| 1248947 | 2011-12-16 19:10:00 | My main desktop monitor (working fine Yesterday!) has decided this morning that the backlight is not going to work. How much would it be to fix this if i don't get it going again? (could it be the cold weather fiddling with it?) It's a Samsung SyncMaster720n. and it's 17". |

| 1248948 | 2011-12-16 19:37:00 | Same thing happened to one of mine. Last time I turned it on, it took like 10 times to turn the thing on. I think the power inverter was buggered. In the end I biffed it | Speedy Gonzales (78) | ||
| 1248949 | 2011-12-16 19:57:00 | Depends what died, the Cold cathode tube or the inverter. Depending on time/skill/money you can find out the model of the LCD panel and replace that, find the cathode tube part number and replace that or replace inverter. Some cathode tube replacements will come with new inverters. All failing sell it. me and a mate use damaged (that still have a good LCD) because we strip them down for our MT table. Water damage is good since the diffuser layers bubble but we dont need them, we put in a Rear DI layer. Get rid of all the backlight/DI layers and just use the panel. Only thing is we need working hardware that goes with it (basically the LCD's "motherboard", all its control circuits etc) |

| 1248951 | 2011-12-17 01:54:00 | Probably cheaper and certainly quicker to just replace it. They are fairly inexpensive nowadays. | CliveM (6007) | ||
| 1248952 | 2011-12-17 02:40:00 | hard to say, had a laptop screen repaired once and it was $220. Probably not worth it for a monitor........ | pctek (84) | ||
| 1248953 | 2011-12-17 07:24:00 | I've personally repaired a bunch of HPs (BenQ boards) for about $5.00 each. Depends on what failed however. The HPs I've been able to fix had visibly bad caps and roasted picofuses (baked right off the board in one case... no solder left on it, and the printed circiut peeling away from the heating) This problem is typically near the top of the board, where caps have been placed too close to heat sinks. Stains on the board may also reveal blown caps. Odds are the guts of your monitor are BenQ as well. |

| 1248954 | 2011-12-17 07:44:00 | I got a 17" screen (LCD) for $60 a year ago. Keep that in mind when looking for parts. | icow (15313) | ||
| 1248955 | 2011-12-17 09:18:00 | My main desktop monitor (working fine Yesterday!) has decided this morning that the backlight is not going to work. How much would it be to fix this if i don't get it going again? (could it be the cold weather fiddling with it?) It's a Samsung SyncMaster720n. and it's 17". Can you still see a picture if you shine a torch on it for example or is the thing totally dead? According to this: www.badcaps.net that model's PSU uses Su'scon capacitors which are rubbish. Could be part of the problem... |
