Hi,

According to my brother, his T2615's power supply died. He replaced it with a 350 watt power supply and it powers up but nothing appears on the screen.
The fan is running when powered up and I checked every connector and it appears to be in place. I ALSO notice a red LED being lit when powered up; I found out that it is a memory module indicator. I am clueless right now. What could be the problem and what should I do next? Please help!

Thanks,

Kevin
Remove and reseat the RAM and all cards.. What HAPPENED when the power supply died? Perhaps other components were damaged or knocked loose during the repair.As GX1_Man suggested, I reseated the RAM module (found dust on one of the chips and around some pins, but don't know what to use to clean it), but it did not help. But I think I did not describe the problem more accurately. What I failed to NOTE was as soon as I switch the new power supply to the on position, the light on the power button turns on. Then I press the power button to turn on the PC (screen remains blank). I cannot turn off the PC by pressing the power button, I have to switch off the power supply.

I also inserted a Knoppix Linux Live CD at power up to see if it can do anything but nothing appears on the screen.

Maybe something failed or not connected correctly in regard to the power supply/power button? What specific step should I do next?

Thanks,

Kevin
Recheck all the wiring from the motherboard to the case. Something is wrong there. I found out the motherboard is L7VMM2. The case is either ATX or micro-ATX (not sure).
I was able to find the L7VMM2(2.0).pdf on ecs.com.tw.
I recheck the connection from case to motherboard and found the following possible issues:

1) The CASFAN1 is not connected but I don't think there is a case cooling fan connector (if there is one, how does it look like?).
2) There is no case LED cable (how does it look like?) connected to SJ1/LSJ1.
3) Don't know why 2 orange wires are crimped into one pin (pin 20 I think) of the ATX 20-Pin Power Connector.
4) HARD drive was connected to IDE2 so I switch it to IDE1.

And, I think the biggest suspect of my problem is:
4) PANEL1: found 3 pairs of 2-wire connectors to it. PANEL1 is for case switches and indicator for power switch, hard drive activity, reset switch, and power/sleep/message waiting LED. I suspected the connectors are not connected to exactly the right pins from what I can see. So I pull them out. To reconnect them I want to make sure exactly what are they for. 1 connector is red and WHITE wires; another is white and green wires; the third one is black and white wires. I can't find info for what they are.

Please tell me where to find the information I need or tell me what they are if you know.

Thanks,

KevinI was able to find info about the wires coming from the front panel. I spotted the wires for the power/sleep/message waiting LED was not connect correctly to PANEL1 and so I connect them to the right pins. Now the power button would not light up when I switch on the power supply (previously green light was shining up around the button). When I press the power button it powers up the PC and the amber light shines around the button. Still, nothing appears on the screen. Pressing the power button to turn off the PC still does not work. Does it matter which way the 2-wire front panel connectors go into the pins of PANEL1?

I tested the hard drive by replacing it with another working, bootable drive and it did not make a difference. (the current configuration is hard drive as master on IDE1; DVD-ROM and CD-RW as master and slave, respectively, on IDE2).

Otherwise what I observed and listed on my previous post remain the same. Please help!
