DELL U2515H 1440p Monitor NOT WORKING - Can I FIX it?

Nice work Vince - I am watching you on dual Dell U2412M monitors with the same stand features - these are great/fantastic monitors for folks who don't need 4K!

Awesome fix there, you make it look easy! I’m still struggling trying to get this new tangled lead-free solder to stick 🤣

I like the way the PCB is labeled!

Nice capacitor discharge cable! A double fuse protection. Interesting! I have a Dell 24" 1200p monitor similar to yours, has a problem where it won't turn on, no power light .. haven't opened it up yet, am watching your videos! Thank you 🤓 300 + VDC? I will take the same precautions!

Switching power supply’s go all over the place until there is a load on it. 15N15 is a 15 Amp @ 150Volt Drain Source Voltage N Channel MOSFET.

I got a Lenovo 22' monitor off freecycle and the insides were almost the same. The back of my finger touched the 400v cap (ZING) and measuring it AFTER it still read 220v

Also I got different error codes on the led when the AV board was hooked up to the power supply.

Hi Vince, I found that if you put in the search Mosfet N15R, you can find data sheet, along with equivalents.

Hi. I did the exact procedure with my not working Dell screen. (Did not succeed though!) But when looking at the old MOSFET, same as yours I assume without the metal heat plate I could see the small text on it It is a PK7NK80ZFP (GKO1Y V33 CHN 542) Good luck for those others trying.😊

In my case the power board seems fine, I get all the 20V as you show in the video. How would you recommend approaching the fix of the other board (the 'non power one')?

Well done! Feel good video!

this is inspirational, seriously thank you!

Hello Vince! Great vid! Question: can i delete this monitor's power supply and use a 12v-to-20v booster to power it up? I have three of these and a motorhome, and it's a lot better than the motorhome's TV but i don't want to run an inverter for it. What do you think? Thanks!!

good job dude

You did a good job. "I also have the same model LED that does not light up." It helped me find the fault. thank you

Excellent Troubleshooting skills.. Very easy to the beginners to learn a step by step procedure to fix the Power supply issues.

This video saved me $200 and kept one more monitor from becoming e-waste. My monitor had a different problem (blown fuse) but the diagnostic procedures in this video taught me what to check. Thank you.

Very awesome episode. My 24' dell monitor power died so I queried if I can just add a 20v from a different PSU and tape it on and the guys said there is probably some complex power system with 5V going to other rails and it needs a custom PSU.

@mymatevince your vids are wonderful

Up the amps

I love when Vince goes "Hi I'm Vince from My Mate Vince", like we didn't know what were watching 😂

Trying to fix the same model monitor myself, tested the psu & got 19Volts out of it, so assumed it was ok, did not try putting power direct into the main board though, perhaps I will take it apart again & do that. symptoms are no activity of any sort when plugged in.
Bob

well done

Hate to break it to you, but Dell sucks That’s why they keep breaking. Any Dell products

Hi Vince it’s been a year now is the Dell Monitor still working? Keep up the good work bravo 👏

I should have had paid attention in tech class lol

Could also use a plastic screw or a rubber push plug to hold it against the heat sink

if Dell was a premium product it would still be working.

i have the same sdesolder station

"easy fix" why didn't they fix it then?

Stop cutting your finger nails so low

hello sir can u help me i have a dell u2715h monitor when i start my monitor or change the video resolution monitor brightness and contrast goes to zero no idea how to stop it from changing

Greetings. Thanks for sharing and thanks to the educational and informative responses provided by the commentators respecting mosfets specifications and operations. Thanks.

On what planet is dell a premium product?

Vince, would Nylon screws work for similar purposes when you need insulation from shorting on a mosfet?

I Need this monitor Power Supply circuit diagram . Or send send clear photo of soldering side. I want to know the value of resistor R9818. Please send if anyone have.

if the fuse is good, look at the small-cap (1uf, 10uf ) something small in uf....that nr the chopper transistor, also a resistor.

Was there enough space to paint the screw hole with solder mask?

never heard someone to be so relieved to have no HDMI cable lmfao

One thing I noticed that you are cleaning the device with much care 👍,I can feel how much passionate you are. That shows you are a very good technician.Keep up the good work 👍👍👍

Genius Vince. Awesome job.

I have very similar project to keep me busy. Another department at work was throwing away a Dell U2713HB monitor. I just didn't believe it until I tried it out -

Well, the Dell monitor is strange as it powers on fine and displays the "select source" screensaver but no matter what source I try - VGA/DP/DVI/HDMI - it just doesn't want to connect. I've tried all possible cables and devices as source.

I suspect this is a fault with the image driver board rather than power supply. I just need to find it! 🤞 One advantage the image board should be running low voltage?

Any pointers are greatly appreciated.

I want to make a basic flight simulator rig to teach Scouts flight theory and as a primer before having a real flight in light aircraft. I was inspired by "the warthog project" - just something a bit more civilian/peaceful. Only I need to find this stuff as cheap or free🤷‍♂️

What camera do you use

These videos are like therapy to me lol

Nice job Vince. As StezStix Fix says that is a 15N15. I think the case style is called a TO220-3-313. What you need with what you have there is a smaller diameter bolt, a mica or other isolation pad and a little plastic washer that has a flange that goes inside the hole to keep the screw from touching the metal. I think it is called a TO220 mounting kit. What you need (I think) is a IPA105N15N3 G which is a 150V 37 amp Mosfet about $5 american from DIgikey. I think what you put in is 9.7A at 100V. I don't know how long that will last, not because of the current draw but the voltage.
Keep up the good work. (I did subscribe).

Just wonder what happy
try this DELL TV monitor is maKe in MADE IN AMERICA

Hi Vince. Old history now I guess, but a more permanent solution for the conductive tab transistor is to use a mica washer which come in all shapes and sizes to suit - beware they are VERY delicate! + & nylon bolt (or through hole insulator if using the original bolt) with lots of lovely thermal paste

All it took was one tiny component to make it work again. Save it from the land fill
