B24teddy, This seems to be a power supply problem. Some can be repaired (DIY) for $20 or less. $35 to $70 if contracting out the work. More if replacement circuit board is needed. From your problem description I get the feeling that your monitor "works" and will display an image or data on the screen. Your description of your monitor symptom is what is known as "black" screen or "black&blank" screen. If you know the pc has finished booting and is displaying the WIN-desktop, point a bright flashlight 1 inch from the black lcd panel and tell me if you see a faint image of your desktop. If nothing is seen=full shutdown of SMPS power supply. If icons are seen=partial shutdown only! If you read some of my older responses to owners of black screen lcd's in my FIXYA profile (pages 10 up) you will understand the problem and how some owners who are handy with a soldering pencil (iron) restore their units back to life. Yes, your's has a good chance of being fixed. Just spend an hour reading in my fixya file and then decide what you will do.

Our CAL232 TV will not turn on. When pressing the power button, you can see a red light and a green light, but the screen doesn't start up as normal. The TV then tries again after about 20 seconds, but...


Hello,

My LOEWE CAL 232 will not power up. When the power button is pressed, the monitor turns on, with the LOEWE on the monitor, then the TV continues with the previous activity (antenna, DVD, VCR etc.). Now all that happens is

1. the red light comes on

2.after about 1 second the green light turns on for about 12 seconds

3. the the green light turns off for about 1 second

4. then the green light turns on again for about 12 seconds

and this continues until the power button is pressed to turn the TV off. During this time, the monitor does not turn on and the only sound I hear seems to eminate from the power button.

Any thoughts?

The monitor will not turn on. When power button


First--was it working?
Did it suddenly stop?
When you see the LG logo, then it goes away, does the power light turn from green to amber? Sounds like that doesn't happen.
So--if you are getting a signal, you should see something.
If there is no signal, then the power light should change from green to orange.
With no lights at all, I suspect a faulty monitor.

Acer monitor AL1706 Power On problem


You are more likely to have bad capacitors problem in the power supply, inverter circuits. I would look for bad caps first. Look at some of the sample here: http://s807.photobucket.com/home/budm/allalbums

Power light blinking yellow after sitting a while


Unplug computer, disconnect all usb/monitor/internet, open it, hold power button until green led on the inside on the motherboard turns off, pop out the BIOS battery (looks like a big watch battery and use a small flathead screwdriver to depress the spring lock on one side), plug in computer, hold power button for about 20 seconds (must reset BIOS or something), let up on power button, wait 10 seconds and push power button. The computer should turn on. Wait for it until activity seems stable (1 min. or so). Push powerbutton to shut off.

If this has worked you have proven that it's not the power supply (it turned on).

Go buy a new battery (CR2032 3 volt). Unplug computer, open it, hold power button until green led on the inside on the motherboard turns off, pop in new battery, plug in (you should notice the power button blinking amber again), hold power button until it stops blinking (about 20 sec....again must reset BIOS or something), wait 10 sec., push power button. the computer should turn on. Wait for it until activity seems stabe (1 min. or so). Push powerbutton to shut off.

Now, close case, plug in all usb/monitor/internet/etc. Power up computer. You'll get an internal floppy drive error. Push F2 (maybe F1) to get into the BIOS settings and go to "drives" and turn off the internal floppy. Save and exit. The computer should boot properly now.

This seems to be a big problem with the e510, my theory is that this one small battery is the root of most of these failures (as these computers usually fail after 1-2 years), not the power supply or the motherboard (heck, when you replace the motherboard it comes with a new one of these batteries...a several hundred dollar piece of hardware, with a $5 battery that will actually fix it).

Monitor doesnt come on , but the power light goes from amber to green. then comes on after 20-30mins maybe.


Maybe update your display drivers. PC appears to be slow.
Make sure you don't have a bunch of apps that auto start.
Do you hibenate your PC?
Same issue if you connect monitor to another PC?
If issue follows you to a different PC it says monitor. If it doesn't it says the first PC (that monitor is currently connected to) had a cpu/memory or a driver issue.

Good luck
