[Dead] DX 5271F Flashes green no screen then warning light beeps than it powers down

[Techboy]

I am working on a 527F When power on the green light flashes under the Z than around thirty seconds the Warning light starts beeping and maybe another 30 seconds the power switch flips to off. The Operation panel never comes on in the process.

Hi,

If you check the service manual there should be a flow chart telling you the fault. I've had this several times on iradc257 turned out to be power supply

I do not have a service manual, the green light flashes 3 times pauses than 3 more time with the yellow fault light on. The screen that never lights is 5X7 screen with no manual push buttons.

you need to check to see if any voltage is coming out of the power supply connector to the main controller but I had one recently and turned out to be main controller.
