You can desolder the B+ line to check the power back to on condition. If the power lit on.It is the int cap inside the FBT has shorted.
Happy trying.

How do I troubleshoot my motherboard on my HP Pavilion a1020n. This is my motherboard PTGD1-LA.

A) Power Supply.

One of the leading causes of computer failure.

LED lights come on? Fans spin, or spin a few times, and stop?

Bad Power Supply. Weak voltage power rail.
1) ALL of the LED lights combined use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts.

3) A typical Processor uses 51 to 125 Watts. Depends on what Processor it is. (Older Processors such as Pentium II's for example, use less)

No Processor operating = No Signal on the monitor.
No video signal.

But if you do think it's a problem with the Ol' Goldfish 3, look at the Electrolytic Capacitors on the motherboard.

Our one year old monitor comes on, but then goes black after just a few seconds. it is not the graphics card. I hooked it up to another computer and it did the same thing.

If the monitor power light on remains on, either the monitor itself or VGA cable is faulty. Move the cable to see if there is any change on the display. I'd suggest changing the cable - less expensive than a monitor. If not the cable, the monitor is faulty.

No plug in play... don't think their dead... do I need drives first?

no country stated or if not usa what is your line power?(volts AC)
your PSU is inside monitor not outside, so uses a simple line power cord. (just wires)
12 year old monitors, found, (dead)
page one of your user guide is clear, read it yet?
seems not.,
Auto-ranging, 90 to 265 VAC
1280 x 1024 @ 60 Hz, 75 Hz (never higher) resolution settings.
those are very old monitors.. worth like $10 used.
if the power lamp shows wrong, the monitor is dead.
right button is power to the right of it is a power led that must glow.
the old monitors had CCFL backlamps before year 2010.
those are back lamps, that fail fast. 20k hours, fast. (short)
first is the power switch
2nd is a working PC with at least sync signals on 2 pins
then the OSD screens work of not the monitor IS DEAD.
inside this OLD monitor is sleep time, turn if off with OSD menu's its nothing but trouble.
some have an OSD lock, so hold the menu key for 10 seconds
and it unlocks. button 2 from left is MENU.
see page 4-10
the guide is here. not too good , poor diagnosis sections


power it on, LED power , glows.
with a PC working, say running any BIOS screen only....
or running, windows, in low resolution mode 1280 x 1024
if wise set the pc up to that first. not second.
then plug in the vga cable so the MOnitor only sees that signal above. (if you do above wrong, monitor shows OUT OF RANGE on the screen)

at mon.
PUSH the OSD button, menu, if OSD is dead the montor is dead.
OSD= on screen display., (yes the LDC has brain inside)
then take a flash light . point it at screen
see data now, if yes, in the beam is data the back lamp is dead
as are most 12 years old montors now.

see those 4 cream colored connectors bottom of this PCB
those are the high voltage CCFL lamps.
2 lamps 4 ends. the lamps are bad or the board 500 to 1000vdc
power supply is dead.

My HP w2007 19" lcd monitor when turning on from sleep mode turns on for a second than turns off is this a virus

No, no virus. This is usually a power supply problem. I see this thing all the time with LCDs. If you montior is less than 3 years old Dell should replace it for you.

Just go to this link:

Type in your PC's service tag and click send them an email or do what I do and use the online chat feature. It is quick and easy. You'll need to give the very log serial number off of the back of the monitor (usually begins with the letters MX, CN, or MC).

However, if it is older than 3 years you may be stuck buying a new display. Luckily there are some great deals now on new LCDs....let me know how it goes.
