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