Sounds like it may be your power supply. Try swapping it for one that you know works being careful to plug everything back as it was.

Lg w2753v monitor shuts off


Make sure the power cable is firmly plugged into the monitor and into the wall. If so, you may have either a marginal power-supply to the monitor or the monitor electronics may be failing.

If there is a power-brick (adapter) on the power cord for the monitor, make sure the wires going in-to and out-of that are not loose or damaged. Consider a new power cord before condemning the monitor.

MAG innovision LT-926W 900W problem! After I turn on my computer, the screen immediately begins to flash and then goes black. The power is still on thought and so is my computer. If I take a flash light...


this means your power inverter inside the monitor is dead. This little gizmo lights up the monitor backlight. They dont fail all at once, but slowly die and give problems like you describe, you can order these online for your monitor , or find one on ebay for under 30 dollars, but unfortunately there is no fix, other than replacing the inverter. sorry. Please use the thumbs up rating if you find my answer helpful, albeit bad news. Take care. .

HP DV928US When battery in or charger plugged in


fails battery out so leave it out they love to short.
so when it fails test 2 is, hit the F10 or ESC key promptee
went it fails to boot, check BIOS key first, if BIOS fails.
be more clear.
what does it do when it wont turn on.
BIOS dead. screen 100% dead, and not even text
BIOS works even with HDD and DVD drive pulled.
that is the acid test on PCs.
the screen must say, hit F10? or ESC to enter setup, means HP BIOS. it must or power is no good. get a new power pack
the shut down tell me lost power, that can be the power pack 19vdc
or the jack at the mobo if failing to said pack.
try side pressure on that jack if at anytime the power button fails.

it self shuts down, I got that but lets fix , cant boot first.
that is how to fix this.
power on failures, are you saying the power key fails. some times
and the fan does not run every time.?
Also,
this old LT uses CCFL back lamps.
that love to fail. so when it shut down did the fan die.
did the HDD stop spinning ear to bottom? if not the CCFL is failing.
using and external monitor proves this every time,
do the flash light trick?

My DELL flatcreen just went blank and is now flashing yellow light, won't turn on


Check and make sure your connections on the back of the PC are snug...and make sure you have a good connection at the back of the monitor.
Flashing light...is loss of signal.
Good Luck,
Mike

HP mx 70 Monitor


This is a problem usually with the Power Supply unit inside the Monitor. Often it is the Electrolytic Capacitors arround the Heatsink area. They dry out and go faulty.. It is generally a job for the "Shop" I get them all the time... But in saying that intermittent faults are the hardest to find.. If you do take it to a shop, ensure you get a firm "Quote" and explanation B4 proceeding.
