Help with CPD-300SF monitor does not detect sync from cable?
I have this monitor, it must be a common problem.
It powers up, high voltage starts up, if I don't hook it up to a computer, it shuts the high voltage and the front LED goes from green to amber flashing. which is normal but when I hook up the cable it doesn't look like it detects it? The hight volatge does not start up again or the LED does not go green. I suspect a component is faulty on the board at the neck of the picture tube as the video cable goes there only. Could it be that it has a video cable with different pinout (HD-15 type) ? |

Found the problem
Upon disassembly, I found an area where there was a lot of overheating. I found that 2 capacitors were badly overheated, C415 and C413 (101K,2KVA rating ). I changed them and the unit now had the high voltage startup but no more flashing yellow which after downlaoding the Operating manual meant that was a problem with it. Hope this helps someone else with a similar problem. "Aslaner" wrote in message ... I have this monitor, it must be a common problem.
