I love this monitor and still use it to this day. I didn't have a lot of money as teenager but managed to buy one used for 500 bucks. Surprise, surprise, it had a 3 dead pixels! I contacted customer support and they overnight-ed me a brand new HP LP2475W with a shipping label giving me 30 days to return the old one back. THAT is what I call customer service!
I recently got one of these for like 20 bucks and it's the best monitor I've ever had. No wonder it's so bright and warm, really fun to see what's inside this thing
Mine failed just last month, also bought around 2009. Amazing long life for such a monitor. It saw a ton of use, running more than 8+ hours per day. I've been trying to fix the psu and found a dead diode that I replaced but still no dice. Hopefully I can get it back up and running and connect some retro computers to it. Thanks for the tear down so I don't have to :) I was surprised buy the actual CFL tubes, I was sure that there was some cfl foil in it instead. That certainly explains why it ran so hot.
The inductors on the TCON is not for filtering, it's a part of the DC-DC stepup-converter that makes the drive voltage for the LCD-panel itself. The small FFC is a sync connector that makes sure the backlight PWM is in sync with the horizontal scan of the LCD glass.
I have exactly the same problem. And also 1 day replacement in Poland. New model have the same problem after 2 years. Still works as secondary display.
Omg! Thank you for this video, i just wanted to check caps as it is summer and this thing get realy hot. But i will not touch any boards as i can damage components, i will just use compresed air and blow this thing. Again thank you :)
I still use an HP LP2465 which is a 10 year old 24" 1920x1200 8bit SPVA panel monitor, it was the display that finally convinced me to switch from CRTs. The colors and static contrast are still great by today's standards, input lag and response time are really bad though.
ditto, at least, had a HP LP2465 before this one, and since I needed a decent monitor for work, just bought a pair of 2475w's for almost nothing. And as someone who works in graphics arts and photo, I still refuse to get shilled paying thousands on a monitor like apple cinema display or some Iiyma master pro that just both hides inside a Samsung panel.. Both HP and Dell are good deals actually when it comes to pro. hardware.
I've actually repaired a fair few tv's more recently, and the biggest I got to mess with is my own 65 inch lg whish had busted led backlights, and besides the backlight itself, most of the technology is the same up until the oled, and mini led stuff, which I find pretty surprising tbh
The purpose of the cutouts on the spark gaps is to prevent shortage once sparks charred the board. The charred surface would be conductive but the gap would still interrupt that trace.
Chances are that your monitor failed because of a dead Power Schottky Rectifier on the power supply board. Replacement is DSSK 60-015A (TO-247 AD) or V40100PG....
most manufacturers that sell to businesses and consumers have 2 different tech supports. business customers would never put up with the level of bull that consumers have to so they get better support.
Yep, I remember when someone at work accidentally called the consumer number for dell... basically just queuing and lazy bullshit until he gave the service tag number of the PC which was crashing randomly like once a month. After looking it up the dell rep turned from a bored "up yours, buddy" type into a peppy "Oh sir! you have accidentally dialled to the wrong number, just wait one short second and I shall dircect you to our business support right away!" -> better service -> no hassle -> immediate replacement :)
We use about 30 of 2440 series ones at work, pretty good for the price. One of them has failed in about 4 years of use. I repaired that one, one 1 meg ohm resistor had failed on the power supply :) Looked like a sense thing to the first 230 volt side power supply controller chip, there were 3-4 of them in series and one had gone open circuit.
That USB 2.0 Hub Controller you ripped off the board looks like it was a Renesas(NEC) uPD720101. I think that one is now obsolete. The crystal next to it should be 30 MHz IIRC.
6:21; indeed it doesn't have any screws, I would like to see how you open the... 6:23 okay; I see... keep your secrets! One of mines just shut down in front of me and I bet this is the PSU that blew a fuse.

you bought one HP LP2475W for $500 ? Now my deal 2x$100 looks even better... :)

VGA, HDMI, _and_ component: the high definition trifecta! What a great monitor.

That makes perfect sense. What doesn't is that they only did it on some of them. :D
Agreed

petti78 yeah I started my it career at a large municipality and was blown away the first time I had to call dell outside the pro channels.

I have the same lcd since 2008. It takes long time to find signal from displayport compared to dvi. What can it be? Caps?

Here I found another video how to actually open it: ruclips.net/video/RgErQwXrVSw/видео.html
@@philipdudin8039 yeah the HPs are strangely assembled, screws but no screws.
and i don't want to scratch its aesthetics.
