Monitors goes black - Hyundai Q17

Hello, My monitor (Hyundai Imagequest Q17, 2 years old) remains black after I turn it on. The green power light is showing. And if I look very closely at the monitor, I can see whatever is on the screen, but all is dark. Could it be possible that it is the bulb which died ? What over possibility have I ? Thanks for the help Nicolas CJ

Re: Monitors goes black - Hyundai Q17

I can verify after opening my monitor up as well that the solution posted by W_Steenhuis does in fact work. The power cord itself didn't have an adapter, but the power "adapter" was in the base of the monitor itself. The big circuit on that was where I found a diode and resister side by side that were badly burnt. I basically put some solder down each of the connections to the board to broaden the overall connection of each just to make sure that there were no gaps. Now my monitor works :)
Thanks again, W_Steenhuis.

Re: Monitors goes black - Hyundai Q17

I had the same problem some time ago.
After dismateling the power-supply unit it apeared that there was en crack in a solderjoint at one of the power transistors. This transistor has 3 legs (TO220 I believe), from which the middle leg had a solder crack, probebly due to thermal stress. Just resolder and it worked again....
Its worth a try I think.

Succes,  Wim Steenhuis.

Re: Monitors goes black - Hyundai Q17

Thanks. I sent the monitor to Hyundai as it was under guarantee. After a 3-months-wait (!!) it came back with a new bulb.

Thanks !

My hyundai imagequest l70n lcd monitor started to started to make a high pitched noise and the screen went black but the green light stayed on but now i plug it in and nothing happens no picture and no...

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:
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

Hyundai b90a monitor screen is blank... the power light goes briefly green, then goes to yellow standby... even when rebooted.


It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and -connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $45 plus shipping. If your problem is not the capacitors then it would be the backlights and that is much more difficult to replace.

I hope this helps, if so please rate my solution.

Hyundai imagequest Q17 montior problem

ontherhodes5, Your monitor will probably need servicing for one or both power supplys in the unit. Yes, If you can get a new oem Switch-mode-power-supply/inverter board you might get it working. I suspect that it (smps) can't supply the voltages needed by the logic-interface board- therefore no digital data can be processed for display on the screen, which should be white-bright but now only gray. (dim) because the 1000v ac from inverter circuit is also missing 10to40% of it's output. Your best bet will be to find out if Hundai can do a repair/swapout. You send yours+$40 to $90 and they send you a Refurbished same model with new CCF tubes, Inverter board, smps board. It seems that sooner or later these lcd ccf (cold cathode fluorescent tube backlights) will need servicing. Don't feel bad about this monitor. There are about, (guess only) 2500 more of all makes and models with similar power supply problems out there. To see whats inside a lcd search YOUTUBE for vids of servicing or repair of lcd screens or similar.. also www ??? or or visit run by a Jestine Yong. Ignore the sales pitch and just look fyi. hope this was of some help. drop me a note if possible. I'm louie12fix on fixya or lmistyrel@ BYE

Screen does not start (switch on)

Sounds like a mode issue. Make sure you have the pc set to a compatible mode for the monitor. You may also want to double check the vga cable is firmly set in the monitor and pc.
