Question about HP Compaq Presario F730US Notebook

1 Answer

Compaq F730US No Display

I have a Compaq Prasario F730US and the 1-year warranty just expired.
I can power it on and the nothing show on the LCD, I hear the DVD drive spinning for few minutes then the light on the power button turn off like 1/60 second. It keeps doing this repeat and repeats again. I suspect the video chip or the MB has a problem. I reseat the memory chip, hard disk and the battery, same problem. I remove the memory chip, hard disk and the battery, and boot it up with the A/C adapter, same problem. I connect the external LCD thru the VGA, nothing show. Any suggestion will be appreciated. I don’t want to spend a lot of money to fix it since I only pay $400 for this brand last year. I can get another one about the same price with a better configuration.

    Has anyone solved this yet? Same thing happening to me.

    The same problem has happened 4 times with me. Im in Argentina and the electricity currents are not even. Eventually with persistance it powers back on.Then I clean up the hard drive, run scans, and memory test, with no negative results. I have even taken the laptop apart 2 times, cleaned the fan of debri, which actually enabled one of my recoveries. What I am begining to think is the computer gets overheated and there is a component called the heatstick. When the laptop gets overheated the computer functions in the way we have experienced, it is a protection mechanism for the processor. Keep pressing the on button, and don't let the lp get over heated. Who knows, just a guess from our mutual experience.

Dell Vostro 1400 LCD Showing Black Screen


If you connected the laptop to an external monitor via VGA and the display, then it is not "an NVIDIA GPU defect" .

The video chipset connected to the LCD screen is the same connected to the external VGA port, and is working fine since picture is OK on monitor.

More likely the problem is either LCD ribbon cable, or LCD display, the fact that the backlight is working means that the inverter is also working.

Monitor power doesn't work. does not display anything


It should be a power unit problem.
I had a same problem right after the 1 year warranty is expired and fixed it by myself.
I found 3 broken capacitors in a high temperture area on the power unit PCB and replaced them.
So far it is working good.
I think this is a defect of design of the power unit.
