Open the case, remove the power board and visually look for bulging caps. I replaced 3 on mine and now its prefect.

Flickering screen and wont light up. I tried hooking it up to another computer changed power cords and cables to no avail.


You tested the screen on another computer and the fault is same on both computers. This means the Samsung LCD screen is faulty, this fault could be a faulty inverter board that supplies high voltage to the CCFL lamp or the CCFL lamp is faulty.
If you want to fix it yourself then parts maybe available from LCD Parts.

Acer desktop PC locked up and now won't turn off or boot up


Hello,

I've seen a similar issue on Acer Veriton 7900. When you unplug the power chord while the machine is still running the BIOS/CMOS gets bugged up. If your PC doesn't have a 3 year warranty you can clear the CMOS/BIOS. To do this, note the following...

1.) Unplug the power cord

2.) Remove the CMOS battery from the unit

[OPTIONAL] move the jumper on the mainboard to the 'clear position' It should be indicated on your mainboard.After 30 seconds move jumper back on original position

3.) Wait for 30 seconds

4.) Place CMOS battery back into its position

5.) Reconnect the power cord and attempt to power on the unit.

Monitor cold start issue only as #2 monitor


The start up problem is common and will only get worse. Call Samsung as these monitors have a 3-year warranty. No receipt? They will accept your word regarding your purchase. I have two that failed exactly the same way. I called 1-800-SAMSUNG and they gave me the choice of an exchange pair sent directly to my house (requiring a temporary credit card deposit) or by having the exchange pair sent to the UPS store where I would swap out my bad units. No receipt. They merely asked me when I purchased it so they could have it for their records. Manufacture dates such as your (March '06) and a purchase of September '06 are not far fetched at all. .

Samsung 931B monitor - shadowing


I have the same monitor, and twice I've experienced this exact problem. In my case, the video connectors have relaxed. If I wiggle the cable, I can make it better or worse, so it's time to disconnect, reseat. I don't know if it will work for you, but it's free!

SyncNaster 931B


take a soft cloth (type used for cleaning glasses) and moisten it with a small amount of water on one corner.

gently wipe the wet portion of the cloth across the screen (if you have any weak alcohol based cleaners you can try it. I have used hand sanitizer before on my 931b w/out problems, I wouldn't use any extremely strong liquid cleaners though).

Use the dry part of the cloth to wipe the area dry, then move to another part of the monitor once you are satisfied.

HP MX 75 CRT monitor just quit working. No light on the on button.


...strictly as, at at best. a long shot: according to a post I just read somewhere online about this HP MX 75, pressing AND HOLDING the + button on the monitor front and at the same time turning the monitor on and off repeatedly, may fix problems with this monitor.
