Question about KDS Radius RAD-7c 17" Flat Panel LCD Monitor

1 Answer

KDS radius 17"LCD RAD-7C shuts off during boot and won't come back on (mostly)

I have been using the same 2 KDS monitors side by side, on my pc for several years. About a year ago I began having a problem with one of them. I would turn on the pc, and both monitors. The "bad" monitor would light up as normal at this point. As the boot continued, and the screen went black (normal in booting) it would go into standby (yellow led), but would not come back on. Attempting to "reboot" the monitor didn't work. I have tried swapping the monitors to verify it is the monitor, and it is. For a while I simply waited until the computer was already booted to turn it on. Eventually I had to use a line power switch to turn it on. This got worse until now it does not come on at all even though the led is on, and green, the screen is black with no light at all. I now have the thing apart, and I suspect a power supply capacitor is the problem, but I don't know which cap to check. Checking them in circuit is not reliable, and taking them all out would probably ruin the circuit board. Part numbers on the board are typically TC1... TC19 etc. for caps. Any advice, drawings, or info would be apreciated. Thanks in advance, Mike, AKA pcrider

I am having the same problem and this seems to be very similar to the problem these users are having but that is a different screen. So I was hoping someone would have more info on this specific monitor. I am seeing no budging capacitors on my boards.

Hello, I have a Kds Radius RAD-7C monitor and the original power supply is no longer working. I have a universal power supply with a range from 15 to 24 volt and 6 amp, my question is, can I use this for...

6A is OK, HIGHER CURRENT is OK but not higher voltage, the main key is that the pwoer supply MUST be REGULATED power supply. Does it say that on the universal power supply that you have?

mcdevito75 here, You can try this, 1 of the buttons should say AUTO presss this button and the monitor will automatically adjust, and Or press the MENU button and see if there"s a brightness feature, I believe there is, you can use the little arrows on your monitor within the MENU options. First try the AUTO.

Lost the instructions - don't know how to adjust color and resolution - what the buttons on side are for. Actually this is a RAD-7c, model 780 mfd Jan 2003, probably starting to fail.

The buttons on the side panel is are the ones you need to do the color adjustment and resolution. One of those buttons is the Menu, two of those buttons are used for selecting the options from the menu and maybe another pair of buttons to adjust the selected option to increase or decrease.

KDS product 17s, model 700p. I am getting the follwing message "mode not supported H 82.8khz V77.7hz" whenever I boot the computer. I cannot escape from the message. The computer it is attached to is...

Start in SAFE mode (press F8 wile booting) and choose SAFE mode from the menu to see if it works in Windows DEFAULT setting. Then reboot and reset to 32Bit, and 78Hz max.

My guess is that MSoft pushed a patch or SP to your box and IT replaced the dll your monitor was using.

Good Luck!
Let me know if this fixes it

First try it with another computer to verify monitor vs computer. If it is the nonitor, it's probably not something she can handle. Gary(Honkity Hank)
