Samsung SyncMaster 940MW will not turn on

Where do I send it for repair. I need to know how much it will cost to fix, versus trashing it and getting something different.

    My monitor is getting increasingly hard to turn on. The green power light just blinks and doesn't stay on. It happens with both the remote and the power button on the monitor. Today it took 5 or 6 tries before it turned on. I called Samsung since my monitor is still under the 3 yr warranty. First they said they would replace it with a refurbished one ( under 1 yr, they replace with a new one), then said no replacement was available so they would have to repair it, with a 7-14 day turn around time, and are emailing me a no charge shipping label. Luckily, I kept the original box for shipping. Not sure how I'm going to manage with no monitor in the meantime!

    The power indictor light blinks on and off and takes a very very very long time before it actually starts up. It's getting progressively worse.

There are broken/exploded capacitors on the power plate, it is a 5 Minute job to replace them.

Here is a repair guide showing how to dis-assemble the unit and repair the power supply, this is the most common issue with this unit.

If you don't want to do the repair yourself then you can get it repaired here:

Most new LCD tv and monitors color,brightness,vert.hold, horz.hold,resolution, ect., are all controlled by a single programmed EEPROM, that costs more to replace than a new monitor/tv. You pay for the programming, not the chip.

Your monitor has symptoms of power supply failure. The age of the monitor and the cost of repair will influence your decision whether to repair it or dump it

Screen stays on approx 5sec than does black. turn off and than back on for another 5 sec. is it dying?

Simple answer is...yes.
Your monitor is suffering from "capacitor deterioration" whereas the caps can't hold or maintain the voltage or charge as they were originally designed to do.

If this was a big tv, then I would say that it might be cheaper to have it fixed, but the repair costs for a monitor with this type problem usually costs as much, and some times quite a bit more than the cost of a new one.

The reson the costs are so high is the capacitors that they use in tv's and monitors aren't like the ones at your local electronics store.

They are high voltage/amperage capacitors, and usually have to be special ordered from Taiwan, or someplace like that.

The actual part might only have a cost of say $5.00, but after international shipping and manufacturing costs, as well as tarriffs and taxes levied by different countries that the parts would go through, then the final cost may be closer to $50.00 per capacitor.

And that's not even counting the cost of labor to do the repair work.

If you really want to get it fixed, then I would take the monitor to Fry's or BestBuy.

Both companies have specially trained service techs for just this repair.

Have them give you an estimate as to what the repair cost is, and you may want to go look at prices for new monitors, just to see what the difference in price is between the repair cost vs. the replacement cost.

I hope that this helps you out, and good luck.

I doubt you will find a circuit diagram for a monitor. They are NOT user servicable.
IF you want it repaired, take it to a repair shop. IF you cant understand anything, just get a new monitor.
It would cost you more buying the equipment to diagnose the faulty part, then buying the parts IF you can buy them. A new monitor can be had for about £90, it could cost you alot more to try and fix it

I am geeting lines in the center

I try a different video cable. Sometimes a wire goes bad or pin gets bent.

The more likely cause is simply a bad monitor. If it is still under hardware warranty I would say look into getting a replacement. Depending on how expensive a new one is versus how much a repair costs I would explorer those options. There is nothing that can be done in software though, it is a hardware issue.

HP F1703 Screen goes black within seconds of startup

That is either the backlight or its power supply.

This is a bit tricky as you can get it fixed under warrenty but they will likely ask you to send back the entire computer not just the monitor. It is also something that you could fix or several shops could but the repair cost really isn't much less than a new monitor. You are not stuck using an HP monitor so anything will work and you can get quite a lot bigger or better for about $120 and up. Repair cost is going to be $80-$100 so as you can see for just a few dollars more you have a new warrentied monitor.
