No Video from DH61AG

I'm installing DH61AG into a LP-2150 AOI chassis. The power indicator turns on, I get some disk activity, but no video (no splash screen) on the AOI screen or on an external monitor connected to the HDMI port. Any ideas? Thanks.

Please provide part numbers where applicable. What processor do have you installed? What memory do you have installed? Where did you get the Apple Glen board? Used?

Part # of Mobo is BOXDH61AG AA G23736-505 BTAG24300X7N purchased new from

 

Amazon. I'm using 16 GB of RAM (DDR3 133MHZ PC3-10600 Non-ECC Unbuffered 1.5V

CL9 2Rx8 Dual Rank 204 pin SODMM). CPU is i3-2130. AppleGlen is the G23736?

Thanks,

Bob

Yes, the "AG" in "DH61AG" is the two-letter acronym for code name Apple Glen.

Nothing obvious is coming to mind from the data you've provided. You've tried with both DVI- and a HDMI-based monitors connected (I am presuming the AIO display uses the LVDS interface)? You've tried with only one SODIMM installed?

Plug a headset of speakers into the rear audio output port and see if there are POST codes being presented when you power on (note: you can also see these POST codes via flashing of front panel power LED).

I have tried it with only one SODIMM at a time as well as a DVI and HDMI monitor connection. The AIO does use the LVDS interface. Beep codes: 2 peeps, pause, 2 beeps, a little drive activity and then nothing. So what do the POST codes mean?

I think it is complaining about memory. I see that the TPS indicates that 8GB SODIMMs can be used, but this doesn't jive with my memory (no pun intended). At that point in time, I only remember 4GB SODIMMs being supported. Do you have a 4GB SODIMM that you could try?

! looked up the beep codes and they tell me there's no video processor. the i3-2130 is supposed to have HD video built in so I think there's a processor problem. In the meantime, I'll try using 4 Gig memory as well as a different processor. I'll report my results.

Well, I've tried another processor (i3-2120) and a 4 Gig SODIMM. I booted using a HDMI monitor with the LVDS monitor disconnected and all peripherals disconnected . Still get the 2 blink POST code (no video). With no memory, i get a 3 blink post. I can't see any problem except that the DH61AG mobo must be defective. I'll see if I can get a replacement.

Well that was it. A brand new out of a sealed box DH61AG mobo was defective. Replacement board works just fine with 16 GB RAM and i3-2130 CPU
