Question about HP L1730A (Carbonite, Silver) 17 in. Flat Panel LCD Monitor

Open Question

I have an Hp L1730 (PE1238) (P9625A) color flat panel monitor. I turned the monitor on and the image popped up for one second , then blinked out. The power LED stays on and green. I checked all of the cables - ok. I disconnected the cable and the no video signal message comes up. I turn the monitor off, reinsert the cable, turn the monitor back on - same problem. I can't find a service manual for this product.

SOURCE: I've been getting no power at all. Tried using a good known power cable and a different power outlet but still won't work. How can i open the panel to check the power button?

Hello emperez25...Sorry to hear that your LCD died on you. There are two things that normally cause this... #1..The power supply has gone out.... This would be the case if the lights on the front of the unit do not come on. You can check this with a multimeter. . #2...The inverter or the back lights are burned out. LCD displays use small tube florescent lights like the ones that are in stores and they either burn out or the inverter fails and they cease to work. This is the case if the front panel light comes on but no display can be seen unless you look VERY close. They can be repaired, but with parts and labor costs compared to the price drops of new LCD's most folks opt to upgrade....In short, get a written estimate for repair costs, if you choose to go that route. For less than 200 dollars you can get a NEW 23 inch LCD with DVI, HDMI and AGP interface with a full high definition display that supports the latest Blu-ray devices for FHD/HD true digital content.
Hope the information i have provided you is helpful...

SOURCE: lg flatron l1730 no power on screen

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed LG and other monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

SOURCE: Hi. I have an HP a6115uk

Hi,

Welcome to Fixya. It seems that the issue is not caused by the monitor or the video cable. You can determine if this is caused by the motherboard by using the onboard display if the motherboard has any. If you want to use the onboard graphic just remove the video card and it will automatically use the onboard graphic. If this wont still be able to fix the issue the problem that you have is the motherboard itself.

If you have questions please let me know.Thanks

SOURCE: HP vs17 (PK657AA) problem: the image is displayed for 3 seconds

first try entering VGA mode in the startup menu. u can get the startup menu by pressing the F8 key immediately after the POST screen. if the screen stabilizes try changing the resolution to 1024 by 768 which should work in normal mode. if that doesnt work then the monitors internal bulbs may be burnt. an electrician may fix this problem for you.

Just press your finger anywhere on the screen and it will turn darker around that spot.
You obviously warped the outside lid of your laptop. See if you can take the lid and the LCD apart and straighten the lid to relief the LCD-pressure from behind (literally...)

SOURCE: hp SH249 LCD monitor is flashing

You probably have failed capacitors inside the monitor. It's apparently a common problem that has happened to my Samsung.
Symptoms are flashing video for several seconds before becoming steady on. I am in the process of having new capacitors shipped to me so that I can repair it.
Try http://lcdalternatives.com/
They sell repair kits specific to monitors.
I did not see your specific monitor listed, but I did see the 2410. Send them an email and ask them if their kit for the 2410 will work, if not, then they can make a kit for you. You will have to identify some parts for them, but it should fix the problem and you won't have to buy a new monitor. For some reason they did not respond by phone.
Apparently due to corporate espionage, some companies made inferior capacitors for a time. It's called the "capacitor plague".

How many months or years of your monitor that you are using? Do you check the outlet, cables? It's seems that your monitor has a problem because i read your observation that your monitor seems to be replace a new one. That's the monitor's problem.

The image is blinking.I can only see what's on the screen for a fraction of a second and then it blinks. The image is also very dull


Looks like a bad CCFL lamp, not a user replaceable part. You could have it checked by a local repair shop. If it's the lamp, the while LCD panel needs to be replaced.

Time for a new monitor?

Hp flat panel monitor comes on shows logon and then blank screen


Ok, another words, monitor powers up for few seconds and shuts down by itself. If green LED on the front panel turns off as well or stays on?
If stays on, then inverter turns into protection mode because of old backlight lamps.
If it turns off in same time with an image on the screen, then there are some bad electrolytic capacitors in the power supply.

Dell - 17" flat screen


This sounds like the back light is gone on the monitir... to check this look very close at the monitor whet the PC has booted, if you see a VERY dim image on screen then it suggests that the back light is gone.

Many monitors hace a 3 year warranty so I would try a warranty claim before throwing it away
