Unplug the tv for 5 minutes, then try this. Keep holding the VOL+ and CH- buttons down while you plug the tv cord back into the wall ac outlet till you get sound and picture for a second or two. You should be able to turn the tv on and off with the power button now. Next turn the power button off and unplug the tv for a few seconds and then plug it back in and turn the power button back on. Watch the screen and see if the sound and picture comes on, best to check in a dark room to see better, if sound stays on and picture comes on a few seconds and back off you have a bad CCFL backlight lamp in the LCD panel. This tv hads (10) CCFL lamps part # RLMPLA029WJN1 cost $15.93 at
www.partstore.com or $19.49 at
www.encompassparts.com in it and if one is burned out it will not let the tv picture be powered on till it is replaced. To check and replace the CCFL lamp you will have to unplug the ac cord from the tv back and remove 10 screws holding the back on. With back removed unplug the wire plug on the power button circuit at top left side of the black LCD screen trim, remove 4 screws holding the top of black trim, lay speakers off it, and release trim clips, (4) at top and (2) at bottom with a flat screw driver, and lower the trim to unclip the LED circuit board at bottom left side on the trim. With trim removed, at top of LCD panel remove the (2) PC ribbon wire clips with thumb nail by lifting up on it to release the flat PC ribbon wire. Lay the tv back on a soft pillow with screen up, and look on the LCD panel front for and remove the (10) silver screws 1/2" long with an arrow mark beside them. Do not remove any gold colored screws or any without marks. The LCD panel screen can now be lifted off, lift the backlight plastic thin sheeting and thick sheet off to see the CCFL lamps. Plug the ac cord back into the power supply inverter circuit board and plug the power button plug wire back in its circuit board on the LCD black trim panel, and power the tv on while looking at the CCFL lamps. If the lamp is dim or burned out, take the (2) white plastic covers off the ends of the lamps with a flat screw driver and unclip the lamp to replace it, Check the lamp socket part # QSOCFA003WJZZ by putting a good lamp in it and if it lights up the sockets are good and the bad lamp was the problem. If all the CCFL lamps do not light up, unclip the top lamps and move them to differant sockets to the center and the center lamps to the top, if the lamps do not light up, then it is a bad power supply inverter circuit board the ac cord plugs into, part # RUNTKA448WJQZ , cost about $160.00 for new one or less if you buy a used one on
www.ebay.com , replace it and the tv should work ok then.
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.
Cheers,

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.
