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

My Hyundai B70A's screen is blank grey. I've changed the power supply, the vga cord and the video card with no change. What should I do now?


If you get just the grey glowing screen (as shown in my guide), it means that the T-CON board on the LCD panel is not getting the 5 or 12vdc from the logic board or it has blown fuse on the T-CON board due to shorts circuits, not much you can do but replacing the LCD panel.

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.

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.
