    My Samsung 173v flat panel monitor also does not come on for a half an hour and longer at times. (sometimes I get lucky but extremely rarely, there's usually a long wait for it to decide to operate) It does the same thing regardless of which computer I hook it up to. The cables are not loose and I'm running several other flat panels which don't have this problem. Also I'm experienced with computers. My hope would be that it's a driver problem but my guess is that it's a physical/mechanical issue with the 173v. This was a new retail purchase. I plan to contact Samsung. -was just googling to see how many others have experienced this.

    G'day, my 173V has similar symptoms, which appears to be a problem with the internal power supply. The failure is intermittent but is progressively getting worse as the failure is more frequent and longer duration. In my case the power light goes out when the screen blanks and then returns. The monitor resets but the power light goes out again before or soon after the picture returns. I also hear a click each time the screen resets, which is why I surmise this to be a power-supply issue. I have changed the cord and opened the monitor and checked internal connections and soldering of the AC pins to the power supply. Nothing loose and no sign of anything burnt. I am now looking at a replacement power-card.

    Hi, I'm from Brazil and I've got a similar problem. Each time I turn the computer off the Sansung 173v seens to go to a "wait mode", that means, the green lights flashes half a second. When I turn the computer on again, the monitor does not come back to life, that is, it does do go to a "awake mode" or something. Sometimes, removing the cable from the backside of the computer, waiting for the mensage "no RGB input" and then put the cable back again into the computer resolves the problem, at least if I do not turn the computer off again. But sometimes, not even taking the cable out resolves the situation. What should I do???... Guilherme

    Has anyone successfully found a place to find a replacement power card? I think they call them power inverter boards. I've been searching for some time without any avail. I'm based in Australia but happy to import it if the price is right.

    no solution here but please do
    add me to the list! My Samsung 173v flat panel monitor screen display which was also purchased new at retail does not show an image for varying durations: 10 minutes (if I'm lucky) or more commonly 30 minutes or several hours. Eventually it comes on though it's been 6 hours today (1/26/09) and I've got nothing. It's extremely annoying and pathetic. A while back I switched computers to make sure it was indeed the monitor. Of course the problem persisted. I haven't opened it up and with panel prices being significantly cheaper these days, I wouldn't spend much to fix it. Actually, Samsung should fix it since this is more than likely a manufacturing defect. I highly doubt that it's a driver issue based on my experience and others listed here. My other flat panels all work fine including a $50 Hyundai from a flea market! For me, this is just another reminder to not buy items new at retail. I'll call Samsung and see what they say but there's no way I'm spending my dough to ship this dog. I'm sure it's past their warranty date as well. I leave it plugged in and on all the time and for a while that seemed to work or help but not these days. I'll try plugging/unplugging the mon cable or hitting it with a wiffle ball bat. LOL. but my expectations are extremely low.

I've had a similar problem with my 173v monitor since I bought it a few years ago. When I start my computer, Mac or PC (I've connected it to both), the screen remains black and the green power light flickers once a second, almost like it's twitching - it's different from the blink it makes when the computer isn't turned on but the monitor is. Like kronem, I have to unplug the line from the monitor to the computer, wait for the monitor to register no input, and then plug the monitor in again before it displays anything. I've never figured out a way around the problem - I hate it!

The monitor comes on and then goes black.

Sounds like your LCD panel lamps are shutting down, this could be either due bad tubes, or more likely lamp driver power supply is faulty.

Monitor Goes black, or flickers on and off

The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.
