Question about Sanyo Computers & Internet
We purchased our Sanyo monitor about 8 months ago. Today, it has been turning off by itself after being on for a few seconds. When we turn it back on, it goes off again in a few seconds and repeats itself. It's similiar to a screen saver coming on in a few seconds. I'm not sure what is causing this.
Please let me know if there is anything I may need to check OR is it defected?

The problem with this monitor is a leaking capacitor on the power supply board. It is the middle one at the top in a row of three. The value is 10V 1000uf. Common problem for these.
Remove 4 screws from back of display. The case can be popped apart with a small flat putty knife at different points along the two seams. Three latches on each side and two at top and bottom. Push and twist at the latch points. There is a metal cover over the two boards. Power supply board to left. Screws and plugs can be romved. Unsolder Capacitor and replace. Radio Shack probably has them. Maybe a couple bucks. Be sure the power has been off for a while. These also have problems with the button board and corrosion at ribbon cable.

When it goes black, does the power buton stay green or is it orange? If it's orange, the power supply/inverter is your main culprit. If the power button stays green, it sounds like the backlight for the display is bad. Either way, unless you have parts for the same monitor laying around to swap out, you're due for a new monitor. The good news- with the economy in the tank, you can search online and find some reputable vendors selling nicely sized screens for less than $100! Heck, I've even seen a 22" for $129 (once but it was there).

i just finished repairing a 20 inch acer monitor that had the same issue.... you have to take it apart and examine the power supply side of the monitor. there are capacitors that go bad on that board. you can tell be feeling the tops of them... the feel rounded. replace the capacitors and put it back together and it will work fine

I had the same problem with my two LCM-19W4 monitors. Both failed within two months of each other. Radio Shack stocks 220uF 35V capacitors that work fine for this. You have to pay $1.49 ea though.

If you turn the monitor off then about 1020 sec turn it back on and have a picture for five sec again it sound like the power supply in the monitor. but if that did not solve the problem, the picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault and will need to be replace.
I advice you replace the picture board on the screen of your monitor to solve the problem of the blank screen.
