HOW TO FIX HP LCD, monitor turns off after 3 seconds (common repair)

Still helpful after all these years. The 3 second issue, and no visible cap issues, caused me to explore into the LCD. Sure enough the ribbon attached to the actual LCD separated, and I was done, but found the source of failure and Ozone smell as a shorting to the metal bulb housing on just one. Any vids on that repair. Could never get even those exercise bike B/W LCD ribbon to reattach, with heat.

saludos desde Perú, gracias por los aportes lo voy hacer tengo un monitor hp de 19p prendía y luego se apagaba

Hi, i have VK193D ASUS. When i turn it on, after 5-30 minutes, my screen goes off. First the bright goes lower and then black. If i turn it on again, right away it goes black. I need to wait so i can watch it for 5-30 minutes. I think that monitor have heating problem? How you fix that? Is it capacitor i need to change? Thanks.

Same problem ,but is not capacitors or backlight loose connection, what can be?

My monitor is gray now when I turn it on, any idea?

Hi sir does the indicator light at the power button working?

Hello, I need the HP 2210m monitor BIOS file
Can someone help me where to get it?

Subscribed. Tomorrow I´ll fix and AIO thanks to you.

sir i have an lg lcd 42lc55 and the problem is blinking the green led 7 times after stabilizing about 10 seconds and i can see picture with the help of lens and after goes out
do you have experience with similar problem ??

I'm curious if you have any ideas on my "strange" issue with an HP 2311x monitor. It will run just fine EXCEPT when I go to maximize any sort of video or even a picture to full screen and it will then shut off and reboot?! Does that on both a Win 10 machine and on a Raspberry Pi 4.

thank you for the video. But it is a waste of time for a screen worth 50 bucks

well done good sir

Little known fact, "HP" doesn't stand for Hewlett Packard, it really stands for HUMONGOUS PILE! I dunno how many owners of HP products have come to me with major issues over the years, but I personally won't spend money on anything that has HP on the label... Junk!

Thanks for the vedio... just a question, I encountered a simila problem with LG Flatron w2242p monitor which swith off after three seconds.... Is it similar case to this vedio which i can troubleshoot it, or any possibilities there for me go about.... Please I need your ASAP...
Thanks Joan Toa

im getting some soldering gear in today to fix my screen so yee exsited

lot of work 120 buck i get a new one

Probably what happened to mine. I would fix but I'm done with HP (having problems) I have a tv that will do nicely.

Thanks man 😊

Thanks bro, you helped me save 9 monitors for my home setup. I just needed the tubes. What I learned is my tubes were fine after 16 years on HP 1730. What fails on this model is the output coils secondaries. The low height transformers that are about the size of a stamp. These are hard to find so you might have to rewind them. Old HP were built like tanks.

I slapped my monitor after seeing that i dont have the tools to do this, its works now, i guess its not burned or something

hp lv 1911 এর monitor / Display আছে??

This is one of the best how to videos I have ever seen.

What voltage is required to turn them on ?

Mine just started to do this. Same monitor. Hopefully i'll be able to fix it. Thanks for the video!

I never encountered so much hassle just to disassemble a monitor.

Update on the newer model

Hello,

I opened my HP 2210i monitor because I have no more images.
After taking everything apart, I realized that on one of the 2 backlight bars, the neon species are broken at one end (the one where there are the 2 wires). So I can't glue them back together or solder the wires again like in the video.
Also, I was wondering where to find the backlight bars to replace mine? The only reference I have is 1P-9CT91DFfN9 and I can't find anything on the web with this reference (even partial).
Thanks for your help and reply.

Have a good day

Hi sir TampaTec, thanks for sharing. I've replaced all the capacitors in in my Viewsonic (its two boards) but it still turns on, then after 30 minutes it'll flicker in 8 second intervals? After the capacitors, with this symptom, what's the next one to check?

Thank you. God bless, Rev. 21:4

HMILS XP 1000 monitors do not turn on

Hi

Hey, turns out the LED isn't the problem, it's something else. What could be the problem (turning off after few seconds)?

goog work nic

Hey I have this monitor but it doesn't turn on at all I can heat it powering up so there's power but the screen don't come on at all and the led on button at the top doesn't light up either. Do you know what would be the issue with this?

ATTENTION: Notice the burn marks on the end of the tubes? they are close to end of life. Better to just replace the tubes while you have them out. Those probably won't last but a month or two longer.

I think I have this problem, my only question is, do I have to do this for all 4 rubber pieces?,

it's too complex.

Tengo mi monitor lcd q solo seve la imagen en la parte superior unos 4deos seve las lamparas estan bien como se repara ante mano gracias

hi i have a acer x223w moniter it comes on the go dark i change out the capacators but the same problems do you think it is the bulb?

Thanks for the tip on the burned out wire. I took the disassembly slow, but got it done without breaking anything. The monitor is back up and running.

I will just add that hot glue.. on a surface that gets hot.. doesnt work.... it will for a bit, until the surface gets hot and the glue melts off and goes where gravity is telling it to... id use heat shrink or super glue or high temp hot glue (higher than the operating temp of what your trying to glue..)

Windows 10 has a peculiar behavior after 25 days booted up--it turns the monitor off and on once per second when the monitor is supposed to be on standby'/sleep mode.
After a number of times doing this, it must have burned out one of the backlights on my LP3065, because the entire monitor is half brightness now. Still evenly lit, but 50% of normal intensity. Odd thought, because when a backlight fails, usually half the monitor goes dark.
Very annoyed at M$ for making an OS that does this destroying a perfectly good monitor.

Nice work! What to do if my monitor is not turning on? I replaced my capacitors already? Not sure what else to check?

Lol

Not worth the effort.

Just wanted to say a giant Thank You! I just used this guide to repair an HP 2509b monitor.
I was very skeptical because both lights were going out, but fixing the burned area on a single bulb unit seems to have done the trick.
All the best!

easy fix!

Can we use the tube outside of monitor and what volt use to tube?

Isnt there hi-voltage in modern LCD monitors? Are they safe to open and touch while testing? (I mean: except the 220v power transformator area, of course)

hi, i have reached till the last point of the video but do not see broken wires in the tubes. is there anything else that needs to be checked

Ang galing nmn..sana all my loptap
