halogen bulbs in my new home. I cost me 6.39€ a piece back then, shipping was free due to buying loads of other stuff and easily surpassing the free shipping limit at one of my favourite shops, voelkner.de. […]

Well, you get the idea. It’s LED strips this time, and I chose 5630 size in warm white color. I’ve been ordering quite an amount of these, and in hindsight, I would rather buy A LOT of them instead of getting 1-2 reels at a time. […]
