Monitors goes black - Hyundai Q17

problem related to lcd lamp supply
just replace the power supply(called inverter board) connected to the lcd panel lamp

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

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

Cheaper to replace than repair

Hello,

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 www.ccl-la.com/badcaps.htm 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.

The first thing to check is the power supply to the monitor. Mine went a while ago, black screen nothing happening, turns out it was just the power supply. A quick search on your favourite browser will probably turn up a supplier, I found one that just makes monitor power supplies, so it must be a common problem!

If you have a meter test the power coming into the monitor, or if you're unsure put it to your ear when its plugged in, you should hear a faint buzz which means its working. Also check for any breaks in the cable and/or if there is a fuse in the plug which might have blown**

**If a fuse has blown, it might point to another problem, but at least it's a starting point

hyundai will not repair this however a electronic service center aka tv repair may. I can do it as most likely is it several capacitors that have blown. Hyundai is also a little picky to open they are assembled very well actually compared to other monitors (they are difficult to open up) let me know what you would liek to do.

the power button board is electronically fried you need a new one

Ok? first what you need to do is to hibernate your computer. You can do that by pressing the power button as long as you need for the computer to turn off. Then you turn your computer back on and press the power button ON THE MONITOR twice but you MUST do this really fast. Then what you need to do is to find a circuit breaker on the back of your computer. switch it to the off position then turn it back on. Then turn your computer on. This should fix your problem.

Hi i have the same problem i think it is the power board you can buy these on ebay for about £200 i havent botherd as yet as i might just buy another tv as ive had no end of trouble with it dont think i would ever buy a hyundai tv again!!
