Hello everyone,
Got this nice monitor for a while now, I struggle to make it work again, and I read that here might be some very nice people that could point me in the right direction to repair it.
Under power the backlight won't come on, a buzzing sound starts and then fades away after a few seconds, then it starts again. Can't tell exactly from where, but I think it's the transformer in the middle of the power supply board, or around it.
The red LED in the front of the tv flashes five times, then 2-3secs off. Probably this is an error code, cant find a service manual to look it up. Are some samsungs simillar in opration, ones error code will be the same as other model's error code?
I am suspecting that the power board is faulty, but I might be worng.
If the mainboard is disconected from the power board the intermittent buzzing sound turns into a more finer continueos buzzing. The cable between the LED board and power supply board still connected at this point. Voltages at CNM803 are 12.83V(13V) and 5.32V(5V). There are two main capacitors on this power board voltages are 347V is this high enough?
any help would be apreciated,
Thanks
