Problem with powerup for my screen

If I could get the screen to work there are no problems unit functions great. When I turn off my computer and the screen goes into power save mode it doesnt come back on. The power light stays yellow (which means its in power save). I have to unplug the unit for a 30-40 secs and then plug it back. Doing this sometimes doesnt help. some of the time I have to plug and unplug about 100 times to get it to work. I think it might be the power unit but who knows. When I use a different moniter i dont have any problems. If you have any info please e-mail at

When the screen turns black again take a flashlight and shine it in the bottom left hand corner where the Windows Start button is located. If you can see a faint image then your back light is failing. If that?s not the case the next step would be to attach another monitor to your computer to see if the problem disappears. If it does that points to the monitor, if it doesn?t then we need to take a look at the computer itself. Let us know what you find out and please don?t forget to rate this posting.

The problem is with power inverter, usually the capacitors go bad and need to changed, they might be bulged and or leaking. Very cheap fix, less than a buck apiece and an hour with a solder iron. Google it to find more info.

It's a common problem with sony hs75p
the problem is with the power board's transistor in the monitor

people might try some stuff and may get some results, but trust me it's all luck...

i had the same problem, so i gave my monitor for repairs as it was under warranty and the culprit was the power board (sony calls it the 'A' board). The only problem is u need to have patience as u are dealing with sony here >_>.... i mean, i got my monitor back, but after 2 tries and with many dead pixels and analog signal being greenish...well atleast the DVI port worked fine >.>, which they said wasn't their fault ( i was like...riiiight, so the dead pixels generated all by themselves, huh?..btw if u are wondering...before giving my monitor...they checked the monitor and it's written in the receipt that the monitor had no dead pixels).... so dont be surprised if ur monitor comes up with another problem, after giving ur monitor for repairs to sony >.>

in any case it's 'A' board problem

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

WYSE 50 beeps at turn on, but no data on screen. Seem to recall that you could hold down some keys when powering on, but do not recall which ones.

On powerup, you can get to options screens by pressing one of the F-keys. It varies between computers, but it's usually either F2, F8, or F12. If in doubt, try all of them until you get a menu screen, then go from there. The beep at turn-on is an indicator that something isn't hooked up right, usually, so recheck all your connections, then take it from there. If you still have your manual, it will tell you the powerup options, and how to access them. Good luck!.

Can not get the thing out of demo mode read instructions no luck.

Look for the function button. Once found (on unit or remote), turn off the power. press and hold the function button until the units sub menu pops up. use this screen to set time and other options. one of the options is to turn of demo mode. At least that used to be how pioneer did it.

Blank screen - appears to be dead

If the screen is completely black, your screen may indeed be dead. There are a few solutions you can try before throwing in the towel though.

1) Test the monitor on another PC if you can.
2) Make sure the contrast, and brightness aren't turned all the way down.
3) Make sure the graphics card in your PC is functional. You can easily test this by connecting a known working monitor to your computer.

If these steps do not resolve the issue, and your graphics card is in good working order, you indeed have a dead monitor on your hands. It may be cheaper to buy a new monitor, than to have that one serviced.

Samsung GH19LS LCD Monitor wont display computer signals

You should have received two cables with the monitor. One is for VGA and plugs into you video card or computer board . The second one is for DVI digidal video and if you have that cable it plugs into the square connector. Then if you look into your monitor manual or quick setup sheet it will tell you how to connect and set the monitor to either VGA or Digital. I'm sure that is what has to be set. Don't hook up both cables to the monitor and computer. Only use the one. Digital gives you a better picture if your computer has that function. Hope this is helpful. Bud

this problem many caused by bad inverter. If invertes not function, it won't feed back a good signal to tell mainboard that LCD backlight is working, so the mainboard turn off the display.

To fix this problem, it is need a qualify technician and inverter's part.
Send it to LG, they will not charge you expensive. LG have a great service.

Samsung SyncMaster 710N 17" LCD Monitor - Grey screen

Does this unit have an external power supply (wall wart)? If so, substitute a known good one of similar specs. If the original is 12 Volts/1.2 Amps, find a 12-15 Volt/1.2 or greater Amp. DO NOT go over the voltage more than about 15-20%. DO NOT go under the current rating less than 90% for just long enough to see if it works. Be sure the connector fits PERFECTLY!!! Some will appear to fit but will be loose. Do not under any conditions replace a DC supply with an AC one or vice-versa.
