Hi Tshering,

What was the first complaint? Have you checked if the output voltages good and stable?

Hi Mubashir,

All smps (including atx) transformers are unique and it can't be used on other equipment except on the same model.

Dear Jestine, Good day

I want to ask a question regarding Switch Mode Power Supply Trasformer. is it possible that normal ATX smps Supply transformer can use in other or all smps of computers. Voltages and pin configuration is same like other smps transformer.

Thanks.

Hi Mhel,

If you connect the VGA port and it is working fine then the problem is in the DVI eeprom or even a bad MCU program. Before that make sure all the voltages from the voltage regulators ICs in the mainboard are good.

Hi Mr. Yong I have here a ibm 15" lcd monitor w/ power input of 12v using adaptor and a dvi input, my problem is when ever I'm going to connect my dvi cable to pc my screen goes black and no response but sometimes it shows some image en then blank again. With only a 12v adaptor connected it working fine and shows the no cable connected message, I tried replacing the lcd panel but still the same, even with new 12v adaptor, hope you can help me with this. Thanks in advanced
