Question about Hyundai ImageQuest L70S 17" LCD Monitor

1 Answer

I have a Hyundai Image Quest L70S, the screen goes blank

I have a Hyundai Image Quest L70S, when I press the on button the screen will display for about 1 second and then goes blank. I have rebooted the computer and the screen will flash on and then go blank. I have unplugged the monitor (for 2 hours) and still get the same results.

    The backlight inverter is bad. I received two Hyundai L70s monitors in the same condition from my employer and I've disassembled one of them. Unfortunately, the inverter is built into the power supply board and I haven't been able to find a source for the board online. I'm wondering if I might be able to figure out what component(s) is/are bad. The board has a large 68uf 400V capacitor that seems to show open on my multimeter no matter how I read it. On a Sceptre 15" I have (which has a different power supply issue), the same 68uf capacitor reads an incrementing value in OHMs and a decrementing value in VOLTs (which I understand is supposed to be normal).

Power button flickers green and no display


It can be that it is not getting the signal from the PC, or it detects short circuits so it goes into shutdown and try to restart, or failed power supply due to bad caps. Try it on another PC and also check the VGA cable first. If it still does not work and you want to DIY repair, then please read below and look at alot of pictures so you will know what to look for inside.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Power on Green Light Blinks but no picture. Will not turn on. Hyundai Image Quest L705


bwpvemail, The units "switch-mode-power-supply" may be in shutdown mode. A tech will need to evaluate. Check to see if Hyundai has a refurbished swapout+cash program?? It's that or trade in for new wide screen, so the tech in the store "back-room" can possibly put $8 in new filter capacitors in your unit and with a little luck will have a 17" L70s for 1-2 more years use. 12fixlouie
